How to feed watermelons after landing in the ground. Proper feeding of watermelons and melons

There are no limits to human dreams. I so want melons to grow the size of a watermelon, and even better, a pumpkin. Quality seed and excellent care do their job. With proper feeding, the size of melons in many melon lovers reaches incredible sizes. To do everything right, it is useful to know the secrets of growing delicious fruits.

Fertilizer classification

All fertilizers are conveniently considered according to several criteria:

1. According to the source of origin - mineral, organic.
2. According to the application method - foliar and root.
3. By aggregate form - liquid, solid, soluble.

What does a melon need to grow?

The main melon macro-and microelements are potassium, calcium, phosphorus, nitrogen, sulfur, copper, manganese, molybdenum. Without them, it is almost impossible to grow a large and juicy melon. And although they are contained in the soil, each new crop absorbs its portion of minerals.

Why do melons need nitrogen?

Nitrogen is the main structuring material for melon cells and tissues. It is an important element for chlorophyll, stimulates the growth of leaves and stems. With its deficiency, the plant withers. Chlorosis may develop - the leaves become yellow and small, brightness and juiciness are lost. 10-12 weeks - the time of flowering and pollination. Timely introduced nitrogen in the correct dosage will positively affect the formation of fruits.

Potassium for melon

Potassium works as a protective immunomodulator, strengthening melons. It helps to endure excessive heat. Participates in flowering and the formation of fruit ovaries. If its level is normal, there are much more female flowers than empty flowers. The flowers are sugary, fragrant. The bees fly on them with pleasure. Pollination is going great. More than enough fruit is tied. You even have to remove the extra ones, leaving no more than 5-6 fruits on the bush. The fruit ripens faster by a couple of weeks, compared to plants under which potash fertilizers were not applied. The sweetness of the melon fruit is proportional to the concentration of potassium in the soil. But this does not mean that you need to pour top dressing beyond measure. Any excess of potassium leads to yellowing and disease.

Importance of other minerals

Calcium provides water balance, is involved in the absorption of other substances. The role of phosphorus is especially noticeable in the growth of roots. His correct application will help melon seedlings grow strong deep roots. Iron and magnesium are active participants in photosynthesis. 4-6 weeks of melon growth is a crucial period when vegetation occurs to the maximum. It is on how it passes that the strength and strength of the plant will depend. Stem strength, number and size of leaves. All this will further affect the quality of future fruits. What the melon needs most right now is calcium and magnesium.

What top dressing, when to carry out. Timing and frequency

1. The first fertilization occurs at the time of sowing, and then planting seedlings. Starting in April, melon seeds treated with potassium permanganate are sown in a special soil mixture:

• earth -1 part;
• humus -3 parts;
• superphosphate -3 tablespoons;
• potassium chloride -1 tbsp;
• nitrogen fertilizer - 1 tbsp.

On average, seedlings need 35 days to grow.

The appearance of 3 leaves is a reason to feed. Apply complex mineral remedy.

After 7 days, the melons are fed again.

Mid-May is the time for planting seedlings in a greenhouse or open ground. Now the plants already have 5 leaves. In the wells are placed rotted compost or humus. Seedlings are planted not too deep. For melons, the well-known rule applies: the better you feed it with organic matter when planting, the higher the yield.

A week has passed and it's time to water with a nitrogen delicacy. To do this, dilute ammonium nitrate at the rate of: 20 g of the product per 10 liters of liquid. 2 liters are poured under each pet.

As they grow, 2-3 more top dressings are carried out. Everything depends on the fertility of the land. The intervals between them are 2 weeks. Solutions should preferably be alternated. What infusions can be made:

• humus;
• humus;
• litter;
• herbal infusions;

It is advisable to add wood ash to each infusion. And you can water it separately with a solution of ash once a month. Masters of natural farming advise not to mix it with herbal irrigation.

Korean Secret of Sweet Huge Melons

If sowing is done directly into the holes in early May, then all the substances necessary for the melon are poured into the soil. Best time for sowing melons in open ground, this is when a wonderful yellow carpet of dandelions has spread. They actively bloom when the soil temperature reaches 10 degrees. Koreans will never plant melons without saltpeter. For 1 well, they add 1 tablespoon of ammonium nitrate.

After the appearance of the first sprouts, a week later, the first top dressing is carried out. The same saltpeter is used. For 10 liters of liquid you need 1 Matchbox chemical agent. Dilute and mix thoroughly. Half a liter is poured under each melon.

The second feeding comes in two weeks. Use nitrophoska. The dosage this time is increased to 1.5-2 boxes. Bred all the same in 10 liters of water. ½ liter is applied under the plant.

The third dressing is one of the most important. At this point, the formation of the ovary occurs. Now it is clear that it is now that the size and quality of the fetus is determined.

Application of mineral fertilizers

It is more convenient and efficient to use complex minerals. Agritek Drip is used for melon fertigation. The terms and dosages of this drug are as follows:

• 3-4 leaves 3 kg per hectare;
• vegetation-budding period 5 kg per ha;
• during flowering and fruit set 4-5 kg ​​per ha.

The composition of the root top dressing necessarily includes superfofate-50g, saltpeter -10g, potassium chloride -20g. This is the dosage for 10 liters of water.

Top dressing with a solution of humus

The rotted humus is the most delicious delicacy of all plants. Do you know how his melons are adored. A concentrated solution is prepared from it. Before watering, it is diluted in a ratio of 1: 5. At the same time, they are applied under each plant with watering. So you improve soil fertility without synthetic nitrogen and nitrates. The infusion contains important microorganisms in high concentration. If there is a soil imbalance of bacteria, then its introduction will restore the disturbed balance.

Top dressing with herbal infusions, how to cook, what to use

Root top dressing is one of the most important measures to increase the yield of melon. Those who start doing them regularly can no longer stop. This is such an exciting process. Plants and fruits grow by leaps and bounds. And it is not just words. The infusions do contain yeast as a source of valuable bacteria for fermentation. Try to introduce top dressing and you will see how easy it is. Such top dressing is also called 3 in 1, you kill several birds with one stone at the same time. After all, here is organic matter, and watering, and sprinkling mulch.

To improve growth:

1. At the bottom of a barrel or a special container, a grass felling is laid. Nettle, goutweed, burdock, plantain, clover, wheatgrass are ideal. Let any unwanted weeds go. Grass occupies ¾, topped up with water. Add an EM preparation, half a small pack of yeast. You can put a couple of slices of bread. Everything is thoroughly mixed, covered and left for three days. The appearance of a pleasant sour fermented smell is an indicator of readiness. Diluted 1:10 and watered melons.
2. Mustard, goutweed, plantain, burdock, 5% celandine are cut into a bucket by ¾. Add 250 ml of EM, a glass of old jam. Top up with water. Mix everything well and cover. Insist until a delicious sour smell appears. Now you can use. Dilute ½ cup per 10 liters of liquid.

For productivity

For the formation of more female ovaries and the formation of fruits, an infusion is prepared in the following way. The container is ¾ filled with chopped grass - yarrow, gout, plantain, quinoa, amaranth. Fill with water. It is useful to spread the remaining silage after use under the melon plants between the rows.

Valuable organic

Organic fertilizers for melons are represented by animal and vegetable substances. When they are completely decomposed, they form minerals. The most popular organic

• humus,
• manure,
• bird droppings,
• compost.

They are rich in nitrogen, potassium and phosphorus. As well as organic fertilizers - the most valuable sources of vitamins for plants in an easily digestible form. For all gourds organic is the best fertilizer.

Humus is the best delicacy. After its application, the melon becomes prettier right before our eyes. Shoots and leaves become thick, juicy, good healthy shade.

What is the melon missing?

When the growing season is in progress, only experienced agricultural technicians can determine that something is wrong with the plants. And even do the appropriate laboratory tests. After all, when the leaves turn yellow, this happens both before a deficiency and with an excess of potassium. What about ordinary gardeners who dream of growing a long-awaited fruit? The advice of professionals is this - fertilize with a small dosage of complex fertilizer. It can be a mineral remedy of Kemira, crystals. A complete optimal set of micro and macro elements will restore the chemical imbalance of the soil. The problem will fix itself. The melon will get healthier and stronger.

How to prepare the soil before planting

In the autumn, when they carry out the autumn plowing of the future site under the melons, organic matter is introduced. The dosage is 40-60 t/ha. The deadline for the event is no later than mid-September. It is valuable. Thanks to it, microbiological processes are activated, humus is better and faster converted into useful minerals. Simultaneously with manure, a phosphorus-potassium mixture is introduced in the fall. Dose - 80-100 kg / ha. Before sowing, the melon plot is cultivated and ammonium nitrate is scattered at a dose of 40-60 kg/ha.

Agrotechnicians believe that on lands fertilized with organic matter, mineral fertilizing is not necessary. If they are not carried out, the yield will remain the same. But the quality will be higher.

Top dressing with chemical minerals is carried out without fail, if when growing plants they use drip irrigation. At the same time, the norms of pre-sowing and basic fertilizers are reduced. Sometimes top dressing is carried out in a foliar way, spraying the leaves with a special sprayer for this. Stimulants and pesticides are added here if necessary. This application has a positive corrective and structuring effect.

To get tasty and high-quality watermelon fruits, you will need to make a lot of effort. Culture at each stage of development needs a certain nutrient element, and if it is not applied on time, not only the plant will suffer, but also the future crop. Top dressing of watermelon can be carried out with mineral and organic fertilizers, and it is better to combine them, which will provide complete plant nutrition.

How to identify a nutrient deficiency

When growing watermelon, top dressing is an important procedure. You can fertilize this crop with various compositions, which are easy to purchase both in finished form and cook with your own hands. In order for the berry to grow tasty and of high quality, when it is cultivated, certain elements must be contained in the soil, the lack of which can be determined by the state of the plant:

• Nitrogen. Since this element is involved in the process of photosynthesis, its deficiency manifests itself in the form of slow plant growth, the formation of thin and short shoots, small inflorescences, and leaves with a pale green color. In addition, yellow veins appear on the lower leaves, and then on the upper ones.
• Phosphorus. Despite the fact that this element is present in large quantities in the chernozem, it is not found in the form in which plants need it, that is, they cannot absorb it. Phosphorus is necessary for gourds during the entire period of growth. With a lack of this element, the root system of plants will be weak, the leaves will be small with a characteristic gray-green or bluish tint. The main leaves located near the shoot gradually turn yellow, and brown spots appear between the veins. Then the upper leaves are affected. After drying, the leaf apparatus turns black. In addition to the fact that the growth of the plant slows down, the ovary also appears late, and new leaves form small.
• Potassium. This element controls the water balance. Its deficiency manifests itself in the form of withering of the plant. If the plant experiences a lack of potassium during the fruiting period, the quality of the berries will be reduced. To make up for the deficiency of this element in the soil, it is necessary to apply fertilizers containing potassium.
• Calcium. Thanks to this element, the vital activity of cell membranes is ensured. The lack of a substance manifests itself in the form of barren flowers and the death of ovaries. Fruits that lack calcium grow small and tasteless, and also have an underdeveloped end of the inflorescence.
• Magnesium. The lack of this element is manifested in regions with high humidity. The lack of a substance is indicated by the yellowness of the leaves and brown spots between the veins.

Mineral fertilizers for gourds

To achieve high yields gourds, macronutrients must be absorbed by plants in higher doses. Mineral fertilizers are applied to the ground during sowing. The introduction of one or another component depends on the phase of culture development. One of important elements providing nutrition to watermelon is potassium. With a sufficient amount of this substance, flowering will be stable, productivity will increase, plant resistance to pests and diseases will improve.

It is worth considering that mineral fertilizers are used after the soil is moistened, that is, after watering or rain, after which the soil is necessarily loosened. If nutrients are introduced without prior moistening, then the effectiveness of their use approaches zero. To obtain a full-fledged harvest of gourds during the entire growing season, it is required to make both minerals and organics. Fertilizers can be in liquid and solid form. Let us consider in more detail what these or those nutrients are.

Nitrogen

A fairly common mineral fertilizer is urea (urea), ammonium nitrate and ammonium sulfate.

Urea

Urea is a popular nitrogen fertilizer that has a positive effect on plant development, accelerating the process of photosynthesis. However, the excessive content of matter in the earth contributes to the rapid development of green mass. As a result, the watermelon will grow leaves and shoots, and the number of flowers will be minimal. Harvest at high doses of urea will be characterized by an unusual color and taste deterioration.
Urea is one of the most popular mineral fertilizers among nitrogen fertilizers.

Ammonium nitrate

Such a nitrogen-containing fertilizer, like ammonium nitrate, consists of 34% nitrogen. It is not recommended to feed gourds with this substance, since nitrates accumulate in the fruits, which negatively affect human health. However, if you look at it, then increased doses of nitrates can be formed only when saltpeter is applied in excess quantities. Based on this, we can say that the introduction of saltpeter under watermelon in small quantities will not bring any harm to human health.

Ammonium sulfate differs from other nitrogen fertilizers in that it contains sulfur. The advantage of this fertilizer is its lower cost compared to carbamide and nitrate. In addition to gourds, ammonium sulfate can be used for fruit bushes And vegetable crops. An important feature of this fertilizer is the fact that this substance is absolutely harmless to humans.
One of the nitrogen fertilizers, which is used as a mineral supplement, is ammonium sulfate, which, in addition to nitrogen, also contains sulfur.

Phosphate

One of necessary fertilizers for any plants, including gourds, are phosphate fertilizers or more familiar to everyone - phosphorus fertilizers (soluble phosphates). Of the most popular, ammophos and superphosphate can be distinguished.

Ammophos

Ammophos is a light gray granules that contain 12% nitrogen and 52% phosphorus. Do not confuse ammophos with ammophos, as this is somewhat various fertilizers. In addition to nitrogen (12%) and phosphorus (15%), ammophoska also contains potassium (15%) and sulfur (up to 14%).

Some gardeners are of the opinion that there is not enough nitrogen in the composition of ammophos. However, it should be borne in mind that this composition is used primarily as a phosphorus supplement. Fertilization improves the development of the root system of plants, increases resistance to diseases and weather influences, improves yield, makes the taste of fruits more tender, and also has a positive effect on the safety of the harvested crop. Ammophos is especially relevant for arid regions where soils lack phosphorus.

Superphosphate

Fertilizers such as superphosphate can be of different types:

• simple;
• double;
• granulated;
• ammoniated.

Some formulations contain magnesium, molybdenum, boron and other elements. The amount of phosphorus in the fertilizer varies from 20 to 50%. The main advantage of superphosphate is that it is a water-soluble fertilizer. This allows the plant to quickly receive nutrition when using top dressing in the form of an aqueous solution. Superphosphate is a water-soluble mineral fertilizer with a high content of phosphorus (20–50%)

Potash

Since potassium plays an important role in the development of plants, its additional application will not be superfluous at all.

Potassium chloride

One of the most common potash fertilizers for melons and gourds is potassium chloride. This substance increases the resistance of watermelon to adverse effects. environment and diseases, strengthens root system. The composition of potassium chloride includes 65% potassium and chlorine, which over time is washed out by irrigation and precipitation from the soil. Potassium sulphate or potassium nitrate can be used as a potassium supplement for plants.

Organic watermelon nutrition

Fertilizers of an organic nature can be divided into substances of animal and vegetable origin. They contain nitrogen, potassium and phosphorus. All these substances must be applied in appropriate doses.

vegetable

Humus, grass infusion, vermicompost, and wood ash are most often used as vegetable dressings.

Humus

An excellent top dressing option for melons is humus, which is a part of the soil that forms in the process of decay of plant and animal residues. The highest concentration of humus is found in chernozem soils. Rabbit droppings, horse and cow dung are used as such fertilizers.

Herbal infusion

A fairly simple and at the same time useful fertilizer is an infusion of grass. Everyone on his site during the season fights weeds, performing weeding. However, then it is not necessary to get rid of the grass by burning - it can be used to make an infusion. Although such an organic recharge will not replace humus, but complex application fertilizers will allow you to get good harvest.

Biohumus

Separately, it is worth dwelling on biohumus, because the fertilizer prepared on the basis of this component is several times superior in nutritional value to manure and rotted compost. Biohumus is an organic fertilizer resulting from the processing of organic matter in the soil by Californian worms. After the processing process, organic excrement remains in the ground, suitable for absorption by plants. The advantage of biohumus is the absence of pathogenic microflora and weed seeds. Fertilizer improves the taste of fruits and increases the resistance of plants to diseases.

Gardeners and gardeners widely use wood ash, which is a product from the combustion of wood, weeds, straw, and foliage. The ash contains components that ensure the normal development of plants. These include zinc, magnesium, sodium, sulfur, phosphorus, calcium, boron. With the timely introduction of ash into the soil, the resistance of plants to pests increases, resistance to infections and the taste of the crop improve.
One of the available fertilizers is wood ash, which contains elements such as zinc, magnesium, sodium, sulfur, phosphorus, calcium, boron.

Animals

Among organic fertilizers of animal origin, manure, bird droppings, and mullein are the most popular.

Manure

It can be said without exaggeration that manure is the most valuable and widespread organic fertilizer. Its composition may differ depending on the bedding used for animals (sawdust, straw). It is considered that the most best manure is one that uses straw bedding. Thanks to the straw, the fertilizer gets a good structure, and in the process of decomposition of organic matter, useful elements are given. Depending on the degree of decomposition of manure, the quality of the fertilizer also differs: the higher the degree of decomposition, the more high quality because it is easier for plants to absorb nutrients.

One must also take into account the fact that in fresh manure is not used, but only in rotted. Otherwise, top dressing with such fertilizer will negatively affect the immunity of plants, slow down their growth, and worsen their taste. In addition, fresh manure emits a considerable amount of heat at the beginning of its decomposition, which can simply destroy plants. Plus, this fertilizer contains weed seeds and pest eggs, which, if they enter the ground, will only bring harm.
Manure is a valuable organic fertilizer that is widely used to improve soil fertility.

bird droppings

Bird droppings are no less popular, especially chicken. The substance contains many useful elements, in particular, magnesium, nitrogen, phosphorus, potassium. The product is also characterized by rapid decomposition and active action. It should be borne in mind that in its pure form, litter should not be used, since the fertilizer has a high concentration.

Careless use of chicken manure can lead to plant burns, since uric acid is present in the composition. Litter is used, as a rule, in the form of liquid nutrient solutions, diluted with water, applied dry in the fall, and dug up in the spring. It can also be applied in the spring, but only in the form of well-ripened compost. Compost is a biological and organic matter that has decomposed under the influence of the vital activity of microorganisms.

Mullein

Mullein is a fertilizer loved by many gardeners, used as top dressing and is an infusion cow dung. The product is environmentally friendly. It contains a large amount of nitrogen, calcium, potassium and phosphorus, as well as a number of other useful elements. Mullein is a fermented mass, on the surface of which there are always small bubbles.
Mullein infusion is widely used for fertilizing various garden and horticultural crops

Which is better: mineral fertilizers or organic

The opinions of gardeners regarding the use of fertilizers differ: some prefer only organic matter, others believe that without mineral fertilizers a good harvest cannot be obtained. How is the situation really? At this point, it is worth understanding in more detail in order to understand which fertilizers are more preferable and why.

To begin with, it should be noted that organic fertilizers are characterized by a longer action compared to mineral fertilizers. This is due to the slow decomposition of organic matter in the soil, which helps to improve its structure, as well as the accumulation of humus. However, it should be noted that frequent use organic dressings will contribute to the accumulation of nitrates in plants. This is due to the content of nitrogen in such fertilizers.

The advantages of mineral fertilizers include ease of use. Today it is possible to purchase the necessary formulations for specific plants, but even such fertilizers are unable to solve the issue of soil fertility. In addition, some substances acidify the soil, so the use of minerals on acidic soils without liming will be useless. This is due to the fact that most vegetable and fruit crops prefer neutral, slightly acidic and slightly alkaline soils. Concerning acidic soils, then plants cannot absorb nutrients on them. So, for growing watermelon, neutral soil is needed, i.e. pH = 7.

Organic fertilizers can be successfully applied without chemical elements. In the case of using mineral fertilizers, sooner or later you will have to add compost to improve the soil structure. However, using only organic matter, it is unlikely that it will be possible to achieve high yields, which is due to the lack and wrong balance. nutrients. Although organic fertilizers contain nitrogen, it is not enough in the required time frame. Therefore, top dressing with minerals in the correct proportions has a positive effect on the growth, development and fruiting of crops. This suggests that organics and minerals complement each other and both types of fertilizers must be used.

Feeding watermelon with folk remedies

Among the variety of fertilizers, folk remedies are no less popular for fertilizing. These include yeast and ammonia.

Yeast

For yeast dressings, ordinary baker's yeast is used. A nutrient solution based on such a component performs the following functions:

• increases soil fertility;
• stimulates plant growth.

Improving fertility occurs due to the content of beneficial microorganisms in the yeast, and the root system develops several times faster with such top dressing. As a result, a stronger plant develops, which at the same time receives more nutrients.
For watermelons, you can prepare a nutrient solution from ordinary yeast, which contains beneficial microorganisms.

Ammonia or ammonia (ammonia) can sometimes help in the process of growing watermelons. Since the substance contains nitrogenous compounds, plants receive the necessary substances during processing for both shoots and leaves. However, the use of ammonia should be resorted to only as a last resort, that is, when the plant cannot be saved in other ways.
Ammonia (ammonia) is often used to fertilize garden crops, since the substance contains nitrogenous compounds.

Any plants in the garden can be fed root and foliar method. Root top dressing- the main method of introducing nutrients into the soil near the root system of the plant, which ensures its normal growth and development. The root method can make both minerals and organics in liquid or solid form.

Liquid organics can be prepared from slurry, mullein, bird droppings or wood ash. Such substances are introduced during the period active growth plants, i.e. in May - early June. In addition, liquid organics are used for slow growth and a noticeable weakening of plants. Solid organic fertilizers, such as manure from farm animals, poultry and rabbit droppings, are incorporated into the topsoil in the autumn.

If preference is given to mineral fertilizers, then highly soluble substances should be used for root dressings. These include nitrophoska, carbamide, ammophos and others. Insoluble mineral fertilizers (nitrogen, potash, phosphorus) are applied to the soil in autumn. By spring, the earth will be fully saturated with these beneficial substances and the plants will be able to absorb them normally.
Root top dressing is the main way to introduce nutrients into the soil near the root system of the plant.

Watermelon foliar feeding, also called foliar feeding, is the application of nutrients through the leaves rather than through the root system. The peculiarity and advantage of this method of fertilizing is that the nutrients get into the plants faster, compared to the root method. However, with the foliar method, it is impossible to provide plants with a large amount of nutrition. Foliar top dressing is used most often for the introduction of micronutrient fertilizers in small quantities, i.e., it is as an additional to the root top dressing.

To distribute the nutrient solution over the stems and foliage of plants, they resort to spraying. It is best to do this procedure in the morning or evening hours. In the daytime, you can spray only in cloudy weather, which will allow the composition to linger on the leaves for more long time. Regardless of the fertilizers used, organic or mineral, you need to be careful about the concentration of the solution. Too concentrated formulations, especially with nitrogen fertilizers, can burn the leaves. In spring spraying, i.e. when the foliage is young, less weak solutions should be used than when treating coarse foliage. Urea has received the greatest distribution during spraying: it can also be used in higher concentrations compared to other nitrogenous substances.
Foliar top dressing is applied by spraying the stem and leaves of plants, which allows short time deliver useful elements to the plant

Fertilization scheme for watermelon

As the watermelon develops, feed the plant several times. Depending on the phase of development of the crop, certain fertilizers are applied. When sowing seeds, it is necessary to use fertilized soil mix, consisting of earth and humus in a ratio of 1: 3, as well as potash, phosphorus and nitrogen fertilizers, 1 tbsp. l.

Fertilizers for watermelon seedlings

When growing watermelon seedlings, it must be provided with nutrition so that the plants do not lack any element. During the growth of seedlings, it is necessary to feed 1-2 times. One of the most suitable fertilizers for this purpose is bird droppings. To prepare a nutrient solution, the litter is mixed with water in a ratio of 1:10, after which the plants are watered. In addition to litter, you can also use mullein, the fertilizer from which is prepared in a similar way. If preference is given to mineral fertilizers, then it is best to use urea. Dilute the substance in accordance with the instructions. The listed fertilizers contain a large amount of nitrogen, which is necessary for plants on initial stage growth.

As for the top dressing itself, the first time the seedlings are fertilized when two true leaves are formed, the second time - 2 weeks before planting in open ground or a greenhouse. Wood ash has a good effect on the development of seedlings. It can be applied in different ways: pour a small amount under the root or dilute 1 tbsp. ash in 10 liters of water and water the plants with a nutrient solution.
The first time watermelon seedlings are fed when two true leaves are formed, the second time - 2 weeks before planting on permanent place

Top dressing after planting in the ground

2 weeks after planting seedlings in a permanent place, they are fed with ammonium nitrate. To prepare a solution in 10 liters of water, dilute 20 g of the drug and spend 2 liters per plant. Instead of mineral fertilizers, organic fertilizers can also be used: dilute mullein (1:10) or bird droppings (1:20) with water, add 30 g of superphosphate and 15 g of calcium chloride to a bucket of composition.

You can also provide plants with the necessary nutrition with an infusion based on green grass. The essence of preparing fertilizer is to fill a large container with green grass, followed by the addition of water and infusion for two weeks or more: the mixture must ferment. Wood ash or chicken manure can be added to the composition, thereby increasing the nutritional value of the solution. After fermentation, the resulting solution is diluted 1:10 with water and watered 1 liter under a bush.

Resorting to folk remedies, after transplanting, watermelons can be fed with yeast. The use of this type of fertilizer allows the plants to transfer the pick almost painlessly. Raw yeast is best suited for preparing dressings, but gardeners often use dry yeast. To prepare a nutrient solution from yeast, you must perform the following steps:

1. Dissolve 100 g of the substance in 3 liters of water with the addition of a small amount of sugar (1 tsp).
2. The solution is infused for 7 days, after which it is diluted with water in a ratio of 1:10.
3. Under each bush pour 1 liter of fertilizer.

Feeding before flowering

In the budding phase, watermelons also need to be fed. As food, you can use 4 g of calcium chloride and ammonium nitrate, as well as 6 g of superphosphate per plant. Fertilizers can be applied dry by watering before and after the feeding procedure.

Top dressing at fruit set

During the ovary period, it is best to use complex fertilizers for melons to feed watermelons. If there are none, then the plants are fed 2 times with a frequency of 15 days. Used as a nutrient boric acid which gives sweetness to fruits. To prepare a solution, 5 g of acid is diluted in 5 liters of water and foliar top dressing is carried out. To perform potassium-magnesium top dressing, it is necessary to dissolve 2 Asparkam tablets in 0.5 liters of water. The solution is also applied foliarly.

When setting fruits, top dressing can be done with the following fertilizer: superphosphate (10 g), potassium salt (35 g), ammonium sulfate (24 g), which are dissolved in 10 liters of water and watered plants under the root, 2 liters per bush. Although superphosphate dissolves in water, it must first be poured with boiling water. Potassium in such a feed accelerates ripening, and phosphorus is responsible for the size of the fruit. However, it must be taken into account that an excess of phosphorus will lead to the formation of small fruits.
Proper and competent feeding of watermelons contributes to friendly flowering and good fruit set.

To provide watermelon with the necessary microelements throughout the growing season, the plant is fed at intervals of 10-15 days with foliar fertilizers. You can, for example, use Uniflor-micro (2 tsp per 10 liters of water) or other drugs: Master, Terraflex, Kristallon, Novofert, Nutriflex. Substances are used in accordance with the instructions, which indicate the required dose and application phases. If the plant has stopped growing, has small or yellowed leaves, a fragile stem, there is no flowering, then it's time to apply ammonia tincture. To prepare a nutrient solution, dilute 3 tbsp. l. substances per 10 liters of water. Then mix well and water the watermelon bushes, avoiding contact with the leaves.

It must be understood that there is no universal scheme for feeding gourds and any other crops. Much depends on the composition of the soil, the region of cultivation, the condition of the plants, which must be constantly monitored and the necessary substances must be applied in a timely manner. The main thing is not to overdo it. If organic matter was mainly introduced into the soil, it is necessary to introduce less nitrogen and more phosphorus fertilizers. If the earth, on the contrary, lacks humus, more nitrogen is required.

Despite the seeming difficulty, get sweet and large fruits watermelon can each on his own personal plot. To do this, you will need to follow the rules of agricultural technology and, paying attention to the condition of the plants, carry out the necessary feeding in a timely manner. After all proper nutrition in desired period plant development is the key to a quality crop.

Watermelon is a summer, sweet berry that is enjoyed by both children and adults. Today, it is cultivated not only in open ground, but also in greenhouse conditions ....

Watermelon is a delicious and desirable delicacy for most adults and children. He attracts not only his appearance, but also juicy, sweet pulp that literally melts in your mouth. Apart from their palatability, this sweet berry also has beneficial properties. Minerals, fiber, carbohydrates and vitamins - all this is in watermelon. But to get this useful product on your site, you need to take good care of the plantings, protect them from diseases and pests, water and feed the crop in time.

Do I need to feed watermelons

It is impossible to answer this question unambiguously. Of course, the choice of variety plays a big role, but most often the result depends on proper care. In addition, the size of the crop is strongly influenced by the geographical location and composition of the soil:

• In the south, in the fertile chernozem zone with a climate most suitable for growing heat-loving crops, top dressing is almost not required.
• In the central part of Russia, as well as in the east, where a sharply continental climate prevails, growing watermelons without top dressing is an almost hopeless business. In the absence of care, at best, the fruits will grow the size of a large tomato.

Watermelon is a heat-loving crop that requires careful care and fertilizer.

However, as in any business, when using dressings, you need to observe the golden mean. With excessive fertilization, watermelons develop poorly, fruit growth slows down, and taste quality deteriorates. Most gardeners agree: you need to feed watermelons, but in moderation.

A lack of nitrogen affects the general condition of plants (pale color of leaves, thin and weak shoots, small inflorescences, slow growth). If this element is part of the top dressing, then there is a rapid growth of leaves, but it is not enough to set fruits.

Thanks to potassium, nutrition exchange, photosynthesis, and cell division are more intensive in plants. One of the most important properties potassium is an increase in plant resistance to pathogenic microorganisms and adverse conditions.

The main stages of fertilizing watermelon melons

There are many options for distributing fertilizer throughout the season. But when growing watermelons, it is best to apply a feeding scheme according to the stages of plant development. There are five main stages of fertilization:

• before planting seeds in the soil;
• when planting seedlings in the ground;
• during flowering;
• after fruit set;
• during maturation.

It is important to remember that before each top dressing, the plant must first be watered with warm water, and only then fertilized.

Top dressing when sowing seeds

Before planting watermelons, you need to find out the composition and acidity of the soil on the site. After that, you need to do the following:

• Deoxidize heavy soil with wood ash.
• Fertilize excessively light sandy and sandy soils with humus at the rate of 30 tons per hectare.
• For alkaline and calcareous soils, it is necessary to provide a sufficient amount of minerals, almost twice as much as usual. You can divide top dressing into two parts (during planting and after).
• Fertilize the earth with ammonium sulfate, peat, bone meal.
• Create good drainage to let the soil breathe.

When sowing seeds in open ground, fertilizing is most often carried out with mineral fertilizers containing phosphorus and nitrogen, such as:

• Terraflex,
• Master,
• Gringo.

Terraflex fertilizer provides the most favorable conditions for the growth and development of plants drip system glaze
Fertilizer Master, containing microelements in the form of chelates, promotes better survival of seedlings and increases the resistance of plants to diseases

In each hole for one part of the soil, it is necessary to make:

• 3 parts of humus;
• 3 art. l. fertilizers containing phosphorus (ammophos or superphosphate);
• 1 st. l. potash fertilizer (without chlorine!),
• 1 st. l. nitrogen-containing preparation (ammonium nitrate or ammonium sulfate).

It must be remembered that watermelons need potash and phosphate fertilizers more than nitrogen.

With insufficient nitrogen content in the soil, watermelon leaves have a pale color.

After planting the seeds in the ground, you need to carefully shed the soil again with a ready-made nutrient solution for melons (you can use Kristallon, Novofert, Nutriflex, Green-Go, Terraflex).

You can not water watermelons and dilute fertilizers for top dressing with cold water.

Fertilizing when planting seedlings

Seedlings of watermelons grown in cassettes or other containers, when 4-5 true leaves are formed, should be planted in open ground.

Watermelon seedlings are transplanted into pre-prepared nutrient soil

Before planting, treat the soil with Fitosporin solution to kill all pathogens and viruses. Many experienced gardeners it is advised to add green manure crops (rapeseed, oats, mustard, etc.) mowed and mixed with soil into the prepared ridge. This is a powerful and environmentally friendly top dressing, which gives strength for the development of the root system and the growth of a healthy above-ground part. Green fertilizers can serve as a great replacement:

• antiseptic (since they suppress pathogenic microorganisms);
• humus (have almost the same effect as after making rotted manure);
• soil deoxidizer.

Under watermelons, it is good to make beveled green manure

A good substitute for biohumus is Ecochudo (without chemicals), which is needed just at the transplant stage. The composition is added to the soil and mixed thoroughly. For fertilizer, you can also use similar preparations from other manufacturers.

Ecochudo is a product of manure processing by earthworms, which is easily and quickly absorbed by plants.

Fertilizer during flowering

During the flowering of watermelons, it is worth paying Special attention for potash fertilizers. It is because of the deficiency of this substance that you may not see flowers at all. During this period, drugs such as:

• Nutrivant Plus (2 kg per 200 liters of water);
• Kelik Potassium (1/2 liter per 100 liters of water).

It is also important to feed melons with fertilizers containing magnesium. The lack of this element leads to the appearance of unhealthy spots on the leaves, multi-colored edging, and subsequently to the death of tissues. With magnesium deficiency, fruit setting does not work, as they simply do not ripen. For top dressing, you can use magnesium nitrate (2 kg per 200 liters of water).

Proper and competent feeding of watermelons contributes to friendly flowering and good fruit set.

great danger to flowering plants presents a windy hot weather. It is under such conditions that acute shortage calcium, which can lead to the death of the ovaries or infertility. Foliar top dressing with drugs will help to avoid this:

• Calcinitis (800 gr per 100 liters of water);
• Nutrivant Drip.

There is also a special top dressing for watermelons during flowering - Speedfol Amino Flowering and Fruiting. It should be used at the rate of 200 ml per 200 liters of water.

The Spidfol Amino line of drugs is used to eliminate nutritional deficiencies and quickly overcome stress. Kelik Potassium is a Spanish-made liquid chelate fertilizer that contains 50% potassium Calcinite or calcium nitrate is a water-soluble fertilizer that promotes growth and fruit set even under unfavorable conditions. weather conditions

Top dressing at the beginning of fruiting

one more milestone is the moment of emergence of ovaries. Sometimes melon can please the gardener abundant flowering, but there will be very little fruit. Most often this is due to a deficiency of boron, which is responsible for the proper development of cells. Its insufficient amount leads to the death of fruits or empty flowers. In the garden, boron deficiency is easy to determine by the yellow longitudinal stripes on the fruits.

Boron must be constantly used for root and foliar dressings. To protect watermelons from problems, you need to fertilize the beds with preparations at intervals of 15–20 days:

• Boroplus;
• Blank sheet;
• Mag-boron;
• Plantafol;
• Megafol (2 liters per 300 liters of water).

Fertilizer for fruit growth

After the formation of the ovaries, a very important period begins, for which so many efforts have been made. To get a good harvest, you need to make all the necessary top dressing in a timely manner:

During the period of growth of watermelon fruits, you need to monitor the timely application of fertilizers.

One more thing to consider the most important nuance: when reaching a berry right size it is necessary to stop fertilizing and watering watermelons.

Alternative feeding option

For those who are not ready to perform a rather complex set of watermelon dressings throughout the season, there is an alternative. It is enough to place 6 granules of AVA fertilizer in each hole before planting. This mineral supplement dissolves gradually and supplies the plant with all the necessary substances.

The drug AVA appeared on the market for a long time and has proven itself among gardeners and gardeners.

Mineral fertilizers for watermelons

Among gardeners and gardeners, mineral fertilizers are invariably popular, such as:

• ammonium nitrate;
• urea.

This group also includes ammonia, which is an aqueous solution of ammonia. Homeowners often use this pharmacy remedy as a replacement nitrogen fertilizers. Is it possible to use chemicals with a high nitrogen content to feed watermelon beds? Let's find out.

Urea (urea)

This is the most common nitrogenous fertilizer, which helps the crop grow better, stimulates the growth of leaves and shoots, and accelerates the process of photosynthesis. But at the same time, an excess of urea in the soil leads to an excessive growth of green mass. Everything vitality plants go to the growth of leaves and shoots, flowers are formed in a small amount. Ripe fruits will have low taste and uncharacteristic color.

Depending on the dose of application, urea (urea) can improve plant growth or slow down its development.

The correct scheme for the use of carbamide is 3-4 top dressings with an interval of 4 weeks. Fertilizer is applied about a month after planting seedlings in the ground. You need to add 10-12 grams per 1 m 2.

As a rule, urea is used in advance, in early spring or before autumn plowing. But it is allowed to use the substance during irrigation or during the next loosening of the soil.

Saltpeter

Ammonium nitrate or ammonium nitrate is 34% nitrogen. Only those crops that easily remove chemical compounds from tissues can be fertilized with this substance. Melons tend to accumulate nitrates inside the fruit, which adversely affects human health. Watermelons should not be fed with saltpeter.

Ammonia, or an aqueous solution of ammonium hydroxide, has a strong pungent odor. Everyone knows that thanks to this smell, many people were brought to their senses after losing consciousness. Does ammonia help revive watermelons? Yes, in some cases, such top dressing saves plants. Thanks to nitrogen compounds, they receive the necessary substances to feed the leaves and shoots. However, this method should only be used if the plant is already really withered and there is no chance to rehabilitate it in another way.

Ammonia (ammonia) is often used to fertilize garden crops

In order to properly prepare the solution, you need to dilute 3 tbsp. l. ammonia in 10 liters of water. Thoroughly mix the mixture and carefully water the watermelon bushes so as not to touch the above-ground parts.

organic top dressing

Like any melon culture, watermelons are responsive to organics. Combinations and types of such fertilizers are very extensive: from baker's yeast to the notorious chicken manure. Consider the most popular of them.

Such dressings perform several functions at the same time:

• Increase soil fertility, as they are a source of beneficial microorganisms (single-celled bacteria);
• Stimulate plant growth. As a result of numerous experiments, it was found that the roots develop from 2 to 10 times faster when fertilized with yeast. This means that the plant itself becomes more powerful and receives more nutrients.

It is best to feed watermelons with yeast during the transplant period. Thanks to the substances that are released from the product, picking is painless for the plant. It is raw baker's yeast that is suitable for fertilizing gourds, but many gardeners do not neglect dry ones either.

For the preparation of fertilizers, it is better to use raw yeast.

Yeast fertilizer is prepared as follows:

1. To begin with, dissolve 100 grams of the product in 3 liters of water, adding a little sugar for a better reaction.
2. Infuse this solution for about a week, then dilute again, taking 1 cup per 10 liters of water.
3. Water the plants, spending 1 liter of top dressing under each bush.

Approximately the same sourdough is obtained if bread crusts are infused in water. The fermented infusion is diluted in a ratio of 1: 3 and watermelons are watered every 7 days.

And one more interesting way preparation of yeast tincture:

1. To 100 g of yeast add 2 tbsp. l. sugar, 2 grams of ascorbic acid and a handful of earth.
2. All this must be insisted in 5 liters of water.
3. Water at the rate of 1 liter of solution per 10 liters of water.

Beloved by gardeners and indispensable for plants, mullein (infusion of cow dung). This is an environmentally friendly product, rich in organic compounds and incredibly useful.

Cow dung, like the rest of animal droppings, is used in a rotted form. Most often, it is soaked and insisted along with straw. This gives additional benefits, since rotted straw also has beneficial features for soil. Prepare the solution as follows:

1. Soak manure in water. The recommended ratio is 1 bucket of dry fertilizer per 100 liter barrel of water.
2. Mullein is infused from several days to 1.5–2 weeks, depending on the ambient temperature.
3. Watering is recommended at intervals of 7-14 days. For one watermelon bush, 1-2 liters of diluted mullein is enough.

Mullein infusion is one of the valuable organic fertilizers

There is a nuance that few gardeners know about. Manure worsens the taste of the berry, slightly slows down the growth and vegetation of plants. Mullein should be used within reasonable limits.

Mullein has already appeared in stores in 2-5-liter cans. Barrels of ready-made infusion for fertilizer on an industrial scale are also on sale.

Video: how to cook mullein correctly

This fertilizer is rich in chemical elements - potassium, magnesium, nitrogen and phosphorus - all that the plant needs in the first place. But it should be borne in mind that chicken manure is more concentrated and should be used more carefully than mullein. Uric acid, which is contained in the litter, is very dangerous for the plant, as it can easily cause burns. You can not use this organic raw material fresh, it is necessary to dilute the dry product with water.

Chicken manure is considered the best in comparison with other organic fertilizers.

Chicken manure for top dressing is used as follows:

1. In order not to harm watermelons with excessive concentration, you need to dilute raw materials with clean water in a ratio of 1 to 20.
2. You need to insist for 10 days in the open air.
3. Watering directly under the root is not recommended, it is better to do it near the hole or in the aisle.

Some experienced growers advise soaking chicken manure to rid the infusion of excess acidity. To do this, raw materials are soaked in a bucket with water, kept for several days in the open air, the water is drained, and then a new one is added. And so they repeat several times.

The concentration of nutrients in chicken manure is almost 3 times higher than in other organic fertilizers. Thanks to this, it has an effect even after 3-4 years after being introduced into the soil.

wood ash

Furnace ash is the most popular among the people. It is a natural material that does not contain chlorine, salts, harmful impurities, and is easily digestible. Ash should be applied directly to the soil in a dry form, preferably before sowing. Watermelon culture responds well to such top dressing, especially during the picking period, when the plant needs a complex of nutrients for better root survival and healing.

Wood ash can be used as potash fertilizer

Juicy watermelons can be grown not only in warm and fertile regions, you just need to choose the right variety. Only at first glance, the process of growing these sweet fruits may seem very complicated. It is required to strictly observe the fertilizer application schedule, and then the result will not be long in coming. Moreover, part of the top dressing is almost always at hand, and most of the preparations can be successfully replaced with organic fertilizers obtained on your own personal plot.

It also takes a lot of effort and time to grow watermelons to get really excellent harvest. The main rules for growing watermelons are the constant monitoring of the soil moisture index, the elimination of pests and the correct application of fertilizers to the soil.

To get a good crop yield, every gardener needs to know how to feed watermelons.

Watermelons are annual plants that prefer light, moisture and warmth. However, not all gardeners know what to do when the climate of the region is not suitable for growing gourds. This issue has long been resolved in the agricultural sector with the help of cultivation in greenhouses.

This requires the following conditions:

• optimal lighting system;
• air humidity 60–70%;
• note that the temperature during the day should be from 25 to 30 degrees, and at night up to 17 degrees.
• sowing and planting seedlings are carried out in fertile drainage soil;
• the depth of the root layer is not less than 30 cm.

The disadvantage of this or that useful element in the soil can be seen from the external state of the plant:

1. Phosphorus. Exhausted roots, inanimate-looking leaves of a dirty greenish color, small fruit ovaries, main leaves (located at the base of the process) of a bright yellowish color with brown spots.
2. Potassium. Fast drying, leaves are yellow and burns from the rays of the sun are visible, incorrectly developed.
3. Calcium. Coagulation of young leaves, flowers are barren, ovary is poorly created, small fruits without taste, which are often referred to as "herbaceous".
4. Magnesium. Yellowness of adult leaves, development of brown spots after a burn.
5. Manganese. A dull greenish hue is the plane of the foliage, you can often see their yellowness.
6. Iron. It is expressed in young foliage in a variant of dull greenish chlorosis.

Would you like to get a wonderful harvest of gourds? You should carefully monitor the state of cultures. Timely detected signs of micronutrient deficiencies and fertilization are the key to an excellent harvest.

Do not forget that watermelons must be thoroughly watered in advance, and only after the water is completely absorbed into the soil, you can fertilize the plants. Otherwise, there is a great opportunity to burn the roots of plants.

Growing watermelons in open ground

To get excellent watermelon sprouts, seeds should be sorted. One simple method is to soak the seeds in a 5% mixture of water and edible salt.

For sowing, it is necessary to use seeds that are in the liquid at the bottom, the so-called heavy seeds. It has been established that watermelon seeds differ in density. To soften the shell a little, the seeds need to be lowered into a container with water at a temperature of + 30-35 degrees.

Planting a watermelon must be carried out at a soil temperature of up to thirteen degrees, a depth of up to twelve centimeters is also provided. Moreover, the depth for seeds depends on the type of watermelon and the composition of the earth, as a rule, they are laid to a depth of four to seven centimeters.

The area for growing watermelons in the open field should be well lit. Preferably, sands or a composition of sand and 3-10% clay are suitable for planting watermelon. In spring, the following fertilizers should be applied to the soil (proportion per hundred square meters):

• compost or humus (up to a kilogram);
• 4 kg of mineral phosphate fertilizer;
• 2.5 kg of potassium chloride - top dressing is carried out before digging the earth.

When growing watermelon and melon in open ground, seeds are planted in mid-May, when the crop was grown in seedlings, then at the end of May. In the second case, the holes must be irrigated with 2 liters of water; when planting, the plants are buried to the cotyledon.

When planting in rows of culture, 1-1.4 m are placed, a distance of 0.5 m is maintained between rows, placing plants in a checkerboard pattern. 3-4 seeds should be placed in the holes - after germination, 1-2 strong crops are retained.

After planting the seedlings, the plants must be shaded, in order for the seedlings to take root better in the new area, during the first 14 days the plants are watered warm water(watering can be combined with top dressing).

The first time the plants need to be fed approximately a week after planting the seedlings or in the phase of 3-4 leaves. To do this, thirty grams of ammonium sulfate is dissolved in a bucket of water, mineral phosphate fertilizer forty grams and fifteen grams of potassium salt.

How can you feed watermelons after they are planted?

Feed the plant organic elements, using mullein in a ratio of 1:10 in relation to water or an infusion of bird droppings, 0.5 kg of this element per 10 liters of water.

During the formation of ovaries, the III final fertilization is performed. To do this, dissolve in a bucket of water: ammonium sulfate - 20 grams, superphosphate - 10 grams, potassium salt - 35 grams. Given two liters per plant.

In addition to the revised manipulations for the care of watermelons in open soil, it is necessary to carry out constant loosening of row spacing with the elimination of weeds and watering.

organic fertilizers

There are 2 types of fertilizers:

• vegetable fertilizer;
• animal fertilizer.

Two types are fully able to compensate for the number mineral nutrition required by plants. These are nitrogen, potassium salts, phosphorus, vitamin elements that are better absorbed by plants. Humus is an ideal fertilizer. It is formed as a result of the decomposition of fragments of plants and animals.

Cow and bird droppings are often used as fertilizer. However, it is necessary to use it only after the final overheating, otherwise, instead of being useful, it can be harmful: weaken the immunity of plants, stop growth, worsen the taste.

It is necessary to stir the humus for watering plants in water 1: 5, and after that you need to water the soil with fertilizers. This is necessary so that ripe watermelons do not absorb nitric acid salts.

It is necessary to replace the fertilizer with diluted humus and manure with watering grassy infusion, including bacteria that fight harmful microflora, and also lower the level of soil acidity. All kinds of herbs are suitable for this. And when a little wood ash is added to the solution, then in the future you will get very sweet fruits.

mineral fertilizer

They contain mineral salts that plants prefer. Such fertilizers are of two types - simple and multilateral. In accordance with this, simple ones consist of one component, and complex / multilateral ones, from several.

With any root dressing, simple mineral elements are introduced: fertilizer in the amount of 40-50 grams; ammonium nitrate, 10-15 grams; potassium chloride, about 30 grams. They are bred in a ten-liter bucket of water and the plants are watered every time with root fertilizer.

In the "diet" of plants should be the following mineral components: calcium, magnesium, sulfur, phosphorus and nitrogen. It is necessary to introduce top dressing at a time when the earth is rather wet, that is, after a rain has passed or after watering.

After the introduction of top dressing, the soil should be loosened. As for the elements required for the excellent nutrition of watermelons and melons, potassium comes first. The activity of flowering of female flowers, the stability of plants to various diseases, ripening stability and yield intensity.

Taste qualities also directly depend on the amount of calcium: with sufficient calcium in the soil, the fruits are sweeter, include more ascorbic acid, and the ripening process takes place faster.

Most optimal time introduce fertilizers for watermelons, and also melons in the calcium and magnesium version - from 4 to 6 weeks, at the time of intensive vegetative growth. In the period of fetal development, from 10 to 12 weeks after planting seedlings, nitrogen fertilization will be effective.

Mistakes when combining types of fertilizer when growing watermelons

Do not take into account the composition of the earth when calculating the required nutrient compositions for melons. For watermelons, poor land threatens with a sudden decrease in yield, crushing of fruits, deterioration in taste. In a good chernozem, an excess of nitrogen leads to an increase in leaf mass, and the fruits will receive less mineral elements.

Nutritional deficiency during seedling cultivation. Gardeners try to feed watermelons after planting, neglecting to fertilize the soil in the fall.

Do not alternate fertilizing with mineral and organic elements. If we are talking about organic substances, then it is necessary to alternate one type with another during vegetative growth.

They make top dressing in dry land and do not loosen after. You should wait for natural rain or water the soil before feeding watermelons.

The content of mineral elements of the soil is not taken into account. With a huge ratio of organics, more phosphorus and less nitrogen are needed. When there is not enough humus, nitrogen fertilizers will be needed.

Carry out top dressing at the time of prolonged cloudy weather. With a lack of lighting, watermelons do not absorb food well, and this leads to an overdose.

Advice! Apply fertilizer in accordance with the content of mineral components in the soil, so as not to overdose on nutrients.
