Top dressing of grapes: types of fertilizers and dosage. Correct feeding of grapes in different seasons

In August, the vineyard already pleases with the first fruits. Early and middle varieties ripen. Themselves are drawn into the mouth of the berries of new and experimental varieties. They also need protection: not so much from insidious fungal diseases as from gluttonous wasps. All this is combined with the care of the vine. On grapes in August, green operations continue, wilted, albeit ripening, bushes may require additional moisture.

Chasing grapes in August

In mid-August, I carry out activities for vine... Such an operation promotes better maturation of the vine and prepares the bush for winter.

• When chasing, the tip of the shoot is pinched 15-20 cm.
• The tops are usually removed by hand, and if you use a tool, then do not forget to disinfect it after each bush.

1. Minting is carried out when the shoots have grown and it is clearly visible what needs to be removed.
2. Beginners should be careful, because in response, the plant may begin to form stepchildren more actively.
3. In addition, you need to watch so as not to break off too many leaves, which will negatively affect photosynthesis.
4. To control the result, novice winegrowers can be guided by the following figures: after minting, there should be approx. 15 leaf blades and 10-15 buds.

Chasing is an important agronomical technique when it is necessary to carry it out, especially in regions with a short cold summer and a lack of light and heat.

The advantages of minting are obvious:

• Nutrients are not consumed for shoot growth, but are redirected to the bunches and hibernating buds.
• In addition, berries on late varieties ripen faster.
• Lignification of green bark is accelerated.
• All this increases the winter hardiness of the grapes and contributes to high yields for the next season.

Watering grapes in August

1. Watering the grapes in August should be moderate.
2. The bush does not need a lot of water as it does in spring and especially summer.
3. But if the summer is very hot, then you can periodically water in small quantities.

Top dressing of grapes in August

• Watering is combined with fertilization with phosphorus-potassium compounds: we dilute 5-10 g per bucket of water.
• Potash fertilizer can be replaced with wood ash. In this case, the dosage will need to be increased by 2-3 times. Wood ash contains a lighter form of potassium, which is absorbed more quickly by grapes. It also contains trace elements and a little phosphorus. Phosphorus strengthens the skin and protects the berries from cracking.
• If the vine does not ripen well, then you can treat the vine and leaves with potassium monophosphate 1 time in 10 days.

Also, for foliar feeding of grapes of late ripening periods, you can use the solution:

1. In a bucket of water, 200 g of superphosphate, 50 g of potassium salt, 5 g of sulfate salts of manganese, copper, zinc are diluted. Spraying is carried out on the leaf before the ripening of the bunches in cloudy weather or in the evening.

Diseases and pests of grapes in August

For the prevention of dangerous mushrooms - mildew and - effectively used on grapes wood ash... According to my observations, it perfectly protects the bushes from many diseases.

1. For prophylaxis, after watering, I recommend sprinkling the surface of the ground near the bush with ash - an effective measure, proven by many years of experience.
2. If you constantly apply ash under the bush from spring to autumn, then you can either completely do without spraying with copper and sulfur-containing preparations from mildew and oidium, or carry out them for prevention a couple of times per season.

Diseases are most dangerous during harvest, because apply treatments chemical means on fruiting bushes it is impossible. In this case, spraying like Baktofit , Fitosporin , Fitop-Flora-S and etc.

Also, in August, we protect the bunches of grapes as they ripen from wasps and birds.

• To hide the berries, you can use special bags or any non-woven material.
• Another option is treatment with a special preparation-trap for wasps. It is diluted in water according to instructions and acts as a bait.
• As a bait, improvised means will also work. Honey, beer, jam diluted with water also help fight annoying insects.

Additionally about seasonal work in the vineyard, read the articles.

Grapes are considered unpretentious plant however, for correct growth and good harvest it is necessary to feed grape seedlings in the first stages of its growth, so that in the future the berries are juicy and tasty.

Fertilizers

In order for the feeding of the grapes to be correct, you need to know which elements the plant needs most. Which fertilizers should be applied at the root and which should be used for spraying the leaves.

Nitrogen fertilizers for grapes

Nitrogen helps the leaves and shoots grow quickly and without problems. Most fertilizers containing nitrogen are applied in spring, when the growing season is just beginning. It should be noted that in August and autumn, it is impossible to introduce substances containing nitrogen. This can interfere with the maturation of the plant's wood.

The most popular nitrogen-based fertilizers are:

• Urea. It consists of 46% pure nitrogen. Urea is used both foliar and root feeding grapes. Due to the large amount of nitrogen in the composition, it can only be applied several years after planting. In order not to harm the plant, you need to dilute up to fifty grams of fertilizer per liter of water and add it to the soil.
• Ammonium nitrate. It is best to use the substance during flowering. Fertilizing the grapes while pouring the berries is not recommended. This can affect the quality of the berries. Ammonium nitrate is best sprinkled on slightly damp soil around the bush.

Potash fertilizers for grapes

Potassium is another important trace element that is necessary for the full development of a plant. It accelerates the growth and ripening of the plant's berries. Nutrients consisting of potassium are great for feeding grapes in the fall, as such fertilizers prepare the plant well for cold weather.

Grapes are one of the most consumed crops. a large number of potassium from the soil, so you can feed the soil annually.

• Potassium sulfate. For good results, it is best to use this foliar application during the final stage of growth. The average amount of substance that will be needed is 20 grams per 10 liters of water; 40 grams of superphosphate must be added to the bucket. It neutralizes acidity.
• Potassium chloride. Contains 50% to 60% potassium. It is best to add lime to this fertilizer to neutralize acidity. Potassium Chloride can be used in tandem with any trace minerals and nutrients other than urea.

Phosphate fertilizers for grapes

Phosphorus is one of the three most essential components for garden crops... He - perfect solution for feeding young grapes on initial stages growth and flowering. Due to the phosphorus base, flowers and berries develop much faster and better.

• Superphosphate. Contains up to 20% phosphorus in its composition and gypsum. Suitable for all types of soils, however, acidic ones must first be lime or lime added to the fertilizer solution. You need to apply superphosphate after the beginning of flowering. This will help the fruit develop better during the ripening period.
• Double superphosphate. It consists of 50% phosphoric acid, but does not contain gypsum. It is used in the same way as simple superphosphate.

Complex and compound fertilizers

Complex nutrients consist of two or more elements.

• Azofoska. It is a combination of three main macronutrients: nitrogen, phosphorus and potassium. It is found in two types - dry and dissolved. The first one must be brought under the bush. The amount of the substance is up to sixty grams per plant. It can be used only during the warm season. The liquid form consists of two tablespoons of azofoska, diluted in one bucket of water, the solution must be poured under the root.
• Bischofite. A complex fertilizer containing magnesium, boron, iodine and bromine. In total, more than ten components. Used for foliar feeding of grapes. It is necessary to dissolve ten liters of water in 150 milliliters of bishal, but, in order not to damage the plant, the dosage can be reduced by almost half. This tool is used as a boron fertilization of grapes. In terms of quantity, this element in bischofite takes the second place, in the first place is magnesium.

Organic fertilization

Top dressing of grapes ash- perfect solution. It is best to use only woody ones. Ashes after burning coal are not used at all as fertilizer; they contain toxins that are harmful to plants.

The ash of the tree has a large amount of micronutrients that are beneficial for the plant. For example, magnesium, boron, potassium and phosphorus. It can be used as a soil acidity regulator.

Other organic fertilizer – bird droppings... It helps to almost double the fertility and speed up the ripening process for several weeks.

To understand how to feed grapes with chicken droppings, you need to remember important rule: before applying such a fertilizer, you need to prepare a special nutrient solution for the plant. Fresh droppings can irritate the soil and shoots.

For 20 liters of water, about 1 kilogram of droppings are needed, the solution must be infused for two weeks. Fertilizer should be applied at a short distance from the bush in small portions into holes, up to 35 centimeters deep. For full fertilization of the plant, two buckets are enough.

Folk remedies for fertilizing grapes

One of the most effective means- yeast feeding. The recipe is quite simple:

1. One gram of dry baker's yeast must be dissolved in one liter of slightly warmed water, add a teaspoon of sugar, mix thoroughly until completely dissolved. The mixture should be infused for a couple of hours. Before fertilizing plants, dilute one liter of the finished solution with five liters of clean water.
2. Dilute fifty grams of live yeast in a liter of slightly warmed water, let it brew a little. It is also necessary to dilute the fertilizer with five liters of water before watering.

Microfertilizers

In addition to the three main elements in the composition of nitrogen, phosphorus and potassium, for full growth and good yields, grapes also need other trace elements: boron, magnesium, zinc and others.

Microfertilizers are one of the most popular fertilizers. They exist great amount... For example, potassium magnesium, which contains 28% potassium, 18% magnesium and about 16% sulfur.

Microfertilizers also include copper fertilizers, which are used for foliar feeding.

One gram of the substance is enough to spray one bush. It should be brought in no more than once every four years.

Root dressing scheme for grapes

To properly feed, you need to know the dosage and timing. It is better to add less than randomly fill in useless and sometimes harmful substances.

Spring feeding of grapes is considered the most an important milestone... It helps bushes to recover from frost and stimulates fertility.

Top dressing methods

Separate root and foliar feeding. They differ in the way they are introduced. In the first case, nutrients need to be poured or placed under the bush for the best effect. The second can be considered an auxiliary stage. Foliar dressing helps the plant to develop correctly, stimulates the growth of shoots and ovaries, and increases yields.

Foliar dressing

If the grapes are planted in soil that is saturated with microelements, then for the first three years it does not need to be fertilized, since the plant will feed on substances from the soil. Foliar dressing contributes to the development and improvement of yields. The first time the leaves should be processed before flowering, the second time after flowering, the third time during the maturation of the brushes. Foliar dressing of grapes is carried out regardless of the amount and type of fertilizers that are applied to root system plants.

To know exactly how to feed the grapes, you need to start from the type of soil and the age of the plant. The most important elements are nitrogen, potassium and phosphorus. Almost all fertilizers contain them. Boron, magnesium, zinc and iodine are also needed for proper growth. Thanks to the ability to properly and timely feed the grapes, you can get juicy and tasty fruits.

Not only lovers of these fruits dream of their own vineyard, but also connoisseurs of wine drinks. However, it is one thing to plant grapes in July and forget about them, and quite another to figure out in more detail how to care for grapes in the summer, what techniques to use, and whether it can be sprayed. Master basic points, and your vineyard will grow actively, and caring for homemade grapes in spring and summer will be a joy.

A beginner should definitely learn how to properly care for grapes during the summer months. Find out what to do with the grapes in June, and you will soon be able to wait for the first fruits. Usually, summer care for grapes - both in the first year and in subsequent years, includes several basic procedures. This is pruning, and applying top dressing to the substrate, and spraying from pests. But in order for all these components to be performed correctly, care for young grapes must be carried out step by step.

All green operations

Competent care of grapes in summer will contribute to the active development of shrubs and the early ripening of fruits. To understand where exactly it is recommended to start, consider the following plant care requirements in June:

• it is necessary to control the intensity and direction of growth of foliage and the bush in general;
• a separate stage for the care of grapes - protection from pests and diseases;
• it is very important to create everything favorable conditions for shrub growth;
• it is also recommended to remove weeds and pinch stepchildren in a timely manner.

To take care of the grapes in June according to the rules, you should consider them in more detail.

Tying

Cultivation and proper care of grapes begins with the timely tying of shrubs. To do this, after planting the vines, the plants must be tied to a trellis. Thus, the direction of growth will be set correctly. When it is worth resorting to this procedure depends largely on the climatic characteristics of the region. For example, in regions where, as a rule, there are no frosts in April, it is possible to tie up grapes at this time. But in most of the central and northern regions of the country, it is better to start tying in June.

Wreckage

In order for the grapes to bear fruit in August, it is necessary Special attention to give a piece of old, weak or too thickening shoots. First, you will free the shrub from weak shoots, which are unlikely to properly form and ripen bunches of grapes. Secondly, you will be able to "adjust" the load on the branches of the bush. Remember: you can break off the processes if they have not yet reached 15–20 cm in length, otherwise you will only harm the plant.

Topping

Grape care in August often involves grafting the plant. For this, the cuttings must be prepared in advance. They are used in a lignified form. The essence of pinching is to have the old cuttings embedded in the shrub. Thus, you can significantly rejuvenate a grape bush that no longer bears fruit as it used to. It is desirable that each branch has at least two eyes.

Stepping

Breeding home vineyards is a responsible occupation, so you need to learn to pay attention to various little things. For example, greenery is often formed on a shrub, which does not affect the intensity of fruiting in any way. It is recommended to remove the stepchildren, which you can find in the axils of the leaves, as well as the mustache. Thus, all the energy of the bush will be directed towards the ripening of the bunches of grapes.

Chasing

Grape care in July and early August includes a procedure called chasing. It is recommended to cut the tops of the shoots to the first full-fledged leaf (after about the 15th). This procedure is necessary, because after it is carried out, the growth rate of the branches decreases, while more energy from the bush is spent on the fact that the fruits ripen sooner.

Winegrowers caring for young shrubs should take into account the fact that from time to time it is necessary to remove excess inflorescences and leaves on the plant.

Let's say no more than three weeks are left before harvesting. This means that it's time to start breaking off some of the leaves. First of all, tear off the leaf plates that have grown in the lower part of the shrub. Then remove from it those leaves that shade the bunches of grapes.

Top dressing and watering

The grapes grown on the site must also be fertilized on time and competently. The intensity of fruiting depends on this. Spraying grapes with liquid nutrients is not the best way out. As a rule, at a distance of 50–80 cm from the rhizome of the bush, a small hole or trench is dug, where additional fertilizing will be poured. It is better to divide this whole process into three key stages:

• at the beginning of spring, nitrogen mixtures and superphosphate are added to the soil. For top dressing to be effective, it is recommended to dilute fertilizers in water;
• before the beginning of the flowering phase, superphosphate, potassium and nitrogen mixtures are added to the substrate;
• when berries ripen on the bush in July-August, phosphorus and potassium dressing is applied to the soil.

Remember that it is necessary to water the shrubs as the ovaries appear. When the flowering phase begins or the harvest is nearing, irrigation of the vineyard should be stopped.

Disease and pest control

What you need to do with grapes to various diseases and the invasions of pests were not afraid of him? To do this, you need to find out how to spray the grapes. As a rule, most often the shrub suffers from fungal diseases. The use of store drugs will help you to prevent their appearance. Which formulations to buy depends on your preferences and cost. The main thing is that the medicines contain colloidal sulfur and copper.

As a preventive measure, try to regularly inspect the bunches of grapes. If the berries are blackened in places, cracked or began to rot, it is recommended to remove the bunches from the bush, as they can cause serious diseases. Grow grapes in Chuvashia, as well Rostov region or in Ukraine it can be very effective if you adhere to the basic recommendations for caring for it.

Video "Planting and caring for grapes"

In this video, you will learn how to plant and care for grapes.

Top dressing of grapes is a multi-stage process, covering the entire vegetative period of the vine. It is important to know how to feed the grapes, doses and timing. There are two types of grape feeding: root andfoliar.

Two weeks before flowering root feeding of grapes is required. If done correctly, this agrotechnical measure carrying out the shedding of ovaries from the bushes is significantly reduced. 10 days after flowering carry out one more top dressing.

Ripening grapes should be accompanied by another nutrition and already after harvest the last dressing is done to increase the frost resistance of the vine. Feeding alternates with watering.

Fertilization technology for grapes

Root compounds must be placed in the ground by deep excavation: the root system of the grape bush is located at a depth of 35 cm. The use of liquid dressings is effective.

Fertilizers

The leader in popularity is considered to be manure. Its advantages:

• Complete composition.
• Promotes loosening of the earth.
• Forms humus.
• Useful elements are assimilated in stages over 4 years as the manure decomposes in the soil.

Fertilizing grapes with organic

Natural fertilizer enriches the land in early autumn period, mixing with mineral compounds. Component ratio:

• Manure - 5 kg;
• Superphosphate - 100 g;
• Ash - 100 g;
• Ammonium sulfate - 50 g per 1m 2.

For better distribution of manure after application, you need to dig up the soil... This method of fertilizing grapes is used once for 3 years. The most valuable is strawyhorse dung.

Moreover, an exceptionally fresh composition is needed, since beetle larvae are always present in greenhouse manure, which can damage the root system of the bushes.

Fertilizer manure pits

They are formed in the spring. A hole is dug on equal distance between the bushes at a depth of 35 cm wide with a shovel. V

the resulting niche is placed a manure composition based on 1 part superphosphate and 10 parts fresh manure... The mixture should be buried and lightly tamped.

Slurry

Fresh cow dung is used. For a soil area of ​​1 m2, half a kilogram of manure is used. Manure must first ferment. To do this, it is placed in barrels, cemented pits in a diluted form (2 parts of water to 1 part of manure).

Before ripening, the fertilizer should be in a niche with a closed lid. The resulting slurry is diluted with water at the rate of 1 part of manure to 20 parts of water.

Under the bushes, pour ½ bucket per square meter area. The process is completed by watering the fertilized vineyard.

Calculation of the amount of fertilizers for feeding grapes

Bird droppings

It is characterized by the richest composition, but requires careful use. Overuse can “burn” the soil. The composition is prepared as follows: the droppings are diluted with water at the rate of 2 parts of water per part of the droppings and defended for 14 days. Then 100 g of slurry is diluted in a bucket and poured under shrubs per 1 m2.

The treated areas are watered. The use of poultry manure should not exceed 50 g of dry matter per square meter of area.

Top dressing of grapes with nitrogen fertilizers

Their role is to ensure maximum nitrogenous feeding of plants from the moment of root absorption of the composition from the soil.

Saltpeter or ammonium sulfate used in the calculation of 50 g of fertilizer per square meter. Autumn rains and winter snow distribute the composition evenly to the root areas of the vineyard.

Preparation of the solution

The first feeding of a square meter of vineyard will require 100 g superphosphate with 50 g nitrate... Superphosphate in containers is poured with water in the evening.

In the second and third feeding, saltpeter is replaced by ash (50 g of wood substance per m2). The process is completed by watering the vine.

How to water grapes

Water the grapes well before feeding them. Fifteen centimeter longitudinal grooves are dug. Their width is about 40 cm.

The depressions are filled with water (10-15 buckets for the bush). After absorbing the liquid, the ditches are filled with earth and loosened with a rake.

Periodicity: before flowering and during ripening bunches. Ideal conditions: cloudy weather or morning dew (nutrients are absorbed more efficiently). Grape leaves are sprayed with a superphosphate solution enriched with trace elements.

• Water - 10 liters;
• Superphosphate - 50g;
• Manganese 0 2g;
• Acidified iron - 5g;
• Sulfur zinc - 1 g;
• Borax - 2g.

Superphosphate is insisted in water for a day, stirring occasionally. The solution is poured, leaving the precipitate in the container. The remaining ingredients are placed in the liquid. She is sprayed with grape leaves, observing the conditions:

• avoid repeated contact of the solution to one area;
• direct the solution to the underside of the leaves (nutrition is better absorbed).

The use of nitrogenous compounds for the surface feeding of grapes is unacceptable: you can easily burn the leaves with nitrogen.

If the grower adheres to all the rules of agricultural technology and knows how and with what, a rich harvest is guaranteed in the fall.

Scientists have found that in the choice of soil, grapes are unpretentious, any, except for salt marshes and marshes, is suitable for it. For his own growth, he does not particularly need fertile land, he feels great both on rocky and sandy soil. But if we want to grow a vine that gives high yield, you will have to feed it throughout the growing season.

Menu for grapes

Grapes are woody perennial liana of the grape family. Shoots of grapes - vines - can reach a length of several meters. They are excellent climbers: clutching branches, partitions, ledges with their tenacious antennae, they easily climb onto tree crowns, gazebo roofs, arches and other buildings. Fruits - juicy berries of pleasant sweet and sour taste - are collected in an appetizing bunch.

The history of the emergence of grapes is rooted in the past for many millennia, and it does not matter who and when was the first to discover this wonderful creation of nature, it is important that it has come down to us, multiplied many times by wonderful varieties and pleases with the splendor of choice and taste.

Bunches of grapes, nurtured by the sun and caring hands, delight with great taste

"There is no greater pleasure in the world than to feel the fragrance of a blossoming vineyard ..."

Pliny the elder

Collection of quotes

Top dressing of grapes begins with the diapers. The planting pit is filled with a soil mixture well fertilized with organic matter and minerals in such a way that the young bush has enough nutrition for the next year or two. Introduced:

• 1-2 buckets of humus or rotted manure;
• 200 g superphosphate and 150 g potassium sulfate(or 1 liter of ash).

Then you can start root and foliar feeding. For good nutrition grape bushes use inorganic and organic fertilizers.

Mineral fertilizers

Inorganic, or mineral, fertilizers are:

Some of mineral fertilizers especially important for grapes.

Potassium

No matter how tasty we feed our grapes, if potassium is not on the menu, the vine will demand it, because potassium:

Azofoska is a complex fertilizer that includes the most important elements in needed by the plant proportions necessary for grapes for a good harvest and the life support of the bush:

Fertilizer is used in two ways:

• direct introduction of dry matter into the soil;
• pouring the solution to the roots along drain pipes or trenches.

Urea (carbamide) is one of the main nitrogen mineral fertilizers necessary for grapes, it contributes to:

Boron

Boron deficiency has Negative influence on the formation of grape pollen, which impairs the fertilization of the ovaries. Even a simple foliar dressing of grapes with boron before flowering can increase the yield by 20-25%. Boron and boron-containing substances:

• help the synthesis of nitrogenous compounds;
• increase the content of chlorophyll in the leaf;
• improve metabolic processes.

Important! An excess of boron is even more harmful than a deficiency, which means that when preparing a solution, it is necessary to carefully calculate the doses according to the instructions.

Boron deficiency leads to a deterioration in the formation of grape ovaries

Organic fertilizers

During the entire growing season, in addition to inorganic fertilizers, it is possible and necessary to feed the grapes with organic matter. Inorganic and organic fertilizers have their fans and opponents, therefore, dear reader, it is up to you and only you to decide what to give preference to. Or maybe find a middle ground - to use organics as "snacks" between the main dressings? Moreover, we have a wide choice.

Manure

It is a waste product livestock containing a lot of useful substances:

• nitrogen,
• potassium,
• phosphorus,
• calcium.

Horse manure is considered the best, followed by cow manure, or mullein... Before using this organic fertilizer, you need to let it peel (it goes to fertilize the soil around the bush) or prepare the infusion (for watering around the roots) in this way:

The grapes are fed with mullein infusion through drainage pipes or trenches once every two weeks, combined with watering.

Bird droppings are a product of the vital activity of birds, an equally valuable organic fertilizer. It can be composted or used as an infusion. The procedure for preparing the infusion:

Infusion of bird droppings is poured through drainage pipes or into trenches between the main dressings, combining with watering once every two weeks.

For feeding with manure and poultry manure infusions, we choose one thing or alternate so as not to overfeed the plant.

Wood ash

Wood ash is an ideal top dressing for grapes, it contains:

• approximately 10% magnesium and phosphorus;
• about 20% potassium;
• up to 40% calcium;
• sodium, magnesium, silicon.

When dry, it significantly improves both mechanical and chemical composition soil, alkalizing it. On heavy soils, ash is brought in for digging in autumn and spring, and on light sandy soils - only in spring. Application rate - 100-200 g per 1 sq. m.

It should be noted that simultaneously with nitrogen fertilizers ash is not used, as it promotes the "volatilization" of nitrogen, so for grapes we will apply foliar feeding with ash infusion. It is done like this:

1. Wood ash is poured with water in a 1: 2 ratio.
2. Insist for several days, stirring regularly.
3. Then it is filtered and added to each liter of the mother liquor 2 liters of water.

Ash infusion is sprayed on plants between the main dressings.

For grapes, foliar top dressing with ash infusion is used.

Eggshell

Eggshells are also organic fertilizers. It is almost entirely (94%) composed of calcium carbonate. Fertilizer is prepared from it as follows:

Use crushed eggshell for deoxidizing the soil around the grapes as needed at the rate of 0.5 kg of powder per 1 sq. m.

An excellent organic fertilizer is herbal infusion. To prepare it, you will need a large container. The infusion is made in this way:

The remains of the grass are laid in compost heap, after decomposition, it will make herbal compost, and the infusion is used for root and foliar dressing at the rate of 1 liter of infusion per 10 liters of water. Root dressing is combined with watering, foliar dressing is carried out between the main spraying on the leaf.

Yeast infusion

Yeast infusion will be a good addition to the grape menu. This fertilizer is completely safe for humans and plants. Yeast contains:

• Saccharomycete fungi,
• B vitamins,
• proteins,
• carbohydrates,
• trace elements.

To prepare the yeast infusion you need:

1. Pour bread crumbs into the bucket - about a quarter of the volume.
2. Add 2-3 tablespoons of sugar and 50 g of raw baker's yeast.
3. Cover with water, leaving room for fermentation.
4. Insist in warm place until you get bread kvass.

The working solution is made at the rate of 1 liter of infusion for 10 water. Top dressing is combined with watering.

Top dressing of grapes by timing

During the growing season, 7 dressings of grapes are carried out, of which two are foliar... Doses and timing of fertilization are shown in the table below.

Spring root dressing

As soon as the buds begin to swell on the vine, spring root feeding is carried out with a complex of mineral fertilizers, which includes:

• ammonium nitrate or urea,
• superphosphate,
• potassium salt.

Fertilization is necessary for grapes to replenish the supply of nutrients after a dormant period. All solutions of mineral fertilizers are made in accordance with the attached instructions. Feeding is carried out in this way:

Top dressing before flowering

The second time we feed the grapes in the third decade of May before the beginning of flowering at the root, using the same composition as for the first feeding, but with a lower dosage of fertilizers and per leaf. This will improve pollination, will contribute to the enlargement of the bunch.

Top dressing to improve the ripening of berries

The third time we apply fertilizer under the root, consisting of superphosphate and potassium salt, before ripening the berries, which will increase their sugar content, accelerate ripening. We do not add nitrogen to this top dressing, so that the vine has time to mature well and become woody... On small berries we carry out foliar spraying with a complex mineral fertilizer.

Superphosphate is used during the ripening of grapes

Fertilizing after harvest

After harvesting, the bushes must be fed with potassium sulfate and superphosphate to replenish the supply of nutrients and increase the plant's winter hardiness. In addition, once every 3 years in late autumn, humus or compost based on bird droppings, manure, plant residues is introduced into the hole for digging (at the rate of 1-2 buckets per square meter). This improves the chemical and mechanical composition of the soil.

Once every 3 years in late autumn, 1-2 buckets of humus are introduced into the hole for digging

Foliar dressing

In addition to root dressings, we carry out two foliar dressings, one 2-3 days before flowering, the other on small ovaries. Foliar dressing is carried out in dry, calm weather at sunset, so that the solution remains wet on the leaf longer. Plants can be treated during the day if it is cloudy.

Not all growers consider foliar dressing to be very effective, but they are in no hurry to abandon them, using it as an additional recharge in tank mixtures when treating a vineyard against various diseases.

What does foliar feeding give? I believe that when spraying a plant, nutrients are absorbed by the leaf in a few minutes, which means that the grapes will receive nutrition several times faster. This method is good for emergency treatment of a weakened bush.

Video: how and what to properly fertilize grapes

Top dressing of grapes - important element in the development of the bush and pledge good fruiting... Observe the processing times, apply fertilizers correctly, and the vine will certainly thank you with a generous harvest.
