Even on rich soil, the yield of bushes decreases with time, the feeding of grapes in the spring is a necessary operation, helping to compensate the annual need of the plant for useful elements. For an important event to bring success, you need to understand what substances are needed for this culture in the initial phase of development.
How to feed grapes in the spring?
A good harvest of a solar vine is only possible for a vine grower who will be able to organize the nutrition processes of its fruit-bearing bushes competently. Spring feeding of grapes is the most important agrotechnical measure, mistakes in which are unacceptable. Beginners planning to purchase mineral fertilizers should understand the list of useful substances needed for growing shrubs:
- Nitrogen - helps to increase the necessary amount of green mass.
- Phosphorus - is required in large quantities during flowering and tying full-bodied berries on the bushes.
- Potassium - is required for photosynthesis and cell laying, for normal adaptation of grapes to the cold.
- Boron - feeding the grape in spring this element is needed to stimulate the germination of pollen, maturation, improve sugar content.
- Copper - strengthens the growth of the vegetative mass, increases the plant's drought resistance and cold resistance.
- Zinc - affects nitrogen exchange and vine yield.
Feeding of grapes in spring with mineral fertilizers
The necessary mineral fertilizers for grapes in the spring are required to be introduced from the very moment of opening the bushes, so that by the time of bud blossoming they have dissolved and reached the root system. There are several options for how to effectively administer nutrient vines:
- Watering the land near the grape with a solution of fertilizers.
- Injection of mineral fertilizers together with organics into grooves.
- The introduction of liquid dressings into special pipes for the rapid delivery of useful substances directly to the roots.
- Spring foliar top dressing.
Nitrogen fertilizers for grapes
Often with this goal, wine growers use popular nitrate or ammonium sulphate. The effectiveness of this measure increases if superphosphate is added together with nitrogen. The last fertilizer is recommended to be filled with water from the evening so that it can properly dissolve. The first application uses 50 g of saltpeter and up to 100 g of superphosphate. Another good kind of nitrogen fertilizing is urea.
Feeding grapes in spring urea:
- The first time - is made on the eve of discovery in the trenches, dug ahead of time in the trunk circle. 40 g of carbamide, 40 g of phosphorus fertilizer and 30 g of potassium fertilizer are used.
- The next fertilization with the carbamide of grapes in the spring is required at the end of May, produced together with potassium and phosphorus in the same ratio.
Potassium fertilizers for grapes
Potash fertilizers can be delivered in different forms to retail chains, so you should carefully study the labels. For example, potassium chloride can reduce the overall increase in vines, and potassium sulfate and potassium phosphate together with nitrogen-containing top dressing increase the growth of the green part of the bushes. This substance for grapes should be introduced in the season up to 4 times - after opening, before flowering, at the time of active fruiting, at the end of ripening of grapes.
Potash fertilizers for grapevines:
- Potassium chloride - in the spring on vineyards do not recommend.
- Potassium sulphate is simple in transportation and storage, it brings tangible benefits in the feeding.
- Kalimagnesia fertilization is recommended for grapes on light soils, besides potassium it contains valuable magnesium.
- Oven ash - has a natural origin, harmless, potassium oxide can contain up to 14%.
Complex fertilizer for grapes
The use of combined fertilizers makes it easier to care for shrubs, reduces storage costs, the introduction of useful elements occurs more quickly and the effectiveness of their impact on the vine increases. Spring root feeding of grapes will give the best result if the soil analysis is performed the day before, in order to more accurately calculate the concentration of the drug used in the work.
Varieties of popular complex fertilizers:
- Ammophos - 10% N and 45% P.
- Diammophos - 21% N and 53% P.
- Ammonium polyphosphate is 23% N and 67% P.
- Potassium nitrate - 14% N and 46.5% K.
- Nitrofosca - up to 16% N, up to 16% P and up to 16% K.
- Metaphosphate of potassium - up to 60% P and 40% K.
- Nitroammophoska - 18% N, 18% K, 18% P.
How to feed grapes in spring with folk remedies?
Folk remedies can effectively support the growth of bushes, if used in the right proportion and at the most appropriate time. Often used in suburban areas manure, ash, mulch , herbal infusion, peat, compost, litter of birds, popularity is gained by siderates. Feeding organic grapes has its pros and cons, which should always be taken into account in the work.
Advantages of feeding in spring organic on the vineyard:
- Organic fertilizers are obtained from constantly replenished wastes of livestock or crop production, so their use in the presence of subsidiary farming is almost free.
- Useful substances in these top dressings are contained in the most readily available form.
- Organic fertilizing positively affects the structure of the soil.
Minuses of applying organic fertilizing for grape in spring:
- It is difficult to control the required dose of mineral matter.
- The given feeding is connected with the raised risk of introduction on a vineyard of larvae of wreckers, weeds and pathological disputes.
Feeding grapes in spring chicken droppings
Correctly produced grapes fertilization with chicken broth will help saturate the soil with a full set of useful substances, but the application of this natural fertilizer should be done as carefully as possible so as not to burn the plant. The recipe for preparing a nutritious organic composition is simple:
- Dilute in a suitable container litter water in the proportion of 1: 2.
- The solution is infused for up to 2 weeks.
- To fertilize the grape in the spring, the fertilizer obtained is bred with clean water 1:10.
- Buckets ready solution is enough to water 1 m² of soil.
Grape feeding with ashes
The ash contains a rich set of substances - up to 40% calcium, 10% phosphorus, about 20% potassium, magnesium and other trace elements. The fertilization of grapes with fly ash can be done in several ways:
- Insertion of dry ash into the holes near the barrel up to 2 kg per adult bush.
- Foliar top dressing with ash infusion - microfertilizer is poured in buckets with water 1: 2 and further insisted for up to 3 days, before use, the preparation is carefully filtered.
- For watering the vineyard - 1 liter of ash diluted with 3 liters of water, infusion is produced 24 hours, then diluted with water to 10 liters.
