How to pour fertilizer for grapes

Grape – culture is special. For the successful fruiting of complex fertilizers is not enough. The need for various nutrients in grapes depends on the growing season.

The grapes are greatly depletes the soil. And for the fruiting of the vine need fertile soil, rich in nutrients and trace elements. For those who want to achieve success in viticulture, it is necessary to study vegetation phases and to understand what fertilizer at what time the necessary plant.

Nitrogen

Nitrogen is introduced in the form of ammonium nitrate or urea. This substance helps to shape the leaf mass and shoots. Nitrogen fertilizer is necessary to make in the spring, at the beginning of the growing season. In summer, the nitrogen demand is not so large, and in the fall it is generally harmful to the plant because of the rapid formation of green mass of the wood does not ripen in the winter and may be killed by frost.

Phosphorus

This element is necessary for good flowering. Therefore it is to be paid at the beginning of flowering in the form of superphosphate. Due to the phosphorus inflorescence is better developed, the berries tied and bunches ripen faster.

Potassium

Potassium is necessary for the grapes in the fall. It speeds up ripening and at the end of the fruiting prepares the vines for the winter. Introduced in the autumn in the form of potassium chloride. Even better to use instead of ash, because in addition to the required potassium potassium chloride contains chlorine, which in excessive amounts may harm the vineyard. You can make ordinary wood ash, fit that which is left over from a barbecue or burning autumn debris. Ash will ensure the grapes are not only potassium, but also phosphorus.

Copper

Copper is also stored in the fall, but after potassium, closer to winter, in the form of copper sulfate. Accelerates the lignification of shoots, increases frost and drought tolerance.

Boron and zinc

Thanks to these two elements, the sugar content of grapes increases, the yield increases and bunches ripen faster. Need to make before active ripening in the form of boric acid and zinc sulfate.

Organic fertilizer

Mineral elements in grapes enough. For good fruiting him the necessary organic matter. It not only provides an opportunity to develop useful microorganisms in the soil and improves its aeration, which promotes better assimilation of mineral trace elements. It is best to use poultry manure. It contains all the necessary grapes substances, and in a digestible form.

If no bird droppings, you can use the compost. Compost is easy to prepare independently, erecting on the site a compost pit and folding back the food and plant waste.
