What forms of use of mineral fertilizers for fruit crops, values, unlike the berries, has not.In years with unfavorable for the development of plant conditions (freezing of the root and aerial systems, weak growth, strong defeat leaves pests and diseases), as well as a very high yield it is advisable to spend the summer spraying plants (Table.) Solution makroudobreny - nitrogen, phosphorus, potassium,magnesium.

foliar microfertilizers(Bourne, zinc, copper and others.) as a rule, the main way to make them.The need for these can occur on any soil unbalanced introduction of macronutrients, and insufficient use of organic fertilizers.

To eliminate micronutrient deficiencies should undertake appropriate fertilizer solutions.Since the concentration of the solution is low and the effect of short-term, it is necessary to achieve the effect of repeated spraying.They carried out before flowering and after it - during the formation of the harvest intervals for 10-12 days.Feeding can be combined with a sprinkle of proshv plant pests and diseases.In the spring, on young leaves, it is necessary to process the weaker solutions than in summer.Foliar application should be done in calm, dry weather, it is best early in the morning or in the evening, that the solution to the leaves did not flush and drying out quickly.The positive effect on the development of fruit and berry crops have also feeding local fertilizers (see Table.).

berries are not particularly demanding of the forms of nitrogen and phosphate fertilizers.However, please note that on limed soils, ammonium sulfate are particularly suitable, sodium sulfate, ammonium chloride, ammonium, urea;neizvestkovannyh on acid - sodium and calcium nitrate, calcium cyanamide.

When using potash should bear in mind the ratio of berries to chlorine, which is a part of some potash fat.

very sensitive to it red currants, raspberries, strawberries.Therefore, a fertilizer with a high content of chlorine - sylvinite, carnalite Cain - can not be used under these crops.Most are suitable for all forms of chlorine-free berry crops - potassium sulphate, Kalimag, potassium carbonate, or potash, potassium-magnesium.Potassium chloride is better to make in the fall and in the spring of chlorine precipitation will wash out of root layer of soil.On light soils with low magnesium content should be preferred magnesium-containing potash fertilizers - potassium, magnesium, Kalimag, especially in crops demanding for magnesium (eg, raspberry).

restrictions on the use of complex forms of fertilizers for berries not, but it should be noted that the tuki containing nitrogen in the nitrate form (nitrofos, nitroammophos, nitrophosphate, NPK), you can not make the fall as nitrate nitrogen is lost.

complex fertilizers containing nitrogen in the ammonium form (ammophos, ammophoska, diammonium phosphate) in loamy and clay soils can be made, and in the late autumn.On light soils of all forms of compound fertilizers need to make in the spring.
