In a note recommendations concerning carrying out early-spring nitric top dressing of winter crops are made.
The high effect from early-spring nitric top dressing speaks that the winter get under way in growth early in the spring and at this time especially need nitrogen which in the autumn and in the spring is washed away from a korneobitayemy layer, and its accumulation because of depression of microbiological process owing to low temperature occurs poorly.
Therefore, the carry out in the spring top dressing winter nitric fertilizers, the lower it efficiency as with temperature increase mobilization of nitrogen of the soil by microorganisms amplifies later.
In due time carried out top dressing winter nitric fertilizers strengthens growth of plants, the water collecting in the soil for the autumn and spring period as a result is more intensively used. Besides, early-spring top dressing by nitrogen allows winter better to use nutrients of the soil and introduced before fertilizer.
