MECHANICAL AND TECHNOLOGICAL BASIS OF DISCRIMINATORY APPLICATION OF MINERAL FERTILIZERS IN THE SYSTEM OF PRECISION AGRICULTURE

Theoretical and practical bases of technological and technical solutions of the problem of differentiated intra soil introduction of mineral fertilizers in the conditions of Northern Kazakhstan are given in work. The research results are implemented in cultivator- fertilizer prototype, are checked in laboratory and field conditions. Discriminatory application of mineral fertilizers taking into account key parameters of fertility of the soil will allow to provide saving of mineral fertilizers for 25-30%. Annual economic effect of implementation of the developed cultivator-fertilizer of machines makes more than 8 thousand dollars of the USA.
