SUBSTANTIATION OF THE CONSTRUCTIVE AND TECHNOLOGICAL SCHEME OF THE MACHINE FOR INTRA SOIL DIFFERENTIATED THREE-LAYER INTRODUCTION OF MINERAL FERTILIZERS
The necessity of accurate placement of the required quantity of nutritious elements concerning root system of plants presupposes intra soil layer-by-layer introduction of the differentiated doses of fertilizers on different depths. Meanwhile, phosphoric fertilizers have to be located in a horizontal tape closer to seeds in the moist layer of the soil, the centers of nitrogen fertilizers should be at different depths that will allow roots of plants to get necessary mineral nutrition during different vegetative periods. For providing adequate nutrition of plants during the whole vegetative period a new technology of the intra soil differentiated three-layer introduction of mineral fertilizers is offered and its constructive and technological scheme is substantiated.
