FIELD: agricultural production, in particular, method which may be used for application of basic mineral fertilizer on sloped land. ^ SUBSTANCE: method involves providing presowing tillage to seed embedding depth; embedding seeds; providing line drilling of winter cereal crops and applying basic fertilizer in the form of vertical tape, said fertilizer tape being arranged between and below seed rows; as gradient angle of field increases, increasing depth of arrangement of fertilizer tape relative to seed rows. Apparatus has A-hoe, seed guides, fertilizer share, wedge, and safety valves. Depth of arrangement of fertilizer tape and tillage depth are adjusted by regulating height of arrangement of shank. Such method and apparatus allow the risk of washing away of fertilizers from slope to be reduced and depth of applying mineral fertilizer on each portion of field to be individually regulated depending on steepness of slope. ^ EFFECT: increased efficiency and simplified method and construction of apparatus. ^ 3 cl, 4 dwg, 3 tbl |
