FIELD: agricultural engineering, in particular, pre-sowing local strip application of fertilizers. ^ SUBSTANCE: apparatus has single-disk shank comprising carrier-casing, flat disk, seed guide, fertilizer guide, protecting shield with window and shoe. Fertilizer guide is mounted on single disk shank and is provided with mineral fertilizer divider positioned immediately after protecting shield. Divider is made in the form of cone having certain angle at its apex. Divider cone apex is positioned strictly in plane of symmetry of fertilizer guide. Seed guide is made in the form of two branch pipes, each positioned on individual single disk shank. Single disk shanks are positioned so as to allow regulation of depth and width of apparatus stroke independently from one another within wide range of depths and widths. ^ EFFECT: increased efficiency in utilization of mineral fertilizers by introducing main dose of mineral fertilizers during sowing aside and below planting material and provision for tight contacting of fertilizers with soil. ^ 5 dwg |
