FIELD: agricultural engineering, in particular, subsurface application of liquid fertilizers during soil cultivation. ^ SUBSTANCE: apparatus has liquid tank, filters, pump with distributor, pressure pipeline, splitters, drain pipeline, hydraulic mixer, sectioned pipelines, and cultivator hoes fixed with their shanks to tines. Each sectioned pipeline is equipped with vertical branch pipes fixed on tines. Liquid flow splitters are joined to feed pipeline secured to lower part of tine and hoe shank. Flow divider is fixed at other end of feed pipeline, in mid portion of cultivator hoe chest. Outlet nozzles of flow divider cooperate with inclined fertilizer application devices equipped with apertures arranged in spiral path on said devices. Aperture first from flow divider is directed upward and following apertures are directed toward hoe cutting edge. Spiral pitch is twice the length of fertilizer application device. Feed pipeline is curved along line formed as cycloid. ^ EFFECT: enhanced reliability in operation, increased efficiency, simplified construction and convenient operation. ^ 5 dwg |
