ABSTRACT:
A seed drill has a frame, reservoirs, sowing shares, at least two separate inlets and outlets for two different materials, and a depth-guide or pressure roller behind each sowing share. Variable amounts of one material are conveyed to the forward outlet and of the other material to the rear outlet through separate conductors inside the sowing shares for application of the soil. The outlets are separated along the direction of travel. There is a narrow ripping structure on the forward edge of each sowing share to rip up the soil and produce a furrow. An expansion structure that extends down into the furrow is positioned in the vicinity of the rear outlet of each sowing share. The expansion structure is at least somewhat wider than the ripping structure. The bottom end of the expansion structure is higher than the bottom of the point of the ripping structure.
