Abstract

A drill for applying seed and fertilizer, with a frame, reservoirs, sowing shares with at least two separate inlets for seed and fertilizer, and a depth-adjustment or pressure roller mounted behind each share, in which the materials to be applied are conveyed in controlled amounts to the shares for application into the soil, in which the shares are connected to the frame with parallelogrammatic mounts and the depth to which the penetrate into the soil can be adjusted by means of a setting device. The drill can be used for zero tillage even on rocky soil to apply seed and fertilizer separately because the sowing share is a chisel share on which a chisel is mounted on the side facing the direction of travel. The chisel share has separate guides for seed and fertilizer inside its body. The outlets for these guides are separated in the direction of travel by a certain distance with the first outlet positioned as close as possible behind the chisel point. The chisel point extends deeper into the soil than the two outlets.
