FIELD: agriculture.

SUBSTANCE: meliorative deep tiller-firtiliser contains a wedge-shaped rack (2). A fertiliser funnel (3) is mounted on the rear side of the rack. A ploughshare (4) is installed at the bottom in transit of the rack. A vertical disc knife (15) is installed in front of the rack. The ploughshare is mounted to the shoe (5) with a cone angle ensuring slickensiding of soil and plant residues. The cone angle is equal to γ= 60-80° depending on the type of soil. Loosening drums (11) with exchangeable teeth (12) are mounted behind the fertiliser funnel using brackets (10) at an angle to the motion direction reverse to the cone angle of the ploughshare. The brackets are fixed to the side wall of the rack. The teeth are made in the form of a quadrangular pyramid and are arranged in the rotation direction of the loosening drums with ribs. The teeth are placed on the lateral surface of the drums in a staggered order. The brackets are fixed to the frame by compression springs (13). The height of the teeth of the loosening drums is equal to the required depth of seeding down of the sown culture and is equal to 8-10 centimeters. The front part of the wedge-shaped rack is made along the radius of the disk knife rounding and has a sharpening angle of 10-15°. A chisel subsoil cultivator (18) is attached to the shoe in the lower part of the rack. Fertiliser distributing groove (19) is made in the rear part of the chisel subsoil cultivator. The groove is hermetically connected to the fertiliser funnel.
