FIELD: agriculture.
SUBSTANCE: device for harvesting grain crops and disposal of tailings comprises a hopper for harvest, a system for supplying a solution of nitrogen fertilisers, pneumatic slit sprayers, and a tank for solution. The pneumatic slit sprayers are arranged above the straw chopper and mounted on a common axis with the possibility of their displacement together with the axis on height and horizontally on it to provide overlapping the spray patterns. The tailings are chopped, treated with a solution of nitrogen fertiliser and scattered across the field.
EFFECT: increase in soil fertility.
