FIELD: agriculture. ^ SUBSTANCE: proposed method involves cutting under soil and weeds at a given depth using cutting working elements, mainly in form of A-shares, packing the underlying soil layer using the said working elements and preliminary breaking of the soil. The soil is cut below the sowing level. Under the working elements on beds made by the blades, the main fertiliser doses are applied in bands. Subsoil compaction is done over the main fertiliser doses with preparation of the packed seed bed breaking up the soil on top of the seed bed and levelling the soil surface while throwing the said weeds onto it using multifunctional rollers. After that seeds are sown into the ground with or without starter fertiliser doses. The assembly has a frame with a connecting device, supporting wheels and a system for changing height of the frame above the soil. The cutting working elements mainly in form of A-shares, are held to the frame by posts. The posts are provided with devices for receiving and distributing fertiliser. The fertiliser application system has a storage tank, dosing and transportation elements. The assembly has multi-functional rollers linked to the frame, mounted after the working elements. The rollers have ring-shaped rims with spokes, located in the axial direction at a distance from each other at acute angles of attack. In the operating position, the bottom of the multi-functional rollers lies above the level of cutting edges of the working elements. The assembly also has a system for sowing seeds with or without starter fertiliser doses. The system for sowing seeds is provided with shares, located after the multi-functional rollers. ^ EFFECT: provision for application of main fertiliser doses when sowing and increased uniformity of sowing depth. ^ 9 cl, 3 dwg |
