UNIT FOR LAYER-BY-LAYER INTRODUCTION OF MODIFIERS INTO SOIL Russian patent published in 2020 - IPC A01B79/02 

FIELD: soil reclamation.

SUBSTANCE: invention relates to reclamation of eluvial soils under field conditions. Unit includes frame made of side members rigidly interconnected by cross beams, installed on support wheels with possibility of hanging to traction device, fertilizer reservoir located above the frame, connected to the fertilizer supply means to the soil, a working section containing a row of working elements fixed to the transverse frame beams, and a packing roller installed after the working elements along the movement of the unit. Unit contains the second working section, at the same time as the working elements in the first section the multicomplex plow is installed, and in the second section – shovel plows. Unit is equipped with unloading device providing transfer of weight load to soil from container with fertilizer at change of its weight as a result of fertilizer consumption. Means for feeding fertilizer into soil are high pressure hoses with nozzles fixed in working sections between working members and rollers. With such implementation, formation of a layer of structural soil from eluvial soils, sufficient for cultivation of crops with a deep root system is provided, layer-by-layer introduction of fertilizers, for example, humates or peat-gel, into soil, with its further compaction.

EFFECT: as a result of application of proposed unit it becomes possible to perform soil treatment at higher soil moisture content, for example, in early spring, at excessive moisture content, when use of other tillage equipment is still difficult or inefficient.
