METHOD FOR PREPARING DISTURBED AND DESERT LANDS FOR BIOLOGICAL RECLAMATION AND/OR UTILIZATION OF ANIMAL WASTE Russian patent published in 2022 - IPC E21C41/32 A01B79/02 

FIELD: agriculture, ecology and mining.

SUBSTANCE: invention relates to the field of reclamation of disturbed and desert lands with flat relief and can be used in agriculture, ecology and mining in the organization of reclamation and/or disposal of liquid organic waste from livestock enterprises. Namely: on agricultural fields with a humus content of less than 2.4% and a strongly pronounced plow pan, mining tailings, old abandoned filtration fields. The method includes two cycles, each of which consists of laying trenches to the depth of the subsoil and parent rock boundary, filling the trenches with liquid animal waste, mulching, forming over-trench ridges, compacting and leveling. The laying of trenches and all subsequent operations are carried out sequentially until the entire area of ​​the recultivated area is completely covered, after which a second cycle of the same operations is carried out, in which the trenches are laid in a direction perpendicular to the trenches of the first cycle. To implement the method, using a trencher, parallel trenches are torn to a depth of soil thickness to the soil layer - the border of the subsoil and the parent rock, on average from 0.5 to 1.5 m.

EFFECT: invention makes it possible to recultivate deserted and disturbed lands.
