METHOD AND APPARATUS FOR EROSION-PREVENTIVE AUTUMN TILLAGE OF SOIL Russian patent published in 2005 - IPC

FIELD: agricultural engineering.

SUBSTANCE: method involves shallow plowing, deep basic tillage and surface tillage (cultivation) of soil by cutting furrows; after harvesting of cereals, performing simultaneously shallow plowing, surface tillage of soil to depth of up to 16 cm, crushing of soil lumps, compacting, leveling and mulching of soil top layer; in September, providing deep tillage of soil on fields arranged on slopes with gradient exceeding 5 deg while forming vertical slits to depth of 40 cm and inclined slits; simultaneously with slitting procedure, forming water-accumulating vessels, holes and intermittent furrows. Apparatus has hitch, carrier wheels, bearing system and replaceable working tools in the form of disk batteries, flat narrow hoes, rippers with chisel, ring-and-serrated roller, and leveling drum. Blades of leveling drum are arranged at an angle α=30 deg relative to drum axis.

EFFECT: reduced soil erosion and provision for retention of moisture in soil root layer.
