METHOD OF LOOSENING PLANTED SOIL Russian patent published in 2015 - IPC A01B1/00 A01D9/00 

FIELD: agriculture.

SUBSTANCE: prior to work, the planted soil is watered with moisture to a depth of 20÷25 cm. Pairwise using the linkage shovels of Lamerdonov after the embedding of their working bodies to the soil by operator feet with the force applied with hands down on the shovel handles, a fragment of the soil is lifted up, loosened and, without disturbing the root system of plants, are lowered to the place. Then using the return spring of the shovels the working bodies are extracted from the soil and transferred to the next working position, at that the rods of the working bodies are curved and have a concave shape which is described by the equation , where x, y is the abscissa and the ordinate, respectively, of the generatrix curve in a Cartesian coordinate system; j is the final rotation angle of the tangent to the generatrix curve, j <90°; L is the projection of the rod on the x axis.

EFFECT: improved water-air regime and increase in the efficiency of anti-erosion protection of planted soil.
