Development of multistage plowing method that involves subsurface loosening

Abstract

The paper proposes a new method for multistage plowing that implies loosening bottom soil and subsoil horizon simultaneously, followed by overturning the bottom soil without cutting, which improves the quality of soil cultivation, softens a plow sole and reduces energy costs. Experimental studies confirmed the theoretical relationship for determining the plowing resistance, both of certain working bodies of a section, and of a whole plow. The method proposed for multistage plowing that implies loosening the subsoil provides a decrease in plowing resistance by 8.3-9.8% compared to the existing double-depth plowing followed by loosening the subsoil.

Theoretical justification of the parameters of the device for vertical measurement of soil hardness

“…When evaluating tillage machines, one of the important places is occupied by agrotechnical assessment of the quality of the technological process -tillage, and includes the determination of indicators of the state of the soil before processing, as well as indicators of the quality of the technological process, determined on already treated soil [1][2][3].…”
