Development of multistage plowing method that involves subsurface loosening

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