Mandradzhiev, S. (Agraren Universitet, Plovdiv (Bulgaria))
It is known, that theoretical research of soil layer turning has been based on constant soil density. Actually, soil density varies with depth. Mathematical relations been derived for the angle of additional rotation of soil layer, gravity center displasement factor of the layer, and the tilling depth for high quality plowing with variable soil density.
