Tillage exposes the soil to different mechanisms of mechanical decomposition, which crucially change its structure. Possible approach in the controlling the quality of each specified operation and complete tillage process assumes establishing the functional relations between the operational parameters of applied mechanization and resulting mass probability density function of soil particle size. Based on experimental data from three independent experiments, the appropriate nonlinear relationships between the mass probability density functions of different soil fractions and particle diameters of these fractions. Calculations are based on the least squares fitting method. These expressions can facilitate modeling and prediction of soil fractions distribution and tillage quality control.
