abstract A theoretical model was developed to predict soil clod size distribution attained after tillage so that it can be taken as initial state of soil for following erosion processes. The model was developed previously for rocks. The model predicts soil fragmentation resulting from multiple crack formation due to statistically uniform stresses. Peculiarities inherent to soils in view of their plastic properties are discussed. Comparison between calculated results and published experimental data demonstrates a satisfactory agreement.
