Tillage is the mechanical influence on soil aimed on its fertility increase. Different tillage systems change soil structure, improve water, air and heat regimes of the soil. Selection of the tillage system is determined by climatic conditions and biological peculiarities of the plants. Soil packing is one of soil cultivation methods aimed on prolongation of soil durability. Main parameters of a smooth roller are substantiated. The role of the roller in the process of reconstruction of 'capillary network' of soil is analyzed. Schemes of binding of soil parts by the roller are presented. Schemes of ridging of soil parts by the roller are shown. Changes of a shrinkage factor on the definite depth are calculated. Dependence of resistance of overrolling movement on the roller's weight is displayed. Different types of rollers are analyzed and various types of them are suggested for different soil conditions.
