The article is devoted to the influence of both land properties and cultivation technologies on soil adherence to potato (Solanum tuberosum) plants. Compacted soil during further cultivation has the inadequate frictional structure with prevalent small parts in it. In the article authors shows that Rozin-Rammler's equation parameters may serve as criteria of soil adherence to the potatoes. Research results showed that soil adherence to potato rendered influence on ground drive system pressure and soil physical and mechanical properties. Compacted soil at the further treatment had unsatisfactory fractional composition in which there were prevailing small particles. Increasing of soil particle size led to increasing of soil adherence to potato tubers. For the soils with the optimal particle size the parameters of the Rozin-Rammler's equation had the following indexes: index of particle homogeny - n= 2-4; index of fineness - d(sub e) = 5-6 mm. For the modern technologies of soil treatment at potato growing the particle composition of soil was characterized by the following indexes of the Rozin-Rammler's equation: n=0,7-0,8; d(sub e) =12-23 mm.
