Abstract 

The process of molecular diffusion penetration of components of mineral fertilizers into the soil was considered, as one of the possible ways of soil and groundwater pollution. Four mathematical models of migration of nitrogen fertilizers have been developed taking into account the adsorption of fertilizer components by the root system of plants and environmental conditions. Experimental investigations of the penetration of nitrogen fertilizer components have been carried out, on the basis of which the coefficient of molecular diffusion in sandy soils was calculated
