In course of the research there was studied the influence of drainage and improvement on agrochemical properties of mineral soils. The research was realized in the conditions of the Republic of Belarus in Vitebsk Experimental Station for Land Reclamation. As a result of the research it was examined the results of surveys of the drainage effect and long-term cultivation on agrochemical properties of soils in conditions of Belarusian lakes area. It was determined that drainage of area improved power plants with nitrogen, phosphorus and potassium. Soil moisture, on the contrary, led to the accumulation of phosphorus and retrogradation of fixed potassium. Despite of 29 years usage of fertilizers and putting them more than 1.700 kg/ha of P2O5, it was not observed in the sod-gley soil an excessive accumulation of heavy metals. As far as grass fodder had unfavorable ratio between potassium and sodium it was recommended to improve the fertilizers system.
