The paper presents the results of the experiments on studying the influence of sapropel of Pribylovichi lake on agrochemical properties of sod-podzolic sandy loam soil of Lelchitsy region of Gomel region of the Republic of Belarus and the yield of crops. It is shown that application of organic-lime sapropel in doses of 30 and 60 t/ha and organic-siliceous one in doses of 60 and 80 t/ha increases the content of mineral forms of nitrogen in soil, the content of mobile forms of phosphorus and potassium in comparison with control variant (basic technology) and reduces its pH value, that allows increasing the yield of crops up to the level of 14–24 % depending on the crop to be cultivated and on the dose of sapropel application.
