Object of study - soil formation processes, physicochemical and agrochemical properties, content of available compounds Ca2+, Mg2+, N, P2O5, K2O in the soil under conditions of different agrochemical load in the agrocenosis. Results of the study - In the conditions of the Right-Bank Forest-Steppe, it was determined that the nutritional regime of grey forest soil in the agrocenosis is mainly improved by the use of optimised doses of NPK against the background of reclamation action (3-5 years) of limestone materials in the amount of 2.5-7.5 t/ha: the degree of provision of nitrogen compounds increased by 18-27 mg/kg of soil, mobile phosphorus and potassium compounds by 52-64 mg/kg and 22-38 mg/kg of soil, respectively. When applying higher doses of mineral fertilisers, it was found that a one-and-a-half dose of Omya Calciprill granular meliorant significantly exceeded the effectiveness of a single dose, with a 22-27% increase in crop yields.
