The purpose of research is to establish the parameters of the content of nutrients in the main and by-products of crops depending on fertilizer and liming. Research methods are generally accepted for inpatient research. The scientific novelty is that the parameters of the content of nutrients in the main and by-products of crops will be the basis for calculating the updated standards of nutrient removal. As a result of scientific research, the standards for the removal of nutrients by crop products depending on agrotechnologies for the use of fertilizers and limestone reclamation in the crop rotation of Western Polissya on sod-podzolic soil based on the following conclusions: Mineral fertilizer and chemical reclamation have significantly changed the basic physical and chemical properties of sod-podzolic cohesive sandy soil. In particular, the cultivation of crops without fertilizers and with the use of mineral fertilizer system causes their acidification: after eight years, the pHCl index gradually decreased by 0.25-0.67 units, hydrolytic acidity increased by 0.35-0.88 mg-eq / 100 g of soil. With the application of 1.5 doses of dolomite flour against the background of mineral fertilizers, the physicochemical properties of the arable layer of the soil were maintained in ranges close to optimal, which neutralized the soil acidity, which remained close to neutral with pH 5Cl for 5 years after chemical ameliorant application. , 65 and Hr 1.57 mg-eq./100 g of soil. Fertilization and liming had a positive effect on the nutrient regime of sod-podzolic soil. In particular, the application of 1.5 doses of dolomite flour on the background of the mineral fertilizer system increased the content of mobile phosphorus compounds to 264.6 mg / kg of soil (high level of supply), which is 49.0 mg / kg of soil more than   Product Description popup.authors Huk Bogdan V.
