The change in agrochemical parameters of light gray forest soil from the level of mineral nutrition against the background of the aftereffect of liming in the conditions of the Nizhny Novgorod region

Relevance. The modern level of agricultural production is inconceivable without the use of chemicals: lime, mineral fertilizers. Liming acidic soils with the introduction of mineral fertilizers are important methods of complex land reclamation. Excessive acidity of the medium is one of the main reasons for low productivity of agricultural crops.
Methods. The research was carried out in a long-term stationary experiment in the Nizhny Novgorod region on light gray forest soil. The influence of various doses of mineral fertilizers on the background of lime aftereffect on the productivity of the crop rotation link and changes in the acidity and degree of saturation of the soil bases were studied. The experience was based on a two-factor scheme.
Results. The article says that by 2022, the aftereffects of various studied lime doses do not affect changes in the level of productivity of fodder crops of the crop rotation link: vicа-oats (vicоoats) + clover — clover 1 g. p. — clover 2 g. p. — clover 3 g. р. The total productivity is 19.6–20.8 t/ha by the factor of lime application in 1978. The greatest productivity of the studied crop rotation link is provided by triple doses of mineral fertilizers (24.4 t/ha by the standard), double and single doses provide the level of productivity of the crop rotation link in 20.0–20.1 t/ha by the standard, the cultivation of forage crops according to the natural agrophone provides a productivity level of 17.2 t/ha k. е.
The applied lime doses, when laying the experiment, by 2022 do not affect the changes in agrochemical (exchange, hydrolytic density and the degree of saturation of the soil with bases) indicators in the twenty-centimeter soil layers. The use of triple and double doses of mineral fertilizers contributes to acidifying the soil compared to options without the use of mineral fertilizers and single doses.
