Баланс гумусу і елементів живлення у ґрунтах ТОВ «Горизонт» Богодухівського району Харківської області

Abstract

The balance of humus and nutrients in the soils of the farm "Horizon" LLC in Bohodukhiv district of Kharkiv region was calculated. The balance of humus in the soils of the first field crop rotation is positive - +0.191 t/ha, so no additional doses of organic fertilizers are planned. Having analyzed the balance of nutrients in the first field crop rotation, we can note that the balance of nitrogen and phosphorus in the soil is positive, as more of these elements are added to the soil with fertilizers than are removed with the harvest. The potassium balance is negative, so it is necessary to increase the application of potash fertilizers.
