Ґрунти ФГ Коньшина С.В. Куп'янського району Харківської області та шляхи підвищення їх родючості

Abstract

The work is devoted to the study of the features of the soil cover of one of the farms of the Kharkiv region and the development of ways of rational use and increase of their fertility. It has been established that the soil cover of the farm includes 36 types and varieties of soils and rock outcrops. The soil cover of the farm is dominated by podzolic and washed chernozems, their varieties. Calculations of the humus balance in the soils of the farm show that in all crop rotations there is a deficit of humus, which ranges from -0.04 -0.21 t/ha in soil-protective crop rotations to - 0.70-0.79 t/ha in field crop rotations. To ensure a deficit-free balance of humus in the field crop rotation, it is necessary to increase the dose of organic fertilizers by 11-13 t/ha, that is, the total rate of organic fertilizers should be 13-15 t/ha of the crop rotation area.
