The formation of the agrogenic typical chernozem profile in the Ukrainian forest-steppe after plowing virgin steppe and fallow soils

Abstract

The data on the changes in the physicochemical, biological, and agrochemical properties of a loamy-clayey typical chernozem after plowing a 40-year-old Fallow (for six cycles of a cereal-beet rotation) and a sandy-loamy typical chernozem (for eighteen cycles of a five-course rotation) under different intensities of their use are presented. The major role of the mineral and organic fertilizers and the methods of their application have been revealed in the formation of the humus profile, the acid-base characteristics, and the agrophysical and agrochemical properties.
