Kudryk A. Dynamics of the soil formation of the eroded chernozems in the Ukrainian Zorest Steppe agrolandscapes

Thesis for a Candidat's degree of agricultural sciences by the speciality 06.01.03 - agricaltural soil science and agrophysics, Kharkov city, Institute for Soil Science and Agrochemistry Research named after A.N. Sokolovsky, Ukrainian Academy of Agricultural Science, 2001 Transformation appropriatnesses of morphometrical parameters, soil granulometrical composition, humic state, macro- and microelements content in the eroded typical chernozems during 30 years are determined. Peculiarities of an agricultural using influence to soil forming processes are shown. Connection of some regimes in humus-accumulative horizons of the eroded chernozemic soils with regimes in thier transitional ones is based. Technological methods to create and support an active humus balance and to reproduce a fertility of the eroded chernozems are carried out.
