Changes in some properties and bioproductivity of soddy-podzolic soil depending on slope exposure

摘要

The differentiation of some chemical properties and bioproductivity parameters in the eroded cultivated soddy-podzolic soil, depending on the slope exposure, was investigated. Peculiar features of humus accumulation and humification, depending on the position on the slope, microrelief, and microslope gradient were revealed for the southern slope, characterized by the most mottled soil cover. A moderate positive correlation was found between the bioproductivity of individual edaphic varieties of eroded soddy-podzolic soil and the humus content in the 0- to 40-cm layer.
