Iy. Savin et Iv. Kuznetsova, About the similarity of background components of the soil cover in the southern forest-steppe zone of the central Russian upland with respect to their physical properties, EURAS SOIL, 33(3), 2000, pp. 269-273
The similarity and differences between representative profiles of typical a
nd leached chernozems with respect to their physical properties (the conten
t of physical clay (<0.01 mm), clay, and sand particles; soil compactness;
and the content of water-stable aggregates) and the content and reserves of
humus are analyzed. The comparison between these subtypes of chernozems is
performed in two variants: (a) with regard to their position in a particul
ar soil combination and (b) irrespectively of the place of these soils in t
he soil cover. The properties of individual soil horizons are also compared
. The major reasons of spatial variability in soil physical properties are
revealed.
