Perminova, "The structure of humic acids of zonal soils
according to C-13 NMR spectroscopy data," Pochvovedenie, no.
The results of empirical data large array processing about the maximum parameters zonal soil humus horizon (A + AB) and their respective conditions of heat and moisture provision in eight landscape zones of the East European Plain allowed get a general analytical expression of humus horizon extreme power with the energy costs on soil formation.
Provided that the variables ([N.sub.lim]) for region zonal soils are justified (for example, on the East European Plain they make at least 9 of the main soil types), the equation (4) may be graphically represented as a series of curves.
The zonal soils
, which dominate the forest hill level, are brown and brown luvic soils (podzolic, locally pseudogleyised), whereas the silvosteppe level found in the valleys is dominated by chernozems, cambic and clay-illuvial.
For definition of hydro-physical properties of zonal soils
of the European Russia, we chose testing areas in various soil and landscape zones of the European territory of Russia [6-9].

The process is best expressed in the well drained zonal soils
of the high plain, especially in Argiudolls.
The zonal soils
in both grass- and shrub-dominated areas were grey desert soil derived from colluvial--eluvial material according to Chinese Soil Taxonomy, which is equivalent to the Camborthid in terms of USDA Soil Taxonomy classification (Shapotou Desert Research Station 1980; Qiu et al.
