ROLE OF LANDSCAPE ASYMMETRY IN SOIL FORMATION AND TOP-SOIL OF PREDURALYE ^{[№ 4 ' 2005]}
Characteristic geomorphological feature of Orenburg Preduralye is a landscape asymmetry. Heterogeneity of soil formation processes is connected to it proceeding on slopes of different directions. Distinctions of ecological conditions of soil formation find the reflection in dissimilar parameters of a microclimate, in composition and structure of natural phytocenosis, in mechanical structure of soil forming rocks, in duration of the period of biological activity of soils, that is shown in morphological, chemica,l biological and other major genetic properties of soils of slopes. Recommendations are given for agricultural use of territory, the ecological status of object of research is determined.

CONCEPTUAL, APPLIED AND PRACTICAL ASPECTS OF SOILS AND AGROLANDSCAPES PLOUGHING FITNESS THEORY. ^{[№ 4 ' 2001]}
The article provides the analysis of the ploughing effect on homeostasis of soil biogeocoenosis. The necessity of long-term ploughing field productivity and soil ecological functions in biosphere is quite obvious, hence the authors prove the necessity of agrulandscape differentiation according to the degree of plouqhinq fitness as the major factor of agricultural nature use optimization. The criteria of such division are shown. Regional soil and lands cape division into the plouqhinq fitness categories was carried out according to thesoil-economic conditions the Orenburg region territory.
