SOIL STRUCTURE AND ORGANIC SUBSTANCE OF THE CHARACTERISTIC FORE-URAL CHERNOZEM OF THE WOODS AND LONG-TERM ARABLE LANDS ^{[№ 2 ' 2005]}
The authors carried out a comparative analysis of the characteristic Fore-Ural chernozem of the woods and long-term arable lands. They found out that in conjunction with low soil density, high indexes of the soil structure watertightness and soil permeability are stipulated by the humus substances of the hydrophobic fraction dominating in composition. This index of hydrophobic and hydrophilic fraction correlation can be used in the soil and land monitoring system.

ANTROPOGENIC EVOLUTION OF SOIL OF BOROVSKY IRRIGATIVE SYSTEM ^{[№ 1 ' 2005]}
Peeled solonetz and meadow-chernozem, deeply salt soil, occupied different positions in mesorelief , are revealed on the territory excluded irrgation of Borovsky irrigative system. Peeled solonetz is situated in comparative decline and, in comparison with meadow-chernozem soil, is greatly salted on the surface, also it is characterized with high content of natrium ion in soil absorbent complex, residuality and low permeability.
