Sablina О.А. ECOLOGICAL FACTORS OF HUMIFICATION OF STEPPE SOIL OF ORENBURG TRANS-URAL AREA The article examines ecological factors of humification of virgin and arable soil of steppe Trans-Ural area within the limits of Orenburg region: climate, hydrothermic conditions, composition and sources of receipt of organic matter, soil biological activity; besides, water-physical and structural-aggregative properties of soil are examined. It is determined that agrogenic transformation of humification process erases zone-genetic features of agricultural landscapes soil. Key words: chernozem, liver-coloured soil, humification, hydrothermic conditions, soil biological activity, agrogenic factor.
