Sablina O.A. AGROGENE TRANSFORMATION OF HUMUS STATUS IN SOUTHERN CHERNOZEM OF THE STEPPE TRANSURAL REGIONThe ecological status of southern chernozems in different agricultural areas of the Orenburg steppe Transural region is investigated. It was established that the greatest loss of organic matter observed in fallow and arable soils. In grasslands soils reduction of humus content and reserves is insignificantly. The main reason of dehumification of agricultural soils can be considered reduce of underground phytomass reserves. Reliable indicator of the degree of agrogenic transformation humus condition in chernozem of Orenburg Transural region is the intensity of carbon dioxide production. Key words: agrocenosis, biological activity, humus, chernozem, virgin land, arable land, hayfield, grazing areas, fallow land.
