QUALITY CONTROL OF SOIL QUALITY VIRGIN AND ARABLE TERRITORY OF ORENBURG PREDURALIE ^{[№ 10 ' 2015]}
Earth Orenburg region characterized by high natural fertility. The share of the most fertile soil — chernozem leached, typical and ordinary accounts for more than 40 % of the regional soil, and with southern black earth, this share rises to 56.6 % of the total area of the region. Among agricultural land, this percentage increases to 75 %. Currently, the area of arable land has achieved great performance and is 56.6 % of the agricultural land and 49.6 % — of the total area of the region. Intensity of use of land resources of the Orenburg region accompanied by a change of soil properties and increasing negative processes, which reduces soil fertility and, as a result, the yield of crops. According to the natural and agricultural zoning of land assigned to subboreal soil-climatic zones of the central steppe and steppe soil-biological field or forest-steppe, steppe and dry steppe natural and agricultural zones. Large areas of the Orenburg region lie in the area of black earth soils. Only in the south recorded dark chestnut soils in the north marked a small area of gray forest soils. Research quality of soil located under the well-preserved natural vegetation and in areas of intensive agricultural use was carried out on the territory of Orenburg Ural region and involves certain agro, agro-chemical and agro-ecological properties of soils. Experimentally established decrease in quality parameters of fertility soils under study as a result of intensive agricultural use. Analysis of laws between agrophysical, agrochemical and agro-ecological properties of soils allow the use of the materials obtained in the performance of eco-economic monitoring of agricultural landscapes of Orenburg Ural region, as well as significantly improve the accuracy of forecasting models to determine the direction and rate of change of the fundamental properties of soils as a structural and humus condition of chernozems. In order to improve the quality of arable soil areas, it is recommended to carry out the development of soil-mapping groups of Orenburg Preduralja agrophysical, agrochemical and agro-environmental indicators.

EFFECT OF LONG-TERM AGRICULTURAL USE ON HUMUS SOIL CONDITIONS OF THE SOUTHERN URALS ^{[№ 10 ' 2013]}
The results of the analysis of the state of humus chernozems and dark chestnut soils of the Urals, as well as their dynamics is evaluated in a number of virgin land — arable land. Among the identified geographical zoning changes such indicators of humus, as its contents and reserves, the type of humus content of mobile fulvic and humic acids associated with calcium.

REMOVING THE AMOUNT OF RARE EARTH ELEMENTS BY INTEGRATED WASTE PROCESSING INDUSTRY ALUMINA URAL ALUMINUM PLANT ^{[№ 12 ' 2011]}
Every year more than one million tons of bauxite processing wastes at the alumina refineries come on sludge. These flood the tailings pond are the sources of pollution of surface and underground bases reservoirs, as well as a large dusty atmosphere. In practice, existing facilities are currently no alkaline waste recycled. At the same time wastes are promising sources of various compounds. Therefore the problem of integrated waste management facilities to the production of alumina products of chemical and metallurgical purposes is an important reserve for increasing production efficiency, both in the direction of rational use of raw materials and the preservation of our living environment.

DISPERSIVE ANALYSIS MONTMORILLONITE-BEARING OF CLAY OF ORENBURZHYE ^{[№ 12 ' 2011]}
The dispersive analysis montmorillonite-bearing clay of Orenburzhye, based on screen fractionation, sedimentation and optical microscopy is carried out. It is established that division of investigated clay on two fractions is expedient. From low-dispersed fractions by optimization of modes of synthesis probably reception of microporous ceramics of high density and durability.
