BIOLOGICAL METHODS OF RESTORATION OF FERTILITY OF DEGRADIATED SOILS OF THE SOUTHERN URAL FOREST-STEPPE OF THE REPUBLIC OF BASHKORTOSTAN ^{[№ 11 ' 2017]}
Intensive farming has led to the depletion of land resources, so the reproduction of soil fertility and the use of agroecological methods of farming systems is an important task of the present. The world community increasingly pays attention to those methods of agriculture that ensure the maximum crop yield with minimal impact on the environment. Biologization of agriculture is one of the important links in the production of ecological products and the reproduction of soil fertility. The paper presents the results of a study of the effect of various elements or components of biological methods for restoring soil fertility (wheat and pea straw, manure, siderates, poultry manure, sapropel) in comparison with mineral (NPK) 60 and without mineral for crop yields and agrochemical, agrophysical, physico-chemical and biochemical properties of soils. It has been established that biological methods of farming increase the humus content by an average of 0.1–0.15 %, in connection with which the fertility of the soil increases, which leads to an increase in yield by an average of 15–20 %. One of the most effective method of biologization of agriculture is the application of manure 15 tons per hectare and bird droppings at doses of 40 to 60 tons per hectare, which is why the yield of agricultural crops is increased by more than 25 percent, and the humus content is increased by 0.1–0.5 %. It is revealed that the application of biological farming systems increases the formation of humus and nitrogen reserves, exerts a complex effect on all factors of soil fertility, which ultimately leads to an increase in crop yields.

INFLUENCE OF A RELIEF ON STOCKS OF SNOW COVER AND MOISTURE ON FOREST SOILS ^{[№ 6 ' 2017]}
The woods play a large role in water cycle, enrich the atmosphere with oxygen and support balance in the nature, and also the woods carry out the water preserving, protective, antierosion, sanitary and hygienic, improving, recreational functions. Studying of stocks of snow, their definition is to important components of life cycle of the wood. Researches of stocks of snow cover were conducted on the timberland of GU of the Ufa forest area which includes nine local forest areas: Demsky, Pokrovsk, Ufa, Chishminsky, Yumatovsky, New and Troitsk, Blagoveshchensk, Oryol, Blagovarsky statistical, mathematical calculation, and also analysis of references. During the researches snow-measuring shooting has been carried out and the obtained data are processed in geographic information systems. Observations of indicators of height of snow cover on the timberland are presented for 2015–2016 from October to April. Determined height, density and structure of snow cover. Proceeding from the obtained data, have defined the water-supply which is contained in snow cover, for each studied month. Then the summary table by results of field and cameral works has been made. Further, using GIS-technologies, digitization of the topographic map of the timberland and the nearby territory is made, then results of researches are caused on her.

RETROSPECTIVE MONITORING OF ZINC, ARSENIC, LEAD AND CADMIUM IN SOILS OF FOREST AND MEADOW ECOSYSTEMS SOUTH URAL ^{[№ 9 ' 2016]}
Due to living matter in the soil are concentrated and redistributed post-drank from the rock, the atmosphere and living organisms, chemical elements throughout the periodical systems, which are destroyed in their turn to form new compounds, they are under the constant influence of kinetic and thermodynamic forces animate and inanimate nature. The article presents the materials on the content of zinc, arsenic, lead and cadmium in the soils of the Southern Urals. The behavior of these elements in the retrospective aspect. SimilarResearch in the Southern Urals has not yet been carried out. The first results shows the presence of significant changes in the content of elements in the retrospective aspect. New concepts like biogeochemical activity and biogeochemical potential element in the soil. The thermodynamic performance oxides Education: Enthalpy, Entropy, Gibbs Energy. It was found that the greatest contribution to the soil-forming process in the conditions of Southern Urals are making zinc, arsenic, to a lesser extent lead and cadmium, to a small extent. From the point of view of ecology are major pollutants zinc and arsenic. Hundred- arable soil on the content of zinc, arsenic, lead and cadmium degraded almost to the level of a light-gray forest soils, evidenced by stocks of these items on a profile soil and thermodynamic constants.

THE BASIC AND PRESOWING WORKING OF SOIL FOR THE SUGAR BEET IN THE REPUBLIC OF BASHKORTOSTAN ^{[№ 10 ' 2010]}
The authors presented the results of studies on the study of effectiveness in the basic and presowing processing of soil for the sugar beet in the Republic of Bashkortostan. The authors gave three year experimental data (2006-2008 yr.) on the influence of different methods to the basic and presowing processings of soil by the domestic and imported soil-treating instruments. They noted that by the optimum method of the basic working of soil is the ploughing at the depth of 28-30 cm dump reverse plow, and by the best method of the presowing preparation of soil is its cultivation to the depth of 5-6 cm the cultivators "Kompaktor", KPPSH-6 and KPSH-9 as the ensured obtaining greatest productivity of root-crops.

MINING COMPLEX INFLUENCE OF OF ZAURALIE ON CHEMICAL STRUCTURE OF SOIL ^{[№ 1 ' 2007]}
The content and distribution of 63 chemical elements in rocks, soils of meadow and forest ecosystems of Zauralie mining region of Republic of Bashkortostan, confirmed with heterolevel antropogenic load, are studied in this article. The peculiarities and regularity of chemical elements distribution by soil profile depending on ways of their entrance, soil quality, presence of different geochemical barriers, natural anomalies and man-caused factors, are established here.
