BIOLOGICAL METHODS OF RESTORATION OF FERTILITY OF DEGRADIATED SOILS OF THE SOUTHERN URAL FOREST-STEPPE OF THE REPUBLIC OF BASHKORTOSTANIntensive 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.Key words: soil, humus, organic farming, biological farming, nitrogen, biofertilizers, soil degradation.
