Khasanova R.F., Suyundukov Ya.T., Salmanova E.F. OPTIMIZATION OF SOIL HUMUS CONDITION STEPPE AGROECOSYSTEMSThe development of virgin land and arable use leads to a decrease of humus content in the soil, which is accompanied by the gradual destruction of valuable units and leads to the development of erosion processes, degradation of vast areas of steppe ecosystems. Restoration of disturbed steppe ecosystem is to recover as the natural vegetation and soil steppes. Perennial grasses form a large amount of organic matter and promote the formation of humus, activate vital activity of the soil microflora, provide cycling of matter, the formation of soil aggregates, and others. Thanks to a strong root system of perennial grasses also provide erosion protection of the humus layer of the flushing and blowing. The research is devoted to studying the role of perennial grasses to stabilize the soil with humus Zauralye the Republic of Bashkortostan. It was revealed that under perennial grasses, especially under the natural grass communities there is an intensive restoration of humus, which is closely correlated with the parameters of a biomass plant. Increased humus content decreasing the size of the units is accompanied by an increase in their water stability (r = 0,62). Introduction to the field crop rotations sown perennial grasses allows 2–3 years to increase the humus content in the soil at 0.3–0.5 %. Create Agrostep contributed to the restoration of natural vegetation and a positive balance of humus, the soil close to the virgin nature of the content and profile distribution. The most effective humification process occurs under steppes in the version with 4-kratnym disking on the background of fertilizers.Key words: humus, perennials, phytomass, agrostep.
