BIOSYSTEM OF CROP FARMING IN THE DRY-STEPPE ZONE OF SOUTH URALS: THEORY AND PRACTICE
The results of studies conducted by Orenburg researchers on formation of the arsenal of specific, environmentally sound agricultural activities of different purposes, foreseeing the rational use of bioclimatic potentials, are submitted. The data obtained by testing the No-till technology and peculiarities of its use in the dry-steppe zone in years with different climatic conditions are suggested. The influence of biological agro-measures on the habitat quality of soil organisms, which in their turn form agrophysical and agrochemical properties of soil, has been assessed. The role of sorghum windbreak rows (coulisses) in the microclimate formation, wind speed in the surface layer and moisture evaporation, the increase in the possibility of snow accumulation for winter crops wintering and creation of optimal conditions for ensuring the life activity of soil invertebrates for the purpose of soil structuring is shown.
