As a result of the carried out researches it is established that during the existence of the ordinary chernozem soil agrocenosis in the horizon profile 0-20 cm formed a specific complex mikroartropod, the majority of groups of mites and springtails, by the nature of the power being saprofagami will no doubt play an important role in the cycle of substances affecting the productivity of the agrocenosis. Meadow agrocenosis, as 25-year-old section, characterized by progressive processes of natural steppe territories, the reason and the formation of specific complex studied mikroartropod. Soil excavations revealed a specificity of formation of soil fauna during the 25 years of existence of the agrocenosis of perennial grasses. Due to strong seals, turfing and draining soils agrocenosis no longer draws for egg laying adults shchelkunov, unfolding, pylceedov. Studies have shown that long term cultivation of perennial grasses in rainfed conditions chernozem zone contributes to the accumulation of soil-borne species mnogyadnyh fitofags. In addition, reduced the number of such zoofagov as ground beetles and stafilids, experiencing not only adverse effects of thickening of crops and soil compaction, but also a reduction in the density of populations victims.
