The study of the biological properties of soil deposits of different ages Myasnikovske Rostov region. Research site is a series of deposits left without treatment in different years (in the 1930s., in 1986 and 1996). As diagnostic indicators were selected humus, soil enzyme activity, floristic composition. As a result, research on fallow plots were registered just 109 species of vascular plants belonging to 81 genus, 24 families. However, fallow plots of different ages varied role of individual families. Deriving soil accumulation accompanied by an increase in invertase activity and polyphenol oxidase and peroxidase activity decreases. In soils deposits 1930s humus content is 1.5 times more compared to other deposits, as compared with more arable land 3 times.
