Change in aggregate structure of various soil types during the succession of abandoned lands
A comparative analysis of the changes in the aggregate structure in various types of soils (Sod-podzolic, Gray forest, and Chernozems) during their postagrogenic evolution was carried out. The study plots included: sod-podzolic soils -plowland, laylands abandoned 8, 13, 35 years ago and a secondary...

A comparative analysis of the changes in the aggregate structure in various types of soils (Sod-podzolic, Gray forest, and Chernozems) during their postagrogenic evolution was carried out. The study plots included: sod-podzolic soils -plowland, laylands abandoned 8, 13, 35 years ago and a secondary forest (~100 years); gray forest soils -plowland, laylands abandoned 6,15 and 30 years ago and a secondary forest of 60 years; сhernozems-plowland and layland abandoned 10, 15, 26 and 81 years ago. The geobotanical studies have shown that the withdrawal of soils from agricultural use causes changes in species composition, increase of biodiversity, and a gradual recovery of climax communities, which are attributed for specific natural climatic zones. Along with vegetation succession, we observed the increase in the total carbon content in the upper part of the former arable layer (0-10 cm) in all studied soils.
