Since Chernozems are among the most fertile soils in the world, the study of their degradation is of great interest. However, the microstructure and composition of the soil organic matter (SOM) in eroded Chernozems have not yet been sufficiently stud

Water-extractable organic matter is the most active and mobile form of soil carbon. The other active fraction and extremely biolabile is the carbon constituent of microorganisms. Both of these fractions play an essential role in agrocenoses and in th

One of the most justified and applied approaches to isolating pools of soil organic matter is fractionation in heavy liquids. The main problem with this approach is rather large losses in the separation of fractions at the stage of washing fractions

Double-shot pyrolysis with gas chromatography and mass detection (Double-shot GC MS) was conducted for a sample of typical chernozem and humic acids separated from it. The humic acids preparations were pyrolyzed at 500, 600 and 700°C. The data were

The purpose of the work is a comparative study of the molecular composition of thermolabile (volatilizes at 300°C) and thermostable (volatilizes at 500°C) fractions of organic matter from humus horizons of typical chernozems by double-shot pyrolysi

The paper presents research data on profiles of fatty acids in typical chernozems of various use. It is shown that organic matter degradation in typical chernozems is accompanied by depletion of fatty acids, while its accumulation results in an incre
