In course of the research there was studied the content of hydrolysable and not hydrolysable substances in arable layers of the previously undisturbed lands and cultivated peat soils various genesis. The research was realized in the conditions of the Republic of Belarus. As a result of the research it was revealed that the content of hydrolysable substances in arable layers of the cultivated peat soils substantially lower, and not hydrolysable - higher, than in analogues layers from the drained virgin soils. The lowest content of hydrolysable substances was observed at cultivation raw crops. The maximal quantity of hydrolysable substances was containing in arable layers of soil profiles, the least - in subsurface layers. Distinctions in the content of hydrolysable substances in upper and lower layers of soil profiles make up from 13 till 38% to total soil organic matter. Biochemical stability of organic matter in subsurface layers was essentially higher, than in the arable ones.
