Abstract

Investigated direction and intensity of microbiological processes in gray forest soils of varying duration as compared to extensive and intensive ahrozemamy. It has been established that the number of microorganisms of certain ecological trophic and functional groups in the ground of the foreground changes with the time of its stay in the state of reflux. The largest number of microorganisms is characterized by microbial grouping of long-term overeating: it contains more microorganisms in the nitrogen cycle and less microorganisms in the carbon cycle compared with fewer periods of shorter duration. The soil of a long-term overgrowth is characterized by the highest total biological activity, which exceeds the activity of the soil of the perehlava from 2000 by 72.9%, and from 2007 - by 48.8%.

With the increase in the duration of the flood, the intensity of the organic matter development of the soil is reduced to

3.26 and 2.59 times for the revisions from 2000 and 1987, respectively; the processes of humus destruction considerably slow down: the activity of mineralization of humus in the soil of a perennial flood is lower than the corresponding indexes of revisions from 2000 and 2007 by 50,0 and 60,0%; the phytotoxicity of the soil decreases by 9.47%.
