Characteristics of microbiological activity of soils during their excessive moistening

The results of the study of the microbiological activity of sod-podzolic soils of varying degrees of hydromorphicity and meadow-chernozem soils under rice are presented. When they are excessively moistened, there is an increase in the number of oily, acid-reducing, sulfate-reducing bacteria, anaerobic bacteria of the genus Clostridium, a decrease in catalase activity, an increase in the activity of nitrate reductase, as well as an increase in the ratio of mobile forms of Fe:Mn. The number of microorganisms was influenced by the introduction of siderates and NPK. It is proved that the regulation of appropriate farming systems allows optimizing soil fertility levels. The introduction of KNO3, J, Mo, Mn into the soil also had a positive effect on soil fertility.
