Abstrakt: The scientifically based fertilizer system used in the 11-field grain-grass-row crop rotation promotes an increase in the lethargic respiration rate in chernozem by 20.6-22.1% and catalase activity by 21.9-27.3% with very little activity of ferric reductase. On high rice checks of meadow chernozem soils, compared to low meadow-marsh soils, the intensity of respiration increases by 18.5-22.8%, catalase activity by 15.0-28.6%, and the activity of ferric reductase decreases 21.4-41.3%. Irrespective of the agricultural use of soils, biochemical processes are more active in the 0-20 cm layer. Permanent cultivation of rice for 80 years on meadow-chernozem soil leads to a decrease in the intensity of respiration and the activity of oxidation-reduction enzymes. The ratio of the activity of ferric reductase and catalase can serve as an indicator of the oxidation-reduction state of soils and, along with iron compounds, characterize the degree of their hydromorphicity.
