Organic Matter in the Soils of the City of Volsk (Saratov Region)
The concentrations of organic matter in the soils of Volsk (Saratov region) are determined. It was found that the concentration of organic matter varies from 0.57 to 2.34% with an average value of 1.88%. The distribution of organic matter in the background area varies from 2.03 to 2.33% with an average value of 2.25%. Thus, it can be noted that in the city of Volsk a decrease in the content of organic matter is observed in comparison with the background values. Taking into account the revealed tendency to decrease the fertility of the soil cover in the city of Volsk and information on possible reasons for the activation of this process, a number of recommendations have been developed that promote the accumulation of organic matter.
