Relationship between physical-chemical and biological indicators of meadow-brown soils

The article presents the results of research on the relationship between some physicochemical and biological indicators of meadow-brown soils of semi-humid subtropics of the Lenkoran. The characteristic relationships between the humus content and the absorption capacity, as well as between the number of microorganisms and the reactions (pH) of the soil environment, have been studied. The analysis of the dependence of the investigated quantitative indicators is presented. As a result, it is concluded that there is a relationship between the soil absorption capacity and the humus content in meadow soils. The pH of the soil medium ranges from neutral to slightly alkaline.
