METHOD FOR DETERMINING THE RATIO transformable and inert soil organic carbon

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of soil biology and agroecology, and can be used as criteria for evaluating the soil fertility and potential emission of carbon dioxide with soils in climate change. The method comprises determining the total content of organic carbon in the soil sample (C content), the amount of potentially mineralised organic carbon (C pm) upon incubation of the same sample, resulting in the calculation of the transformed organic carbon content (C trans). The amount of inert organic carbon (C inert) is calculated by the formula C inert = C content - C trans.;EFFECT: acceleration and simplification of determining is achieved.;1 ex, 2 tbl
