Soil organic matter (SOM) is a heterogeneous material consisting of different functional groups depending on soil texture and moisture regime. The lability of SOM (rapidity of turnover rate) is also an important indicator in soil quality evaluation. In this study, SOM lability (p-WEOC) was assessed...
