The identification and quantification of labile and recalcitrant soil organic matter (SOM) forms can be used to evaluate the impacts of management on soil quality (SQ). This study characterized the SOM through chemical and granulometric fractionation in areas located in the Savannah biome. Preserved, cultivated and environmental recovering areas were evaluated. For all fractions of SOM, except for the particulate organic carbon (POC), the preserved areas showed higher levels. The SOM had a positive correlation with the cation exchange capacity and negative with bulk density of soil (p ≤ 0.01). The results showed that SOM improved the physical and chemical SQ, and crops reduced the levels of carbon (C) in SOM fractions, negatively affecting the SQ. |
