Plastic films mulching, a management strategy designed to boost agricultural productivity, significantly impacts soil fertility and the turnover of soil organic carbon (SOC). Aggregates in the soil play a crucial role in this SOC cycling. Yet, the effect of mulching on the changes in organic carbon components and the mineralization at the aggregate scale is still not well understood. The authors conducted a three-year field experiment to examine the effects of various mulching types (CK: non-mulching, BPM: black polyethylene mulching, CPM: colorless polyethylene mulching, BDM: black degradable mulching, CDM: colorless degradable mulching) on the transformation and mineralization of organic carbon within soil aggregates.
