摘要：

Microbial necromass nitrogen (MNN) is increasingly recognized as a major source of soil N, playing a crucial role in N sequestration and sustaining N balance. However, quantitative data on the contribution of MNN to total N and its relationship with soil multifunctionality (SMF) in karst plantation ecosystems remain lacking. In this study, MNN (measured via amino sugar analysis) and SMF (calculated using the mean value method) were determined across five plantations and unafforested land (control) in the Wuling Mountains of subtropical China. T...
