摘要：
Decomposition of forest litter plays a major role in nitrogen (N) dynamics in soil. However, the effect of new litter on indigenous soil N and its contribution to soil N in natural forest remains unknown. An in situ soil column experiment was conducted and N-15 labelled litter was added to decompose for 14 months to examine the effect of litter retention on soil N dynamics in a typical subtropical forest. Litter removal in the soil column was used as a control. The results showed that litter removal caused a continuous decrease in concentration of soil soluble organic N (SON) in the first 5 mo...
