Response of soil enzyme activities to litter input changes in two secondary Castanopsis carlessii forests in subtropical China

Aims Enzymes play an important role in the decomposition of soil organic matter. Changes in net primary productivity in response to climate change are likely to affect litter inputs to forest soil. However, the effects of altered litter input on soil enzyme activities remain poorly understood in subtropical forests. Thus, this study is designed to find out if litter manipulation has an effect on enzymes in different subtropical Castanopsis carlessii forest.
