Data from "Litter addition outweighed litter removal in affecting soil nitrogen-hydrolyzing enzyme activities in subalpine forest ecosystems"

We conducted a two-year detritus inputs and removal treatment (DIRT) experiment in subalpine coniferous (Pinus yunnanensis) and broad-leaved (Quercus pannosa) forests in Southwest China. And we evaluated the impacts of litter addition (i.e., double litter, no roots with double litter) and removal (i.e., no litter, no roots, and no litter and no roots) on NAG and LAP activities and their key drivers in both topsoil (0-10 cm) and subsoil (10-30 cm) by comparing with the control.
