Effects of Simulated Nitrogen Deposition on Soil Nutrients, Microbial Biomass and Enzyme Activities in Abies georgei var. smithii Forest
Nitrogen deposition has emerged as a significant threat to alpine forest ecosystems on the Qinghai–Xizang Plateau. However, the specific responses of subalpine fir soil to increasing nitrogen input remain relatively unknown. To investigate the effects of simulated nitrogen (N) deposition on the soil ecosystem of Abies...
