Microbial nutrient limitations in soil during afforestation in the Mu Us Desert, China: insights from extracellular enzyme stoichiometry
Afforestation is a key ecological restoration measure for combating desertification in arid and semi-arid regions. But the changes and drivers of nutrient limitations faced by soil microbes during long-term afforestation are unclear. This study investigated soil ecosystems of different-aged stands (planted 10, 30, 50...
