Quantifying the Combined Effect of Abiotic Factors on the Decomposition of Organic Matter in Semiarid Grassland Soils

Grassland ecosystems play a critical role in the global carbon cycle, and their cumulative carbon dioxide (CO2) emissions can be affected by animal grazing where litter (i.e., dead plant material) is trampled into the soil. However, the subsequent effects of trampling on litter decomposition are not
