Response of Soil Respiration to Grazing in an Alpine Meadow at Three Elevations in Tibet

Relationships between belowground root biomass (BGB, kg m−2) and total N (TN, g kg−1), ammonium N (-N, mg kg−1), soil available N (SAN, mg kg−1), the ratio of SOC and TN (SOC/TN ratio), and the ratio of -N and nitrate N (-N/-N ratio), respectively. SOC and TN data were obtained from Fu et al. [22].
