Figure 3

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].
