Average concentrations of a, b microbial necromass C (MNC) and c, d biomass C (MBC) at control and N addition plots. e Average concentrations of soil organic C (SOC) at control and N addition plots. f Average ratios of microbial necromass C to microbial biomass C at control and N addition plots. The above panels show the values presented on the basis of soil dry mass (mg/g soil), and the below panels show the values presented as percentages of soil organic C (% SOC). Error bars represent the standard errors. The MBC values were analyzed by the chloroform fumigation extraction method. The data in panel f were collected only from cropland sites, at which the MBC concentrations were determined
