Correction to: Soil microbial biomass phosphorus can serve as an index to reflect soil phosphorus fertility

The effect and relative contributions of C P inputs on soil microbial biomass (MBP) accumulation were studied in three long-term fertility experiments with various climate characteristics at Qiyang, Yangling, Wulumuqi. maximum MBP all sites was 47.8 mg kg-1. accumulated per unit (mg kg-1 soil) correlated a 4.91 increase Olsen P. For each surplus (kg ha-1), manure stubble increased by 330, 3.7, 13 units (μg soil), respectively. positively crop yield uptake, making the useful index. critical levels pool 140 kg ha-1, 57–62 33–35 ha-1 acidic red soil, loessial grey desert This is first report to establish quantitative index based pool. Our findings demonstrate that input good driver accumulation. Integration as an into agricultural management help manage mineral fertilizers part sustainable practices.
