摘要：
Decreases in soil microbial metabolic quotient (qCO2) have been frequently observed under biochar amendment; however, the potential driving factors are not fully understood. This study aimed to investigate whether changes in qCO2 under biochar amendment could be closely linked with the alterations in soil carbon and nitrogen quality, microbial community composition and enzyme activity in both bulk and rhizosphere soils.
