Purpose Variation in soil microbial metabolism remains highly uncertain in predicting soil carbon (C) sequestration, and is particularly and poorly understood in agroecosystem with high soil phosphorus (P) variability. Materials and methods This study quantified metabolic limitation of microbes and...
