Biochar promotes the dissolution of inorganic inactive phosphorus by strengthening phoD-harboring bacterial communities during rice stover and sheep manure co-composting
Inorganic phosphorus (P) predominantly exists as insoluble fractions in natural soil environments, particularly in calcareous soils where calcium-bound stable P and occluded P represent major non-labile P pools. This study investigated the regulatory effect of biochar amendment on the transformation and fractionation...
