Aromatic carbon from low-temperature biochar enhances bacterial phosphorus solubilization under saline-alkaline stress.
Co-applying biochar with phosphate-solubilizing bacteria (PSB) holds promise for ameliorating severely degraded ecosystem productivity due to low phosphorus (P) bioavailability in saline-alkaline soils. However, their interaction on how biochar reshapes microbial metabolism function remains poorly understood. Here, low...
