[Display omitted] •Soil P limitation constrains rather than promotes microbial C metabolism.•Removal of microbial P limitation by P addition increases CO2 release from soils by 19%–26%•Negative or positive relationship of microbial C and P limitations depend on soil C availability.•Alleviated microb...
