Biochar addition promotes dissolution of inorganic inactive phosphorus by strengthening the function of phoD-harboring bacterial community during corn stover and cattle manure composting

This study investigated the effects of adding biochar on inorganic P fractions during composting, and analyzed the role of phoD-harboring bacterial community in solubilising inorganic non-labile-P using techniques such as high-throughput sequencing, isolation cultures and network analysis.
