Changes in labile phosphorus forms during maturation of vermicompost enriched with phosphorus-solubilizing and diazotrophic bacteria

► We combined diazotrophic and P-solubilizing bacteria with rock phosphate during vermicompost process. ► Over the time of vermicompost maturation, changes in P and N contents were assessed. ► Availability of P-labile forms was connected with increased phosphatase activity. ► We had shown that with proper combination of bacteria that is possible to enhance vermicompost value.
