PROCESS OF PRODUCING BIO-ORGANO-PHOSPHATE (BOP) FERTILIZER THROUGH CONTINUOUS SOLUBILIZATION OF ROCK PHOSPHATE BY COMPOSTING BIOPROCESS AND BIOAUGMENTATION WITH PHOSPHORUS SOLUBILIZING MICROORGANISMS

摘要

A method and processes to solubilize and transform phosphorus contents of rock phosphate (RP) into bio-organo-phosphate (BOP) fertilizer have been developed and integrated. The methods include collecting and sorting of organic wastes; blending with RP; subjecting the blend to biocomposting; collection, isolation, selection and growth optimization of consortia of efficient phosphorus solubilizing microorganisms (PSM) and novel plant growth regulating microorganisms (PGRM); where in PSM produce organic acids and other organic compounds using compost substate at mesophilic stage, whereas the organic acids released during composting also act in synergism of PSM, thus forming a carbon rich acidic culture resulting in the solubilization of rock phosphate.

1. A method of producing bio-organo-phosphate (BOP) fertilizer through continuous solubilization of rock phosphate by a composting bioprocess and bioaugmentation with consortia of efficient phosphorus solubilizing microorganisms (PSM) and novel plant growth regulating microorganisms (PGRM), said method comprising:
isolating and selecting microorganisms (i.e. PSM and PGRM); producing inocula containing consortia of PSM and PGRM; composting; blending organic matter and rock phosphate; augmenting rock phosphorus enriched compost (RP-EC) with a consortia of PSM and PGRM; and producing BOP fertilizer.
