NOVELTY - Producing bio-organo-phosphate (BOP) fertilizer through continuous solubilization of rock phosphate by composting bioprocess and bioaugmentation with consortia of phosphorus solubilizing microorganisms (PSM) and novel plant growth regulating microorganisms (PGRM), involves 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 consortia of PSM and PGRM; and producing BOP fertilizer.    USE - For producing bio-organo-phosphate (BOP) fertilizer (claimed).    ADVANTAGE - The phosphate solubilizing microorganisms produce organic acids and other organic compounds within compost substrate, which thereafter may be bioaugmented with novel plant growth regulating microorganisms to facilitate phosphorus (P) bioavailability to plants for better growth. The method allows one to formulate an excellent P-enriched product for organic agriculture with no synthetic process involved. The method gives supply of organic phosphate which can not only supply soluble organic phosphates but also release amount of P through microbial mineralization of organically bound P. The method introduces/promotes integrated nutrient management through regular supply of nutrients from decomposing organic matter enriched with rock phosphate and augmented with PSM and PGRM; and improves soil health and plant roots architecture in addition to nutrient supplements versus classical chemical fertilizer supplying nutrients only. The method uses more efficiently and effectively all grades of rock phosphate with significant reduction in energy consumption, water use, and largely eliminates release of environmental pollutants. The continuous use of the organic phosphate product develops soil environment conducive for mobilizing other nutrients for better uptake by plants leading to enhanced soil productivity. The organic phosphate has better use efficacy due to less probability of fixation, precipitation or insolubilization of added P; and its better utilization by plants due to improved root architecture than that observed in case of current commercial soluble chemical/inorganic fertilizers; and helps to reduce ever increasing per hectare use of phosphatic fertilizers.
