NOVELTY - A storage stable activity enhancing biofertilizer formulation/composition (C1) comprises: synergistic combination of earthworm cocoons and microorganism selected from Azotobacter and/or other nitrogen-fixing bacteria in the presence of a bio compatible carrier adapted to synergistically enhance the soil fertility and yield.    USE - As a storage stable activity enhancing biofertilizer formulation/composition, useful for improving fertility of soil (claimed).    ADVANTAGE - The composition synergistically enhances the soil fertility and yield; and synergistically enhances biofertilizer activity by way of favorable proportionate change in microorganism level vis-a-vis cocoon during storage. The package is adapted for synergistically enhanced biofertilizer activity by way of favorable proportionate change in microorganism level vis-a-vis cocoon during storage.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1) a storage stable activity enhancing biofertilizer formulation/composition (C2) comprising: encapsulated/coated earthworm cocoons including non-steamed rice grain paste based encapsulation/coating material for extended storage stability and viability even after at least 12 weeks post application; 2) manufacturing (M1) a storage stable activity enhancing the biofertilizer formulation/composition involving providing selectively a synergistic combination of earthworm cocoons and microorganism selectee from Azotobacter and/or other nitrogen-fixing bacteria in the presence of a biocompatible carrier adapted to synergistically enhance the soil fertility and yield; 3) manufacturing (M2) a storage stable activity enhancing the biofertilizer formulation/composition involving providing encapsulated/coated earthworm cocoons involving non-steamed rice grain paste based encapsulation/coating material adapted for extended storage stability and viability even after at least 12 week, post application; 4) a biofertilizer package comprising earthworm cocoons and microorganism selected from Azotobacterand/or other nitrogen-fixing bacteria in the presence of a bio compatible carrier adapted to synergistically enhance the soil fertility and yield by way of enhancer penetrating, ability and nitrogen fixation for soil fertilization; 5) improving (M3) the fertility of the soil involving providing a storage stable earthworm activating biofertilizer formulation/composition comprising a synergistic combination of earthworm cocoons and microorganism selected from Azotobacter and/or other nitrogen-fixing bacteria in the presence of a bio compatible carrier; applying the biofertilizer formulation/composition on the soil to synergistically enhancer the activity of the microorganism by way of enhanced penetrating ability and nitrogen fixation for soil fertilization; and 6) improving the fertility of the soil involving providing a storage stable activity enhancing biofertilizer formulation/composition containing encapsulated/coated earthworm cocoons involving non-steamed rice grain past based encapsulation/coating material; applying the biofertilizer formulation/composition on the soil to enhance the soil fertilizer and yield by retaining the viability of the cocoons even after at least 12 weeks post application.
