NOVELTY - Organic composite fertilizer comprises 20-25 pts. wt. oat straw, 8-10 pts. wt. reed root river mud, 10-12 pts. wt. furfural residue, 5-8 pts. wt. chicken manure granules, 0.4-0.6 pts. wt. ammonium phosphate, 0.1-0.15 pts. wt. magnesium sulfate, 1.5-2.0 pts. wt. potassium dihydrogen phosphate, 1-2 pts. wt. urea, 0.02-0.04 pts. wt. calcium superphosphate, and 100-120 pts. wt. distilled water.    USE - The fertilizer is useful for growing broad beans (claimed).    ADVANTAGE - The fertilizer: can be easily absorbed by plant roots; can be penetrated into soil of broad bean roots; is fully absorbed by the plants; and solves the problem of existing inorganic fertilizers, which destroys soil structure.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the organic composite fertilizer, comprising (i) harvesting oat straws, casting in rows, drying in sun till the moisture content is less than 10%, pouring in pulverizer and crushing to obtain oat straw of a length not longer than 5cm, sealing and storing, (ii) selecting reed root areas growing for more than 2 years, collecting the reed root river mud mixture, collecting 10-30 cm of river bottom including mud and reed root, drying, grinding to obtain granules having diameter of 1-2 cm of reed root river mud particles, sealing and storing, (iii) extracting sulfuric acid from corncobs, collecting furfural residue, adjusting pH, drying by placing in oven at 100 degrees C for 1-2 hours, sealing and storing, (iv) drying the chicken manure by placing in oven at 100 degrees C for 1 hour, adding activated carbon during the drying process to deodorize and crushing the particles, (v) taking oat straw from step (i), furfural slag from step (iii) and chicken manure particles from step (iv) and blending to obtain an organic compost, (vi) adding distilled water to organic compost obtained in the step (v), pouring the resulting organic compost in the fermentation tank, adding composting bacteria for operations, continuing fermentation for 10-12 days, to obtain solid residue and liquid organic composite fertilizer, (vii) keeping the liquid organic composite fertilizer under sealed condition, placing into high-pressure steam sterilization pot and sterilizing, (viii) adding ammonium phosphate, magnesium sulfate, potassium dihydrogen phosphate, urea and calcium superphosphate to the sterilized liquid organic composite fertilizer to obtain a mixed solution composite fertilizer, and (ix) taking reed root river mud granules obtained in step (ii) for further grinding to obtain powder of 0.1-0.2mm size, spraying the solid powder on mixed solution composite fertilizer, and mixing uniformly for 2-3 hours to obtain the final suspension product.
