NOVELTY - Fermented biological organic fertilizer comprises raw materials comprising ammonium sulfate, urea, potassium chloride, monoammonium phosphate, humic acid, bentonite, sepiolite powder, shrimp shell powder, nanocarbon powder, boric acid, ammonium molybdate, and binding agent. The binding agent comprises raw materials comprising rice starch, yeast, maltose, water, sodium selenite, potassium hydroxide, borax, and tributyl phosphate.    USE - As fermented biological organic fertilizer.    ADVANTAGE - The fertilizer can be flexibly controlled, prepared using less number of labor and conveniently applied, uniformly distributes secondary elements and trace elements, is provided in form of controlled-release formulation which excerts ingredients for 30-150 days, has strong pertinency of fertilizer application, is stored and transported conveniently, and provides fertilizing effect ten times more than existing service radius, preferably 500 km.    DETAILED DESCRIPTION - Fermented biological organic fertilizer comprises raw materials comprising 10-15 pts. wt. ammonium sulfate, 15-20 pts. wt. urea, 35-40 pts. wt. potassium chloride, 30-40 pts. wt. monoammonium phosphate, 2-3 pts. wt. humic acid, 1-2 pts. wt. bentonite, 0.2-0.4 pts. wt. sepiolite powder, 1-2 pts. wt. shrimp shell powder, 0.1-0.2 pts. wt. nanocarbon powder, 0.1-0.2 pts. wt. boric acid, 0.1-0.3 pts. wt. ammonium molybdate, and 1-2 pts. wt. binding agent. The binding agent comprises raw materials comprising 30-40 pts. wt. rice starch, 4-6 pts. wt. yeast, 4-6 pts. wt. maltose, 50-60 pts. wt. water, 0.001-0.004 pts. wt. sodium selenite, 2-3 pts. wt. potassium hydroxide, 0.2-0.4 pts. wt. borax, and 0.1-0.2 pts. wt. tributyl phosphate. The binding agent is prepared by (a) taking rice starch, selenium, maltose and water to obtain mixture, fermenting the mixture at 28-31 degrees C for 23-25 hours, adding 4-5 pts. wt. selenium to the mixture for every 2-3 hours, and then adding 1 pt. wt. sodium selenite for total culturing time of 45-50 hours, (b) adding potassium hydroxide and borax to fermented product, and mixing added materials at 30-35 degrees C for 1-1.5 hours at a stirring speed of 2 times per minute, (c) mixing tributyl phosphate to mixture of step (b) to obtain semifinished product, and (d) drying the semifinished product at 80-90 degrees C, crushing dried product to obtain binding agent and mixing potassium chloride powder and 9-12 wt.% starch to the binding agent. An INDEPENDENT CLAIM is included for method for preparing the fermented biological organic fertilizer, which involves mixing binding agent and bentonite to obtain mixture, adding 3-5 wt.% vinasse and 1-2 wt.% sucrose to the mixture, mixing the materials at 25-35 degrees C for 45-50 hours, adding remaining raw materials to the mixture, stirring the materials at 50-60 degrees C to obtain final mixture, uniformly granulating the final mixture, and drying granules at 65-75 degrees C to obtain fermented biological organic fertilizer.
