USE - The fertilizer is useful for supplying nutritional element to strawberry plant (claimed), and improving soil fertility.    ADVANTAGE - The fertilizer is cost-effective, enables to protect soil, increase crop yield and reduce irrigation and provides balanced nutrition to plants.    DETAILED DESCRIPTION - Fertilizer comprises 12-14 pts. wt. pine needle powder, 34-37 pts. wt. cow dung, 30-32 pts. wt. sheep manure, 30-31 pts. wt. sesame seed cake, 14-18 pts. wt. biogas residue, 10-15 pts. wt. calcium superphosphate, 0.4-0.6 pts. wt. silica, 0.3-0.6 pts. wt. sodium tripolyphosphate, 16-19 pts. wt. potassium pyrophosphate, 7-11 pts. wt. fishmeal, 9-14 pts. wt. shell powder, 0.4-0.8 pts. wt. acrylamide, 4-7 pts. wt. nano-modified attapulgite, 13-18 pts. wt. ammonium persulfate, 11-19 pts. wt. carnauba wax, 5-8 pts. wt. effective microorganism, 8-11 pts. wt. soil modifying agent, and remainder water. The soil modifying agent comprises 0.4-1 pts. wt. acrylic acid, 0.3-1 pts. wt. nanocarbon, 1-2 pts. wt. ammonium sulfate, 0.5-1 pts. wt. enriched yeast, 1-2 pts. wt. calcium citrate, 0.3-1 pts. wt. zinc gluconate, 0.2-0.6 pts. wt. castor oil, 13-15 pts. wt. tetraethyl orthosilicate, 0.3-0.8 pts. wt. citric acid, 8-10 pts. wt. bentonite, 2-4 pts. wt. ethyl cellulose, 1-2 pts. wt. magnesium sulfate, and 0.2-0.6 pts. wt. bamboo fiber. The soil modifying agent is prepared by weighing the above-mentioned raw materials, mixing ammonium sulfate, enriched yeast, calcium citrate, zinc gluconate, magnesium sulfate, and tetraethyl orthosilicate, heating mixture at 40-50 degrees C, adding acrylic acid, manganese sulfate, nanocarbon, citric acid, bentonite and bamboo fiber, stirring mixture, concentrating solution, granulating, drying granules, adding 10 times of ethyl cellulose to coating pan, adding castor oil, mixing uniformly, spraying mixture on granules, drying granules to remove ethanol, sieving granules and drying at room temperature. An INDEPENDENT CLAIM is included for method for preparing the fertilizer, which involves (a) mixing pine needle powder, cow dung, sheep manure, sesame seed cake, biogas residue, fishmeal, shell powder, and effective microorganism, maintaining moisture content at 41-45%, stirring uniformly, sealing container, performing anaerobic fermentation at room temperature for 22-27 days (turning the mixture 3-4 times once every day), drying fermented mixture and sieving dried mixture using 200-400 mesh sieve, (b) mixing nano-modified attapulgite, carnauba wax, and soil modifying agent, grinding mixture, adding remaining raw materials, and mixing mixture uniformly, and granulating mixture obtained in step (a) to obtain granules, and (c) adding granules obtained in step (b) into drum granulator, spraying mixture obtained in step (b) on granules uniformly, stirring uniformly, and cooling granules to room temperature.
