NOVELTY - Slow-release fertilizer comprises 4-5 pts. wt. phosphorus pentoxide, 6-7 pts. wt. potassium oxide, 15-25 pts. wt. soybean, 4-5 pts. wt. sugar, 3-5 pts. wt. calcium superphosphate, 10-15 pts. wt. ash, 3-4 pts. wt. calcium superphosphate, 22-28 pts. wt. fresh corn straw, 3-5 pts. wt. ammonium bicarbonate, 3-4 pts. wt. magnesium sulfate, 5-6 pts. wt. zeolite powder, 3-4 pts. wt. silicate, 6-8 pts. wt. quartz stone powder, 5-8 pts. wt. coconut shell powder, 40-50 pts. wt. pork waste, 30-40 pts. wt. soil conditioner and water (suitable amount).    USE - The slow-release fertilizer is useful for muskmelon (claimed).    ADVANTAGE - The fertilizer is cost-effective, and has long-lasting effect.    DETAILED DESCRIPTION - Slow-release fertilizer comprises 4-5 pts. wt. phosphorus pentoxide, 6-7 pts. wt. potassium oxide, 15-25 pts. wt. soybean, 4-5 pts. wt. sugar, 3-5 pts. wt. calcium superphosphate, 10-15 pts. wt. ash, 3-4 pts. wt. calcium superphosphate, 22-28 pts. wt. fresh corn straw, 3-5 pts. wt. ammonium bicarbonate, 3-4 pts. wt. magnesium sulfate, 5-6 pts. wt. zeolite powder, 3-4 pts. wt. silicate, 6-8 pts. wt. quartz stone powder, 5-8 pts. wt. coconut shell powder, 40-50 pts. wt. pork waste, 30-40 pts. wt. soil conditioner and water (suitable amount). The soil conditioner comprises 2-3 pts. wt. mica, 2-4 pts. wt. ammonium molybdate, 3-4 pts. wt. polyacrylic acid, 6-8 pts. wt. mud snail powder, 5-6 pts. wt. EDTA chelated manganese, 5-6 pts. wt. EDTA chelated magnesium, 5-6 pts. wt. EDTA chelating copper, 6-7 pts. wt. amino acid chelated iron, 6-7 pts. wt. amino acid chelated calcium, 20-30 pts. wt. seabird excrement, 3-4 pts. wt. phosphogypsum, 15-25 pts. wt. aquatic waste, 5-8 pts. wt. wood rot fungi residue, 5-6 pts. wt. ammonium dihydrogen phosphate, and 6-10 pts. wt. sugar cane fiber. The soil conditioner is prepared by drying the seabird excrement, adding the dried excrement to phosphogypsum, and mud snail powder, placed mixture in a sealed container, steam-heating the mixture for 40-60 minutes, cooling mixture to room temperature, adding mixture into fermentation tank, adding other raw materials into the fermentation tank, composting mixture for 5-6 days, turning once during the fermentation tank, preparing the fermented mixture into pellets with diameter of 3-5 mm, spraying water on the pellet, drying pellet, and cooling dried pellet. An INDEPENDENT CLAIM is included for method for preparing the fertilizer, which involves (a) placing pork waste in high temperature furnace, heating pork waste at 550-600 degrees C for 20-40 minutes, and crushing pork waste to obtain crude powder, (b) crushing cooked soybeans into powder, adding sugar, quartz powder and coconut shell powder to the crushed mixture, adding warm water of 50-70 degrees C, and stirring mixture, (c) composting fresh corn straw for 15-20 days, (d) mixing other raw materials, crushing mixture, fermenting mixture, and drying fermented product, and (e) mixing all products of steps (a)-(d), and spray-drying mixture.
