NOVELTY - A magnetized slow-release fertilizer comprises 250-280 pts. wt. peanut cake powder, 8-10 pts. wt. zinc chloride, 14-18 pts. wt. potassium feldspar powder, 20-24 pts. wt. calcium superphosphate, 170-190 pts. wt. sawdust, 40-60 pts. wt. pomegranate peel powder, 40-60 pts. wt. pulverized coal ash, 75-85 pts. wt. pyrite ash, 25-27 pts. wt. cassava starch, 6-8 pts. wt. calcium acetate, 14-17 pts. wt. composite biological agent, and balance water. The composite biological agent comprises sulfate-reducing bacteria, heterotrophic iron-reducing bacteria and Bacillus subtilis.    USE - Magnetized slow-release fertilizer used for increasing crop absorbing capacity (claimed).    ADVANTAGE - The magnetized slow-release fertilizer can magnetize shallow layer soil, strengthens crop physiological potential and cell magnetic potential, adjusts crop's in vivo activity, causes magnetic chemical reactions and magnetic biological effects between soil and root crops, promotes absorption of nutrients by crops, improves crop metabolic activities such as synthesis and transformation of organic matter, promotes crop growth and development, and increases yield and quality.    DETAILED DESCRIPTION - A magnetized slow-release fertilizer comprises 250-280 pts. wt. peanut cake powder, 8-10 pts. wt. zinc chloride, 14-18 pts. wt. potassium feldspar powder, 20-24 pts. wt. calcium superphosphate, 170-190 pts. wt. sawdust, 40-60 pts. wt. pomegranate peel powder, 40-60 pts. wt. pulverized coal ash, 75-85 pts. wt. pyrite ash, 25-27 pts. wt. cassava starch, 6-8 pts. wt. calcium acetate, 14-17 pts. wt. composite biological agent, and balance water. The composite biological agent comprises sulfate-reducing bacteria, heterotrophic iron-reducing bacteria and Bacillus subtilis at ratio of 1:1:2. An INDEPENDENT CLAIM is included for preparation of magnetized slow-release fertilizer comprising:    (A) putting pulverized coal ash into high temperature furnace, calcining to 800-900 degrees C for 20 minutes, cooling, and taking out; putting pyrite ash into high temperature furnace, calcining to 450-550 degrees C for 30 minutes, cooling, and taking out; and mixing two products, adding more than 5 mm large particles magnet at weight ratio of 4:1, shaking for 30-40 minutes, and sieving through 80-100 mesh sieve to obtain magnetized calcined ash;    (B) adding peanut cake powder, sawdust and pomegranate peel powder into fermentation tank, fermenting for 20-25 days while controlling moisture to 30-40%, taking out, crushing, and separating fermentation broth and residue;    (C) adding residue with magnetized calcined ash, potassium feldspar powder and calcium superphosphate, stirring, granulating, adding into magnetizing machine, and magnetizing at magnetic field strength of 4000-5000 mT for 10-15 seconds to obtain magnetized particles;    (D) adding fermentation broth with cassava starch, mixing, heating to 50-60 degrees C for 10-20 minutes, cooling to room temperature, adding remaining raw materials except composite biological agent, heating to 60-70 degrees C, chelating for 30-50 minutes, cooling, adding composite biological agent, stirring, and placing into magnetizing machine, and magnetizing at magnetic field strength of 300-400 mT for 5 minutes to obtain magnetized solution; and    (E) coating into surface of magnetized particles using high pressure spray, low-temperature drying, weighing, packaging, and storing into warehouse away from iron-based metallic material.
