DETAILED DESCRIPTION - Alkaline eco-friendly fertilizer comprises 20-28 pts. wt. bone meal, 10-15 pts. wt. river sand, 40-55 pts. wt. castor cake product, 55-70 pts. wt. soybean meal, 20-30 pts. wt. walnut, 15-20 pts. wt. gypsum powder, 20-24 pts. wt. kaolin, 10-20 pts. wt. flour, 3-4 pts. wt. beneficial microorganism bacteria, 2-3 pts. wt. agar, 12-16 pts. wt. urea, 10-14 pts. wt. potash fertilizer, 12-15 pts. wt. calcium-magnesium-phosphate fertilizer, 8-12 pts. wt. sodium bicarbonate, 15-20 pts. wt. calcium oxide, 3-4 pts. wt. coating agent and balanced amount of water. Coating agent comprises 1-2 pts. wt. divinylbenzene, 4-6 pts. wt. calcium oxide, 3-5 pts. wt. melamine formaldehyde resin, 6-9 pts. wt. isopropyl alcohol, 3-5 pts. wt. bamboo carbon powder, 2-4 pts. wt. acetic acid, 1-2 pts. wt. glycerol, 8-10 pts. wt. limestone powder, 0.5-1 pts. wt. sulfuric acid and balanced amount of water. Coating agent is prepared by diluting isopropyl alcohol with water (3-4 times) to obtain a solution. Remaining components are added in the solution and heated with stirring to dissolve to obtain emulsion. Emulsion is dried and concentrated. An INDEPENDENT CLAIM is included for a method for preparing alkaline eco-friendly fertilizer, which involves:    (A) mixing and crushing castor, soybean and walnut core, and then soaking with water for 2-3 days;    (B) grinding river sand, and adding gypsum powder and bone powder with soaked product to obtain paste;    (C) soaking urea, potash fertilizer, calcium-magnesium-phosphate fertilizer and sodium bicarbonate with water (4-6 times), and then heating for 30-40 minutes;    (D) adding soda lime with obtained product, stirring it, and then drying and granulating to obtain granules; and    (E) spraying the coating agent on surface of granules at 60-70 degrees C, and then drying for 10-15 minutes.
