NOVELTY - Producing organic chelate compound fertilizer (F1) involves treating solid keratin materials with an acid to obtain amino acid solution (S1); fermenting crop straw and peat using composite bacterial liquid and ammonia water to form active humic substance (S2); mixing antioxidant and inorganic salt with (S1) and (S2) to form a chelate product; adding nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and filler kaoline and granulating to form pellets of (F1).    USE - For producing organic chelate compound fertilizer (claimed).    ADVANTAGE - The process provides organic chelate compound fertilizer having high stability and high plant absorbing rate.    DETAILED DESCRIPTION - Producing organic chelate compound fertilizer involves    (A) subjecting solid keratin material to acidolysis using 15% hydrochloric acid and 20% dilute sulfuric acid solution, in weight ratio of 1:1-3:1-5 at 90-120 degrees C for 15-25 hours, followed by adding ammonia, and adjusting pH to 7-8 and filtering to obtain amino acid solution (S1);    (B) crushing peat and crop straw to a size of 20-60 meshes and mixing in a weight ratio of 2-3:1, then adding composite bacterial liquid and 15% ammonia water, stirring for 2 hours and then fermenting at 60-80 degrees C for 2 days, then adding 15% potassium hydroxide solution to adjust pH to 7-8 to obtain active humic substance (S2), where mixing ratio of straw, bacterial liquid and ammonia water is 1:0-0.3:0.05-0.1;    (C) mixing antioxidant and trace element inorganic salt (I) into a reaction kettle, closing the kettle, adding amino acid solution (S1) and humic substance (S2), adjusting pH to 5-7 by adding inorganic acid or inorganic alkali dilute solution, and carrying out chelation under saturated steam (0.6-0.9 MPa), at 60-80 degrees C for 0.5-1.2 hours to form corresponding chelate compound (C1), where weight ratio of (I):(S1):(S2) is 1:0.5-3:0.1-3 and weight ratio of antioxidant and metal salt is 1:1-2; and    (D) uniformly mixing chelated product (C1) with inorganic fertilizer material (that comprises nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and filler kaolin in weight ratio of 1.2-4.4:1.5-4.9:1.2-4.8:0.2-2); and putting into a granulator; adding ammonia and dilute sulfuric acid (H2SO4); spraying, followed by pelleting, granulating, drying, sieving, and surface processing to obtain organic chelate compound fertilizer, where weight ratio of ammonia:50% dilute H2SO4:inorganic fertilizer material:Chelate is 1-3:2-4:72.5-96.4:6.1-16.3.
