(57) [Summary] [PROBLEMS] As a means for effectively utilizing waste blood of cattle, pigs, chickens, etc., iron chains contained in blood are eluted by lactic acid fermentation, adsorbed on zeolite, and dried. Provided is a technique for producing an organic fertilizer that exhibits an effect of improving soil. SOLUTION: Blood is used as fertilizer. The effect depends on the fertilizer components such as N, P, and K in the blood, but also has an effect of improving the soil by the iron chain. Iron complexes have the effect of generating active oxygen, decomposing humus, eliminating pathogenic viruses and aggregating soil. However, it is difficult to industrially separate and purify the iron chain because it is easily broken by spoilage. The present invention is to produce a zeolite substance having iron chain functionality by isolating and purifying heme iron which cannot be produced industrially from blood by a simple lactic acid fermentation method at low cost, adsorbing this on zeolite and drying it.
