An organic fertilizer using fructose residue is prepared by (A) mixing 40-60 wt.% fructose residue containing 0.5-20 wt.% diatomaceous earth, prescribed amount of corn sulfonate liquid and 20-60 wt.% animal dung, and (B) fermenting the mixture. The fructose residue, which is produced as byproduct from extractive filtration of fructose on diatomaceous earth, contains 6.72 % nitrogen, 2.10 % phosphoric acid, 0.47 % potassium, 0.22 % calcium, 0.94 % magnesium, 15.527 ppm iron, 43.1 ppm manganese, and 0.54 ppm sodium. Diatomaceous earth as filtering aid contains alumina, silica, zirconia, titania, magnesia etc., emitting far-infrared radiation at high temp. which serves plant growh.
