A composite fertilizer composition which controls noxious microorganism is provided to control noxious microorganism in crops, to facilitate the growth of crops, to accomplish eco-friendly agriculture and to store the fertilizer stably for a long time by comprising high concentration silver ion stabilized with ammonia, sodium thiosulfate, potassium thiosulfate or amines. A composite fertilizer composition which controls noxious microorganism comprises: 0.1-10 parts by weight of nitrogen source, 0.1-10 parts by weight of water soluble phosphate acid, 0.1-10 parts by weight of water soluble potassium, 0.1-1.5 parts by weight of water soluble magnesium, 0.01-0.2 parts by weight of water soluble manganese, 0.01-0.1 parts by weight of water soluble boron, 0.01-0.2 parts by weight of water soluble iron, 0.00001-0.001 parts by weight of water soluble molybdenum, 0.01-0.1 parts by weight of water soluble zinc, 0.01-0.1 parts by weight of water soluble copper, and 0.1-1.5 parts by weight of water soluble lime with respect to 100 parts by weight of high concentration silver ion aqueous solution in which 5,000-500,000ppm of silver ion is stabilized with ammonia, sodium thiosulfate, potassium thiosulfate or amines. The nitrogen source is ammonia, ammonium nitrate or urea; the source for phosphate and potassium is potassium monophosphate, potassium diphosphate or potassium triphosphate; the source for magnesium is magnesium nitrate or magnesium sulphate; the source for boron is boric acid, borax or ammonium borate; the source for molybdenum is sodium molybdate or ammonium molybdate; the source for water soluble lime is potassium hydroxy carbonate, calcium sulphate, slacked lime or quicklime; and the sources for iron, zinc and copper is nitric acid ion, sulphate ion or chelate compound. |
