NOVELTY - Organic fertilizer composition comprises (part by weight): amino acid mixed materials (18-20), potassium chloride (1-35), boric acid (0.2-0.5), manganese sulfate (0.2-0.5), zinc sulfate (0.2-0.5), urea (10-20), calcium superphosphate (10-15), magnesium sulfate (10-15), copper sulfate (0.2-0.5), ammonium molybdate (0.2-0.5), livestock manure (0.2-0.5), starter culture (0.1-0.5) and water (15-20). The amino acid mixed material is composed of silicate water solution as the hydrolytic agent, animals and plants protein material (50-70 wt.%) and humic acid (30-50 wt.%).    USE - As organic fertilizer (claimed).    ADVANTAGE - The present organic fertilizer uses the synergetic effect of the raw material components to have all merits of high activity e.g. well fertilizer efficiency without hardening soil and by killing pathogenic bacteria egg. The fertilizer nutrient content of 30-40%, organic matter content of 25-30%, and water-soluble silicon dioxide content of 5-10%. After fertilizing the soil nutrient can self-adjust the storage and energy releasing in the soil so as to have moderate release on the crop. The organic compound fertilizer is prepared by simple, cost-effective, eco-friendly and easy to operate method.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the fertilizer composition involving (a1) mixing silicate and water in a proportion of 1:2 parts by weight, heating by steam to 60-70 degrees C and reacting for 4 hours at low pressure to obtain silicate water solution; heating the prepared silicate water solution to 60 degrees C, heating and adding animal and plants protein material and humic acid, heating to 100-110 degrees C until the animal and plant protein material and humic acid dissolved completely, continuously stirring for 2 hours; uniformly mixing the potassium chloride, boric acid, manganese sulfate, zinc sulfate, urea, calcium sulfate, magnesium sulfate, copper sulfate, ferrous sulfate and ammonium molybdate to obtain amino acid raw materials; adding the mixture of the inorganic elements and water into the amino acid mixed materials, raising the temperature to 100-110 degrees C, stirring for 2 hours, then cooling to normal temperature, and then adding livestock manure and culture to fully ferment the fermentation material 1-2 times per day in the fermentation period of 5-10 days, and drying to obtain the product.
