TECHNOLOGY FOCUS - AGRICULTURE - Preferred Components: The natural mineral comprises calcined limestone. The natural mineral comprises apatite formed by natural polymerization of phosphoric anhydride and complex structures comprising large amount of nitrogen, calcium, and magnesium. The natural mineral is pulverized to obtain fine powder having particle size of 500-1000 mu m. The dry deposited sludge further comprises 20-50 parts weight of moisture absorbent for maintaining moisture content remained after natural drying of the natural mineral. Preferred Composition: The 100 parts weight of the organic fertilizer composition is added and mixed with 80-250 parts weight of the water to obtain liquid organic fertilizer composition. The obtained 100 parts weight of the liquid organic fertilizer composition comprising 5-40 parts weight of the sludge, natural minerals and moisture absorbent is added with 5-35 parts weight of biodegradable polymer to obtain mixture, and the mixture is molded in form of various shape and sizes to obtain solid organic fertilizer composition. Preferred Method: The limestone is subjected to calcination at 600-1100 degrees C for 30-120 minutes in kiln. The natural mineral comprising apatite is subjected to quantitative and qualitative analysis for confirming whether the apatite is formed by natural polymerization of phosphoric acid anhydride. The method involves performing sample fabrication of the natural minerals for changing various types of phosphate ions before being subjected to quantitative and qualitative analysis. The method involves (a) repeatedly subjecting natural minerals sample to heating and evaporation processes for 3-7 times, sequentially dissolving the sample in distilled water, hydrochloric acid, nitric acid, perchloric acid, and concentrated sulfuric acid, and again subjecting the sample to repeated heating and evaporation process for 2-5 times, and dissolving the sample in distilled water and hydrogen peroxide, (b) solidifying obtained naturally polymerized apatite by adding dark aqua regia, sodium nitrate and potassium nitrate until complete evaporation occurs and dryness is achieved after being subjected to heating process, (c) adding the hydrogen peroxide and distilled water to solidified sample obtained in the step (b), heating and evaporating the sample to obtain more solidified sample, and adding distilled water, potassium chloride and aqua regia to the solidified sample after completion of the evaporation process, and (d) processing the solidified sample in distilled water and hydrochloric acid for 20-30 hours. The method involves mixing all the raw materials, subjecting obtained mixture to fermentation process for 5-40 days, separating precipitated solid content from fermented mixture to obtain liquid mixture, concentrating the liquid mixture, drying mixture being concentrated up to 30-70%.
