NOVELTY - Soil conditioner comprises (in parts weight): organic compost (100), nitrogen compound fertilizer (0.5-5), phosphate fertilizer (0.5-5), potassium fertilizer (1-10), microelement fertilizer (0.1-30), calcium fertilizer (1-10), mineral fertilizer (1-10), and microbial fertilizer (0.5-5).    USE - The soil conditioner is useful for wild soil.    ADVANTAGE - The soil conditioner improves soil environment by reorganizing physic-chemical property of soil, supplies nutrients to soil, promotes aggregation of soil, enhances water retention property and water permeability of soil, removes heavy metals in the soil and stabilizes outgrowth of plants from the soil.    DETAILED DESCRIPTION - Soil conditioner comprises (in parts weight): organic compost (100), nitrogen compound fertilizer (0.5-5), phosphate fertilizer (0.5-5), potassium fertilizer (1-10), microelement fertilizer (0.1-30), calcium fertilizer (1-10), mineral fertilizer (1-10), and microbial fertilizer (0.5-5). The organic compost has moisture content of 10-40% and organic matter and nitrogen ratio of 20-40. The organic compost is prepared by fermenting sawdust, vegetable components, animal organic materials, nature organic components, fowl droppings and butchery by-product using Bacillus sp. microbial mixture containing B.pumilus, B.subtilis, B.licheniformis and B.megaterium. The nitrogen compound fertilizer comprises one or more components chosen from ammonium sulfate, ammonium chloride, ammonium nitrate and urea. The phosphate fertilizer comprises one or more components chosen from superphosphate of lime, phosphate of lime, ammonium phosphate, soluble phosphate fertilizers and calcined phosphate fertilizers. The potassium fertilizer comprises one or more components chosen from potassium chloride, potassium sulfate, potassium nitrate and potassium carbonate. The microelement fertilizer comprises one or more components chosen from iron compound, aluminum compound, copper compound and manganese compound. The calcium fertilizer comprises one or more components chosen from calcium oxide, calcium hydroxide, calcium carbonate, and dolomite. The mineral fertilizer comprises one or more components chosen from zeolite, bentonite and vermiculite. The microbial fertilizer comprises one or more microorganism chosen from Tolypothrix sp., Anabaena sp., Chlamydomonas sp. and Chlorella sp.. An INDEPENDENT CLAIM is included for method for preparing the soil conditioner, which involves mixing the above-cited components uniformly.
