NOVELTY - A slow release compound compost contains full capacity of organics and inorganics, where the compost is obtained by mixing processed slow release manure of nitrogen, phosphorus and potassium, and organics and regular manure of nitrogen, phosphorus and potassium, where the processed manure of nitrogen, phosphorus and potassium is a product from polymerization of urea and formaldehyde, and polymerization of monoammonium phosphate and potassium chloride.    USE - As a slow release organic and inorganic fertilizer.    ADVANTAGE - The compound provides various nutrients needed in different phases of crop growth; improves the availability of the compost and the quality of the crop products, and diminishes the costs and increases the crop production; and is selfdegradable in soil and provides the effective nutrient according to growth characteristics.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the slow release compound, involving: (1) determining the formula, calculating the dosage for basic manures and trace elements according to the overall balanced nutritional requirements of crops in different phases of growth, having urea and formaldehyde polymerized with routine method, and monoammonium phosphate and potassium chloride being polymerized the same way to prepare slow release manure of potassium and phosphorus, saving obtained manure for later use; (2) having the basic manure pre-smashed and mixed with the slow release manure obtained from step 1), organics and trace elements, adding in resin of high hydroscopicity, saving the mixture for further use, where the organics are danty, sodium or potassium humate, tobacco wastes, rapeseed, perpolitiones oryzae, feces of livestock, solidified solution of alcoholic fermentation and plant straw, where the trace element is supplied from manure of molybdenum, boron, manganese, zinc, copper, iron and chlorine; (3) having the evenly mixed material granulized, desiccated and sieved to obtain the compost.
