Abstract:
     The content of carbon and ammonium in composite fertilizer for this invention is 65-85%, two dimensioenal or three dimensional composite fertilizer is made up through addition of potassium chloride, phosphammoium or potassium sulfate. Calcium magnesium phosphat is used as stabilizator. calcium oxide and magnesium chloride in content and phosphammonium are reacted, free water in carbon and ammonium is converted into water of crystallization, so that chemical drying at atmospheric temperature is generated to improve stability of fertilizer. A little binder can be added into. 1-4mm graininess of fertilizer is greater than 80%, mean compression strength of grainines (2-2.8mm graininess) is greater than 8N, the cost is lower than conventional fertilizer.
