Abstract:
     A one-pass applied multi-elemtn compound fertilizer is prepared from bentone, heavy calcium, potassium chloride and urea through granulating based on the heat from reaction between sulfuric acid and liquefied nitrogen, drying and cooling to obtain compound NPK fertilizer. It features less liquid phases and low viscosity during its preparing process (resulting in easy breaking and granulating), and modification of heavy calcium to reduce crystallized water for higher physical nature.
