Product Brief Introduction: DAP is a water-soluble quick-acting fertilizer and the most dominant variety of high-concentration phosphate fertilizers. It is applicable to the nitrogen and phosphorus needs of various kinds of crops. There is less solid after it is dissolved. The content proportion between effective phosphorus (AP2O5) and total nitrogen (TN) is comparatively appropriate (around 2.56:1). It can be combined with urea, ammonium nitrate and ammonium chloride and is the ideal base manure for producing multi-nutrient compound fertilizers and BB fertilizer. DAP has good result on the output and income increase of grain crops and cash crops including paddy, wheat, corn, sorghum, cotton, gourds, fruits and vegetables. It can be extensively applied on many varieties of soil such as red earth, yellow earth, brown earth, yellow wet earth, black earth, cinnamon earth and purple earth etc. It is especially appropriate for dry areas with little rain in northwest, north and northeast China.
