Diammonium Phosphate (DAP) is one of the best chemical fertilizers used individually or in combination with other fertilizers or soil nutrients. It is usually produced through reaction of wet phosphoric acid with ammonia in a pipe or tank reactor followed by the granulation process [Becker, 1989]. When a pipe reactor is used the
Compound fertilizer can supply comprehensive nutrient for crops. The production process of compound fertilizer is to combine the main nutrient elements needed for crops (such as N, P, K and other trace elements) by chemical method, that is, gather the nitrogen fertilizer, phosphorus fertilizer, potash fertilizer and other chemicals together and make into particles which are suitable for farming.
