New Process for Producing Compound Fertilizer
Lishui Prefectural Chemical Indus- trial  Co. ,   Ltd.   of
Zhejiang has suc-cessfully synthesized liquid ammonia with
phosphate fertilizer and potassic fertilizer into compound
fertilizer at an  atmospheric  temperature  and  pressure.
After being treated by auxiliaries,   liquid  ammonia  and
waste ammonia liquor are reacted in a reactor  to  get  an
ammonia rate of over 95%.  It  is  then  synthesized  with
phosphate fertilizer  and  potassic  fertilizer  into  NPK
compound fertilizer. Tests show that the product  conforms
with relevant standards of the state.  The  trial  use  in
farmlands, tea  gardens,   orchards  and  vegetable  plots
proves that the product has  an  effect  20%  higher  than
other fertilizer varieties.
