ZINC-AMMONIUM PHOSPHATE FERTILIZERS |
摘要 |
A process of obtaining a co-granulate of zinc and ammonium phosphate having a N/P ratio of 0.6 - 1.9 which includes initially feeding ammonium phosphate in finely divided form with a zinc source such as zinc oxide or zinc sulphate into a granulator wherein ammonia may also be fed into the granulator to increase the N/P ratio. The co-granulate is then obtained after drying.
