METHOD OF PRODUCTION OF COMPLEX FERTILISER |
| 摘要 |
FIELD: agriculture.SUBSTANCE: method of production of complex fertiliser comprises mixing phosphoric acid with urea, neutralisation of phosphate-urea solution with ammonia to obtain the pulp and subsequent granulation and drying of the finished product at a temperature no higher than 85°C. At that, prior to neutralisation in the phosphate-urea solution the MgO-containing compound is added in a ratio of MgO:PO=(0.02÷0.1):1.EFFECT: invention enables to provide granular compound fertilisers containing partially nitrogen in the amide form, having low caking ability and hygroscopicity.4 cl, 6 ex |
