摘要：
A particulate sulfur-containing fertilizer comprising a uniform dispersion of sulfur and at least one member selected from the group consisting of ammonium sulfate, ammonium phosphate and mixtures thereof, the sulfur having an average particle size of less than about 100 'mu'm. A process for producing the granulated sulfur-containing fertilizer is described. The process comprises the steps of: (i) providing a first stream comprising ammonia; (ii) providing a second stream comprising at least one member selected from the group consisting of sulfuric acid, phosphoric acid and mixtures thereof; (iii) providing a third stream comprising an aqueous liquid; (iv) mixing the first stream, the second stream and the third stream to form a liquid reaction mixture; (v) feeding the liquid reaction mixture to a mixer; (vi) feeding a fourth stream comprising molten sulfur to the mixer prior to solidification of the reaction mixture; and (vii) solidifying the homogenized melt to produce the granulated sulfur-containing ferti
