Abstract:
The invention relates to a homogeneous, solid, particulate, urea ammonium sul¬phate-based composition comprising urea ammonium sulphate and a urease inhibitor of the type phosphoric triamide, wherein the urea ammonium sulphate-based composition is further characterized in that one or more of the following measures applies: a) it comprises 5 weight % or less, relative to the total weight of the composition, of one or more alkaline or alkaline-forming inorganic or organic compounds that is able to interact with ammonium sulphate; b) the urease inhibitor of the type phosphoric triamide is in a solid particulate form; c) an anticaking and/or moisture repellent coating is applied onto the urea am¬monium sulphate particulate material. The composition according to the invention has improved properties for reducing ammonia loss by urease activity in the soil and is in particular suitable as a ferti¬lizer. The invention further relates to a method for the manufacture of a homogeneous, solid, particulate urea ammonium sulphate-based composition comprising urea, ammonium sulphate and a urease inhibitor of the type phosphoric triamide, in particular N-(n-butyl) thiophosphoric triamide (nBTPT), as well as to a composi¬tion of kit of parts comprising: a) one or more alkaline or alkaline-forming inorganic compounds that is able to interact with ammonium sulphate; b) the urease inhibitor of the type phosphoric triamide in solid particulate or liquid form, preferably wherein the urease inhibitor is N-(n-butyl) thiophosphoric tri¬amide (nBTPT); c) optionally, one or more anticaking and/or moisture repellent compounds.

Claim (Index 41):
The urea ammonium sulphate-based composition according to  claim 40 , wherein the UAS is a co-granulated material, preferably obtained from melt-mixing molten urea and solid particulate ammonium sulphate, from compacting finely divided solid urea and ammonium sulphate powders, or from a chemical process for the production of urea from carbon dioxide and ammonia, wherein ammonia is neutralized to form ammonium sulphate (AS) in the urea melt or solution to produce UAS.
