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 46):
A method for the manufacture of a homogeneous, solid, particulate, urea ammonium sulphate-based composition according to  claim 25 , the method comprising the steps of:\n 1) providing a urea ammonium sulphate material; 2) adding from 0.0001 to 5 weight %, 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, selected from the group of metal oxides, such as calcium oxide, magnesium oxide, zinc oxide, sodium oxide, aluminium oxide, barium oxide and copper oxide; carbonates, such as calcium carbonate, sodium carbonate, ammonium carbonate, barium carbonate; hydroxides, such as aluminium hydroxide, ammonium hydroxide, sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide, iron hydroxide, barium hydroxide and tetraalkyl/aryl ammonium hydroxides; and acetates, such as sodium acetate, ammonium acetate, magnesium acetate, zinc acetate and barium acetate, and any mixture thereof; or, selected from the group of organic bases, such as ammonia; amines, such as triethylamine, ethanolamine and triethanolamine; amides, such as sodium amide and magnesium diamide; adenines; amidines; guanidines; anilines; carbamates; thiazoles; triazoles; pyridines; imidazoles; benzimidazoles; histidines; phosphazenes, and any mixture thereof;\n 3) adding a urease inhibitor in solid particulate or liquid form, preferably wherein the urease inhibitor is N-(n-butyl) thiophosphoric triamide (nBTPT); and \n 4) optionally, applying a coating that is able to increase at least the water repellence and/or anticaking properties of urea ammonium sulphate, preferably wherein said coating is as disclosed in EP 0768993 A1; \n wherein the steps 2), 3) and 4) can be interchanged or wherein steps 2), 3) and 4) can be performed simultaneously.
