The invention relates to a solid, particulate homogeneous urea-based composition containing elemental sulfur and a phosphoric triamide-type urease inhibitor, wherein the elemental sulfur-containing urea-based composition is further characterized in that they apply. one or more of the following measures: (a) contains a content of 5% or less by weight of the total mass of the composition of one or more alkaline or alkaline inorganic or organic compounds； or b) has an anti-caking and / or moisture repellent coating. The composition according to the invention has improved properties for reducing ammonia loss by soil urease activity and is in particular suitable as a fertilizer. The invention further relates to a method for producing a homogeneous, solid, particulate urea-based composition containing urea, elemental sulfur and a phosphoric triamide-type urease inhibitor, in particular n- (n-butyl) triamide. thiophosphoric (nbtpt), as well as a composition of a component kit containing: (a) one or more alkaline or alkaline inorganic or organic compounds； b) the solid or liquid particulate phosphoric triamide-type urease inhibitor, wherein the urease inhibitor is thiophosphoric n- (n-butyl) triamide (nbtpt)； c) optionally one or more anti-caking and / or moisture repellent compounds.a invenção se refere a uma composição à base de ureia homogênea, sólida, particulada, contendo enxofre elementar e um inibidor da urease do tipo triamida fosfórica, em que a composição à base de ureia, contendo enxofre elementar, é ainda caracterizada por que se aplicam uma ou mais das seguintes medidas: a) contém um teor do 5 % ou inferior em massa, relativo à massa total da composição, de um ou mais compostos inorgânicos ou orgânicos alcalinos ou alcalígenos； ou b) possui um revestimento antiaglomerante e/ou repelente da umidade. a composição de acordo com a invenção tem propriedades melhoradas para reduzir a perda de amoníaco pela atividade da urease no solo e é, em particular, adequada como
