IMPROVED UREA AMMONIUM SULPHATE-BASED COMPOSITION AND METHOD FOR THE MANUFACTURE THEREOF

摘要

This present disclosure relates to a solid, particulate, urea ammonium sulphate-based composition, further comprising one or more alkaline or alkaline-forming inorganic or organic compounds that are able to interact with ammonium sulphate, a urease inhibitor of the type phosphoric triamide, and a cation source comprising a cation selected from the group consisting of Fe²⁺, Fe³⁺, Mn²⁺, Zn²⁺, Cu⁺, Cu²⁺, Ni²⁺, Ag⁺, Pt²⁺, Ru²⁺, Co³⁺ and Cr³⁺. The invention further relates to a method for the manufacture of a solid, particulate urea ammonium sulphate-based composition comprising urea, ammonium sulphate, a urease inhibitor of the type phosphoric triamide, in particular N-(n-butyl) thiophosphoric triamide (nBTPT), one or more alkaline or alkaline-forming inorganic or organic compounds and a cation source. The product is in particular suitable for use as a fertilizer.
