Beschreibung
Zusammenfassung:	A fertilizer composition includes coated urea ammonium sulfate particles, the coated urea ammonium sulfate particles including: a urea core; and a coating on the urea core, wherein the coating includes ammonium sulfate. Methods for making coated urea ammonium sulfate particles include: (a) combining urea particles with sulfuric acid to form intermediate particles including an intermediate coating, wherein the intermediate coating includes urea sulfate; and (b) combining the intermediate particles with ammonia or an ammonium compound to form the coated urea ammonium sulfate particles, wherein the coated urea ammonium sulfate particles include a urea core and a coating including ammonium sulfate on the urea core.
