Beschreibung
Zusammenfassung:	Methods of forming a fertilizer composition having slow-release nitrogen compounds with a molten process are disclosed. The methods include mixing of a crystalline polyethylene wax with urea and formaldehyde to form a molten methylene urea mixture. The contents of the molten methylene urea mixture react to form slow-release nitrogen compounds. Fertilizer compositions formed of or including the slow-release nitrogen compounds are also disclosed. Se describen métodos para formar una composición fertilizante que tiene compuestos de nitrógeno de liberación retardada con un proceso de fusión. Los métodos incluyen mezclar una cera de polietileno cristalina con urea y formaldehído para formar una mezcla fundida de urea metileno. Los contenidos de la mezcla fundida de metileno urea reaccionan para formar compuestos de nitrógeno de liberación retardada. También se describen composiciones fertilizantes formadas de o que incluyen los compuestos de nitrógeno de liberación retardada.
