Abstract
Invenţia se referă la un îngrăşământ pe bază de azotat de calciu şi la un procedeu de obţinere a acestuia. Ingrăşământul conform invenţiei conţine 0,1...5,0% S ca SO, 14...19% calciu solubil în apă, 16...21% calciu total şi 0...3,0% magneziu solubil în apă, procentele fiind în greutate. Procedeul de obţinere a îngrăşământului, conform invenţiei, constă în amestecarea gipsului solid şi/sau a unui mineral care conţine sulfat şi care reacţionează încet cu un îngrăşământ de azotat de calciu topit la o temperatură de 90...110°C, amestecul fiind ţinut la această temperatură timp de 3...15 min, obţinându-se îngrăşământul sub formă de particule, la o temperatură de 80...110°C.
