Summary: | The invention relates to a process for preparing complex liquid fertilizers. According to the invention, the process consists in that, in a vessel provided with a stirring and heating system, water is mixed with potassium carbonate and superphosphoric acid, then, after the mixture homogenization, there are admixed urea and a solution having a nitrogen content of 32%, as well as ammonium nitrate, after which a solution of potassium, magnesium and ammonium polyhumates extracted from peat coal is added while stirring, the pH value is corrected to 6 and sulphate-based micro elements are admixed to obtain a complex fertilizer having a content of 5% potassium and magnesium polyhumates.
Invenţia se referă la un procedeu pentru obţinerea unor îngrăşăminte lichide complexe. Procedeul conform invenţiei constă din aceea că, într-un vas prevăzut cu sistem de agitare şi încălzire, se amestecă apă cu carbonat de potasiu şi acid superfosforic, după omogenizarea amestecului, se adaugă uree şi o soluţie având un conţinut de 32% azot, precum şi azotat de amoniu, după care se adaugă, sub agitare, o soluţie de polihumaţi de potasiu, magneziu şi amoniu, extraşi din turbă, se corectează valoareaH la 6, şi se adaugă microelemente pe bază se sulfaţi, din care rezultă un îngrăşământ complex, având 5% polihumaţi de potasiu şi magneziu. |
