AUREA, 46, is, a, granular, nitrogen, fertilizer,, containing, 46%, of, Ureic, nitrogen,, treated, with, N--(nbutyl), thiophosphoric, triamide, (NBPt),, a, molecule, which, inhibits, the, urease, enzyme., this, enzyme,, in, nature,, is, produced, by, mushrooms, and, bacteria, present, in, the, soil, in, huge, quantities., immediately, after, top, dressing, application, urea, comes, in, contact, with, the, urease, enzyme, which, produces, by, hydrolysis, ammonia, carbonate,, causing, volatilization, of, ammonia, into, the, air., By, the, hydrolysis, also, groups, of, hydroxyl, OH, are, freed, up, which, cause, the, increase, of, the, pH, value, resulting, into, a, decline, of, the, alkaline, conditions, of, the, soil
AUREA, 34, is, a, slow, release, treated, granular, nitrogen, fertilizer,, containing, 23%, of, Ureic, and, 11%, of, Ammoniacal, nitrogen., the, ureic, nitrogen, is, treated, with, N-(nbutyl), thiophosphoric, triamide, (NBPt),, a, chemical, urease, inhibitor., this, treatment, slows, down, the, transformation, from, the, Ureic, nitrogen, to, ammonia, (highly, volatile)., As, Aurea, 34, contains, also, Ammoniacal, nitrogen, and, sulphuric, Anhydride, (30%), the, acidifying, effect, on, the, soil, is, enhanced.
Complex fertilizer, NPK granular water soluble liquid fertilizer and gel, urea with inhibitor of the ureasi, urea phosphate, urea.
