Zinc humic acid urea is an elemental fertilizer, containing only nitrogen, no phosphorus and potassium, and can be mixed with other fertilizers such as diammonium phosphate, superphosphate, potassium chloride, potassium sulfate, etc., so that it can meet crop nutrients. The demand can also play a synergy role between fertilizers to improve fertilizer efficiency. However, urea can not be mixed with grass ash, calcium magnesium phosphate fertilizer and other alkaline fertilizers or applied at the same time, because the urea must be transformed into ammonium nitrogen before it can be used by crops. Ammonium nitrogen under alkaline conditions, most of the nitrogen will become volatile ammonia. The correct approach is that in the summer and autumn, urea and alkaline fertilizers should be staggered for 3 to 4 days, and winter and spring should be staggered for 7 to 8 days. In addition, urea should not be mixed with ammonium bicarbonate.
