The utilization rate of zinc humic acid fertilizer is higher than that of ordinary fertilizer. Zinc humic acid fertilizer is a zinc humic acid synergist added to the common fertilizer production process to improve the utilization of fertilizer. The nitrogen content of zinc humic acid urea is 46%, and the nitrogen content of common urea is 46.2%. The difference between the two is small, but the ammonia volatilization inhibition rate of zinc humic acid urea is ≥10%, which means that ammonia volatilization is significantly reduced. high. The nutrient content of diammonium zinc citrate and common diammonium is exactly the same, but zinc humic acid can effectively reduce the fixation of phosphorus in the soil and greatly increase the activity and utilization of phosphorus.
