Ammonium urea, a new type of nitrogen fertilizer with high utilization rate, entered the farmland, which greatly improved the nitrogen use efficiency. Compared with urea, ammonium urea has the following advantages. One.

Potassium sulfate should be selected for sulfur-deficient soil, and potassium sulfate should also be applied in saline-alkali soil, not potassium chloride, so as to avoid increasing the content of soil chloride. Potassium sulfate should be selected for crops that are sensitive to chlorine, such as tobacco, potatoes, sweet potatoes, sugarcane, tea trees, oranges and so on. Potassium sulfate should also be used for sulfur-loving crops, such as onions, garlic and other vegetables.
