How to choose the right potassium fertilizer variety? The key lies in these four points
There are many types of nitrogen-containing fertilizers, such as urea, ammonium sulfate, ammonium bicarbonate, ammonium chloride, ammonium nitrate, etc. The utilization rate of various nitrogen fertilizers differs, and their effects are also different. A new type of nitrogen fertilizer with a high utilization rate - urea ammonium - has entered farmland, greatly improving the nitrogen fertilizer utilization rate. Compared with urea, urea ammonium has the following advantages. First, ...
Look at soil conditions. For sulfur-deficient soil, potassium sulfate should be chosen; potassium sulfate should also be applied in saline-alkali land, and potassium chloride should not be chosen, so as to avoid increasing the chloride ion content in the soil.Look at crop types. For chlorine-sensitive crops, such as tobacco, potato, sweet potato, sugarcane, tea plant, citrus, etc., potassium sulfate should be chosen. For sulfur-loving crops, such as onions, garlic and other vegetables, potassium sulfate should also be chosen.
Look at fertilizer price. Potassium sulfate is more expensive than potassium chloride, so apart from special reasons and requirements, potassium chloride should be chosen as much as possible under normal circumstances.
Look at irrigation conditions. In areas with irrigation conditions or abundant rainfall, as long as the soil drainage conditions are good, most crops can choose potassium chloride, and it will not have adverse effects on yield or variety.
