Which crops are suitable for potassium sulfate and potassium chloride application?
Which crops are suitable for potassium sulfate or potassium chloride application? Please give an introduction. Crop chloride tolerance refers to a crop's ability to endure chloride applied to the roots without suffering toxicity; the lower the concentration at which toxicity begins, the poorer the chloride tolerance. Among common crops, those with strong chloride tolerance include sugar beet, spinach, foxtail millet, kenaf, radish, chrysanthemum, rice, sorghum...

Crop chloride tolerance refers to a crop's ability to endure chloride applied to the roots without suffering toxicity; the lower the concentration at which toxicity begins, the poorer the chloride tolerance. Among common crops, those with strong chloride tolerance include sugar beet, spinach, foxtail millet, kenaf, radish, chrysanthemum, rice, sorghum, cotton, rapeseed, cucumber, barley, etc., for which potassium chloride can be used; those with moderate chloride tolerance include wheat, corn, tomato, eggplant, soybean, broad bean, pea, cabbage, sugarcane, peanut, celery, flax, chili pepper, Chinese cabbage, small rapeseed, strawberry, cauliflower, etc., for which a moderate amount of potassium chloride can be applied in the base fertilizer; those with weak chloride tolerance include potato, sweet potato, grape, apple, amaranth, lettuce, flue-cured tobacco, etc., for which potassium sulfate should be used.
In addition, local rainfall and irrigation conditions should also be considered. For example, in arid regions, soil salinization is relatively common, so potassium chloride should generally be applied sparingly or not at all. Greenhouse vegetable plots under closed management have high salt content and are also unsuitable for potassium chloride application. In areas with abundant rain or irrigation conditions, a moderate amount of potassium chloride can be applied in the base fertilizer, because chloride in the soil is easily leached away with water.
