Choose potassium fertilizer varieties to "four look"

Potassium sulphate should be used for soils with soil conditions and sulfur deficiency. Potassium sulphate should also be applied to saline-alkali soils. Potassium chloride should not be used to avoid increasing the chloride ion content of soil.

Look for crops that are sensitive to chlorine, such as tobacco, potatoes, sweet potatoes, sugar cane, tea trees, citrus, etc. Potassium sulphate should also be used for vegetables that are sulphur-like, such as onion and garlic.

See the price of fertilizer, the price of potassium sulphate is more expensive than potassium chloride, so in addition to special reasons and requirements, potassium chloride should be used in general.

In areas where irrigation conditions are irrigated or rainy, potassium chloride is used in most crops as long as the soil is well drained, with no adverse effects on yield and variety.
