Potassium sulfate is a common potash fertilizer. It can improve crops ability of drought resistance, cold resistance, lodging resistance,and pest disease resistance. It can also promote flowering and fruiting, and better use of nitrogen to increase protein content, and promote the production of sugar and starch. Especially suitable for tobacco, sugarcane, potato, sweet potato, grape, tea tree and other high potassium crops and sulfur-like cruciferous crops (such as rapeseed, beans, etc.) .Increase the strength, fineness,color purity of cotton and hemp crop fiber.

Potassium sulfate must be combined with nitrogen and phosphorus fertilizers for fully effect.
1. Do not apply to the roots of crops, neither to stems and leaves.
2. Not recommended for use in paddy fields or soil with strong reduction
3. Must be applied with lime or calcium magnesium and phosphate fertilizers for long-term application on the acidic soil.
4. Better to apply in small amount or mixed with farmyard fertilizer for sandy soil.
5. Prevent rain and damage during storage and transportation.
