Product Description
Description:
Potassium sulphate is white or off-white crystallized powder or granular, tasting bitter and salty, soluble in water. It is almost free of chlorine, sodium and heavy metals. Aqueous solution shows weakly acidic and it can help improve the absorption of other cations, esp. trace elements. It can greatly meet any crop's need for potassium, and is applicable to all crops and in all stages, including flowering and maturity stages. It is widely used in fertigation, foliar spraying and drip hydroponics. It is a good fertilizer for tabacco, tomato, orange and grape trees. The application dosage is 5-15 kilo/mu according to different stages.
