Potassium Sulfate

Potassium Sulfate is a high-grade potassium fertilizer containing high Sulfur, high Potassium and low Chlorine. It is mainly used for grapes, citrus, flowers, tobacco and anaerobic crops. It is also used for cutting and cultivating delicate crops (such as greenhouse cultivation, hydroponic crops, etc.) considered as a premium fertilizer.

Features Product Description

Benefits to plants:
Increase fructose content, Reduce Chlorine hazards, More vivid color, Add flavor, Improve yield

The solubility of SOP soluble specification exceeds 99.7%, which is suitable for open field fertilization, such as central spraying.
Oily crops have a higher demand for Sulfur. The use of Sulfur in soybeans and peanuts can promote the fixation of Nitrogen, and the use of Potassium Sulfate in linseed will result in higher oil content.
Potassium Sulfate can give tobacco leaves a good color and excellent burning quality
