NHU’s potassium sulfate comes as colorless crystals or regular round grains, with good physical properties – little moisture absorption, not easy to clump, and easy to apply. These make it a good water-soluble potassium fertilizer. We have both powder and granule forms available. It is chlorine-free, of high quality and high efficiency. There have been extensive applications of potassium sulfate in the plantation of chlorine-sensitive crops such as tobacco, grape, sugar beet, tea tree, potato, flax and various fruit trees, to bring more benefits to agricultural production.
