Diamond K Ultra Fines — Sulfate of Potash
Its primary elements are 52% potash (K2O) and 18% sulfate (SO4). The superior fine grain, minus 200 mesh, and organically certified, SOP is designed to be uniformly metered, dissolved and injected directly into an irrigation system.

To make a 6% liquid potash solution:

Dissolve 1 pound of Sulfate of Potash powder in 1 gallon of warm to hot water and shake/stir well.

Sulfate of Potash is an enriched source of potassium, which aids in developing plant vigor and disease resistance. 

  • Source of Sulfur
    Sulfate of Potash contributes much needed sulfur as sulfate, a secondary element which aids in developing dark green color.
  • Safe
    Sulfate of Potash has a very low salt index. Sulfate of potash is virtually chloride free and thus has a lower burn potential than either muriate of potash or sulfate of potash magnesia.
