Super Sulfur Potash 50 lb bag

Super Sulfur Potash 0-0-.5 (screened to ⅛" minus) packs a one-two punch. First, its blend of soil-acidifying agricultural minerals rapidly produce acid to lower the pH of alkali soils. Second, its residual compounds provide long-term control of soil pH. Contains potassium, multiple forms of sulfur, gypsum, and trace minerals. Additive-free and mined from a 100% natural volcanic source. Applied during ground preparation.
