Our Gypsum plus soluble Humates is different from other gypsum products. Because of the formulation and added humates it requires 1/5 the amount as a traditional gypsum (i.e., gypsum applied at 5# per 1000sf comparable to traditional gypsum at 20# per 1000sf). Gypsum is for soils low in calcium but not requiring changes in pH, is pelletized and can be easily spread.

Gypsum is mined from ancient saltwater deposits in Michigan and elsewhere around the world, gypsum is marketed as an elixir for heavy clay soils and for its high content of approximately 22% calcium which grass plants use in quantities third only to nitrogen and potassium.

Application
Can be applied anytime during the year however the benefits of gypsum will be realized sooner if applied after aeration. Apply at rate of 5 – 10 lbs per 1000 square feet.
