Soil Benefits

USA Gypsum is 21% calcium and 17% sulfate. It is one of those rare materials that perform in all three categories of soil treatment: an amendment, conditioner and fertilizer. It is a fast release source of sulfur and calcium. When dissolved it releases an equal proportion of calcium and sulfate. Gypsum is 100% more soluble than lime! Increases calcium without effecting pH.

What will USA Gypsum do for my soil? Gypsum interacts with water to reduce crusting. Gypsum loosens clay and compacted soil, improving the structure. Great for no-till! Improved soil aggregation and permeability will allow easier penetration of surface applied fertilizers. Provides a low cost remedy for acid, sodic and erosion prone soils.

What will USA Gypsum do for my crops, lawn or garden? Plants need calcium to produce early root growth, encourage production and increase calcium content of the crop. Gypsum prevents some plant disease in produce such as scab or bitter pit.

Application: 1-2 ton per acre.

Composting Amendment

USA Gypsum works by preventing fermenting compost from giving off large quantities of nitrogen in the form of ammonia. Gypsum ties up this nitrogen as ammonium sulfate. Retaining nitrogen reduces unpleasant odors. Gypsum also improves compost aeration, and enhances the microbial growth. Maximize use of recycled waste!

Application: 300 lbs. per ton of compost. Ad as compost accumulates.
