Where to get gypsum

Pulverized Organic Gypsum. Pulverized Damp Gypsum. Pulverized Damp Organic Gypsum. USA Gypsum agricultural products provide sulfur and calcium for a more healthy soil for your crops.

Calcium improves soil structure, aeration and drainage, resulting in increased water infiltration and reduced soil surface crusting and improved seedling emergence. Gypsum also helps break up compacted soil critical for increasing rooting depth, stabilizes organic matter and decreases nitrogen loss to the atmosphere.

Agricultural Gypsum Calcium Sulfate — CaSo 4 Building more productive soil naturally Agricultural gypsum works as a soil amendment, conditioner and fertilizer to improve the soil. Is gypsum a cost-effective solution for your calcium and sulfur needs? Check soil tests and consult your agronomist. Gypsum is a mineral that is naturally found concentrated in various places and can be mined out of the ground. This can be a real benefit in agriculture.

We also determined that it is safe for agricultural use through many studies. Reusing it for agricultural purposes, instead of putting it in landfills, provides multiple wins. Gypsum is high in both calcium and sulfur. In addition, the chemical formula of gypsum makes those nutrients more available to plants than some other common sources of these nutrients. Chemically speaking, gypsum is calcium sulfate.

Its use is often confused with that of lime, which is calcium carbonate. Gypsum will change soil pH very slightly, yet it can promote better root development of crops, especially in acid soils, even without a big pH change.

This is because the gypsum counteracts the toxic effect of soluble aluminum on root development. But when soil becomes acidic, the aluminum is available to plants—and it can stunt or kill them. Another bonus of gypsum is that it is a moderately-soluble mineral. This means the calcium can move further down into the soil than the calcium from lime calcium carbonate.

This can inhibit aluminum uptake at depth and promote deeper rooting of plants. When roots are more abundant and can grow deeper into the soil profile, they can take up more water and nutrients, even during the drier periods of a growing season. Although moderately soluble, gypsum can be an excellent source of sulfur over several growing seasons. Research found that the sulfur is available not only in the year applied, but can continue to supply sulfur for one or two years after, depending on the initial application rate.

Gypsum as a sulfur fertilizer has benefitted corn, soybean, canola, and alfalfa. Gypsum can also help improve soil structure. Many of us look at soil as a uniform, static substance. In reality, soil is a mixture of inorganic particles, organic particles, and a complex mixture of pore spaces, water, and soil microbes. Its composition changes through weather events like rainstorms, by tillage, or as plants pull nutrients for growth.

Farmers have to manage their soil well in order to maintain good crop yields year after year.
