Can Gypsum Remediate Dense, Deflocculated Soils?

One of gypsum’s primary benefits as a soil amendment is that the addition of calcium will flocculate the soil. Flocculation causes soil particles to come together and form natural aggregates and peds that improves soil structure and porosity. When soil particles disperse (deflocculated soils), natural aggregates breakdown and disperse, damaging...

Soil pH…Does Gypsum Help? Read below to find out.

Calcium sulfate (or gypsum) is a soluble inorganic compound. Gypsum has been used for many years to improve aggregation and inhibit or overcome dispersion in sodic soils. One of the many misnomers about calcium sulfate, or gypsum, is that it can effect soil pH. That misnomer arises from the fact that limestone, another calcium-containing...

Salting the Earth – Counteract Contamination with Calcium Sulfate

“Salting the earth” was a practice of ancient conquering armies. They poisoned farmland with salt so that crops would not grow. To the best of my knowledge, no one has intentionally “salted the earth” for many years. However, there is much unintentional soil contamination. Major sources of contamination include irrigation...

What is Selenite?

Selenite is a naturally occurring crystalline mineral also known as gypsum or calcium sulfate. Despite the similarity in the words, selenite contains no significant amount of selenium. In its purest form, selenite is nearly transparent and colorless; however most mined selenite is whitish to opaque to brownish in color. EcoGEM’s...
