History of Selenite, a.k.a ‘Gypsum’ as a Soil Amendment

Selenite is the mineral name for mined calcium sulfate, again commonly known as ‘gypsum’. The use of gypsum in agriculture dates back to the 1500’s in Europe, when plaster workers noticed that the grass where they shook their clothes out appeared healthier. Perhaps the most famous correlation of gypsum’s use in agriculture dates to the time of Benjamin Franklin, who applied it as a fertilizer on his farm. Over the centuries since Franklin’s time, farmers have continued to use it and benefit from it. In the last 10 to 15 years, gypsum’s popularity as both a soil amendment and fertilizer is becoming recognized by agronomists and farmers worldwide.
