Organic Calcium Sulfate Dihydrate (CaSO4 + 2H20 “Gypsum”)

“There is not an acre of irrigated land that does not require Calcium Sulfate Dihydrate.” 
– Brent Rouppet, PHD Soil Scientist



Areas treated with Calcium Sulfate Dihydrate or gypsum in your garden or agricultural land would require as much as 30% less irrigation water. This is largely the result of greater permeability and water integration due to improved soil structure when using gypsum. We are are international suppliers of organic Calcium Sulfate Dihydrate.


Calcium Sulfate or gypsum offers a vital source of Calcium enrichment and is a functional amendment for food, beverage, and pharmaceutical products. Though an amendment instead of a classic fertilizer, its benefits run the product spectrum.


Each dollar spent by growers on gypsum can yield up to 863% in ROI. Typical yield increases after using this gypsum amendment range from approximately 80% for corn plants to around 53% for soybeans after gypsum application. Optimal structure dramatically increases plant growth and gypsum is a needed soil nutrient.


Calcium Sulfate Dihydrate (gypsum) when used as a soil amendment instead of as a fertilizer increases nutrient and water infiltration and percolation in soil in bulk thereby reducing the likelihood of run off of added or natural nitrogen or phosphorous. It also decreases harmful carbon and nitrous oxide emissions by reducing the need for tillage which enables effective balance in soil of of nutrient inputs, such as NPK.


Calcium Sulfate Dihydrate (gypsum) is the only known natural solution for soils high in sodium (Na) and magnesium (Mg). Such soils are common in lower rainfall parts of the world, especially where irrigation is the primary source of water. Soils with a high mineral salts demonstrate severe limitations on crop health and yields. Eco-Gem are suppliers worldwide for gypsum amendments that return soil to health.

Gypsum Soil


Gypsum, also called selenite, is a micronutrient soils amendment that has been used by farmers, gardeners and consumer product manufacturers for decades. Among other things, gypsum amendments improve soils and soil structure and helps stimulate root growth.


Sadly, with a rapidly growing global population, our world is facing prodigious challenges including garden, agricultural land and soil loss. This condition can be improved and overcome in time by correcting poor soil conditions with gypsum soil amendments to remediate sodic soils, increase soil water retention and provide calcium and sulfur as a crop nutrient source.

Specifically, gypsum soil amendment provides tremendous benefits to soil properties in gardens and agricultural land by:

Loosening tightly compacted soil to improve soil structure through adding gypsum

Providing aeration and permeability

Decreasing wind erosion of soil and soil structure

We simply cannot emphasize enough the tremendous common benefits of essential gypsum soil amendment and conditioner to improve the sustainability of all irrigated soil.
