Abstract: Agriculture has failed to be sustainable several times in the history of the world because of soil failure (Rush, 1987). Irrigated land eventually leads to sodicity and salinity unless extreme care is taken. Gypsum is a key ingredient for the maintenance of agriculture on many types of soils and over a wide pH range including sodicity. Waste …

The plant became operational in January 2015 and the production capacity is aimed to continue …
more soluble when applied to soil at a neutral pH (EPRI, 2006). Gypsum's solubility allows movement of Ca and S through the soil profile into rooting zones (Chen and Dick, 2011). In addition to supplying Ca and S for plant nutrition, gypsum can be used as a soil conditioner to improve physical and chemical
The fertilizer giant wants to use 1,200 tons of its phosphate waste byproduct in a test roadway, records show.
Recycling construction and demolition waste is an ongoing global conversation. The following reflects current efforts as well as the concerns, challenges, and opportunities associated with recycling construction and demolition waste gypsum panels. Gypsum panels currently incorporate recycled materials. Paper facers have been made from …
This article discusses the quality and quantities of limestone requirements for Flue Gas Desulfurisation (FGD) with expected quality of synthetic gypsum (SG) generated from power plants. As this development is a win-win situation for power and cement, various possibilities of collaboration between these two major industries are discussed in …
Not all Australian plants need gypsum adding, and if you want to save yourself time, money, and effort, there are some great natives that grow perfectly well on clay soil without any amendment with gypsum or other additives. ... If you're stuck with clay soil, whether on large-scale projects, or domestic gardens, gypsum will likely offer …

Why You Should Use Gypsum . You should use a gypsum soil amendment if your soil's salinity is too high. That means that it contains too much salt (sodium chloride). If you're not sure whether your soil has high salinity, do a salinity test (a good lab-based soil test kit will tell you the salt level with accuracy.
