Gypsum and Clay Soils - douggreensgarden

2015-12-28  Smaller soil particles lump together (floculate) to form tiny soil balls. In clay soils, this has not happened to any degree. Gypsum aids the clay particles to lump together (it’s a chemical reaction/bonding kind of thing beyond the scope of this page) Bottom line – adding gypsum helps the tiny particles to group together to form larger ...

2014-6-1  Very soft clay soil samples were collected from the construction site of an embankment project located in Gunma Prefecture, Japan. Soil samples were taken from a depth of 0.5–1 m below the original ground level. The samples were stored in a controlled room in plastic bags to maintain the water content until the samples were required for testing.

Improving Soil With Gypsum - Garden.org

Gypsum can reclaim high-sodium or "sodic" soils. Soils with a high proportion of exchangeable sodium (Na+) lose structure. Once soil is tightly packed, water and air penetration is reduced and root growth suffers. Water often puddles on the surface of these soils. To revitalize sodic soils, incorporate gypsum into the soil and then apply six or ...
