WebWhere gypsum is used to remediate high-Na soils, it generally results in the enhancement of soil physical properties — such as reducing bulk density, increasing permeability and water infiltration, and decreasing soil crusting. In most conditions, adding gypsum by itself will not loosen compacted or heavy clay soils. WebOct 4, 2016 · Gypsum (calcium sulphate) is sparingly soluble, but the sodium (and magnesium) sulphates that form in the soil solution are very soluble. Rain (or irrigation) is required to leach these soluble... atand 1

WebSep 1, 2015 · Effect of gypsum content on soil permeability. Keren et al. (1980) observed that gypsum only reduces the hydraulic conductivity when it is very fine (<44 μm) and close the macropores of fine textured soils. In soils with coarser textures, by-pass flow is less important and the fine-gypsum infillings have less influence on the saturated ...
