Reduction of Sulfate Swell in Expansive Clay Subgrades in ...conductivity was then related to sulfate content in soils. Expansion tests were performed to determine the amount of expansion that occurs when lime is added to soils with different sulfate contents. A model that relates the amount of expansion of clay soils to electrical conductivity was proposed.
How to Use Gypsum on Clay Soil | Garden GuidesGypsum is a powdered soil amendment that landscaping experts frequently recommend for loosening hardpan clay soils. Gypsum is a form of hydrated calcium sulfate. In clay soil, gypsum helps to hold clay particles together in clumps, which improves soil structure. Compared to soil conditioners such as limestone, gypsum ...
Improving Clay Soils - FineGardeningSoil texture—The textural designation of a soil is determined by its relative portions of sand, silt, and clay particles, and indicates which of the three most influence the soil's properties.Sand, silt, and clay soil properties are obviously dominated by those respective fractions. For example, clay soils (generally more than 40 percent clay) are often poorly drained.
METHODS FOR SULFATE QUANTIFICATION IN SOILS | .Acid dissolution solublizes most sulfate components in soil and therefore yields the maximum possible sulfate level in soil. This method is an overestimation of the sulfate problem as the pH in lime-treated soils is high (alkaline) and some of the sulfate species mentioned above may not be .
