Chemical Impurities: While the chemical formula for gypsum is relatively simple (CaSO4·2H2O), natural gypsum deposits may contain impurities, including small amounts of other minerals or elements. Gypsum is the most common sodic soil amendment tools due to its high solubility, lower cost, higher availability, and secure handling. Even in non-sodic soils; gypsum improves soil structure by increasing flocculation, aggregate stability, and water infiltration (Malik et al., 1991). Table1: Potential impact of gypsum application on soilWhile in 20–40 and 40–60 cm soil columns, the efficiency was non-gypsum halophytic grass treatments >125% G. This higher response of gypsum on the topsoil layer (0–20 cm) might be due to direct application of gypsum on this layer and the last two soil layers received gypsum indirectly by leaching.Feb 12, 2024 · One of gypsum’s primary functions in soil is its ability to improve soil structure. In many cases, soil can become compacted, limiting root growth and water infiltration. Gypsum works to counteract this compaction by promoting flocculation, a process in which soil particles aggregate into small, crumb-like clusters.

When PG/gypsum are used with lime, cement and FA in stabilized soil, although the gypsum can further improve soil strength, there is an optimal ratio of cement, lime to gypsum when a maximum UCS is obtained for the stabilized soil (Ahmed, 2015; Aldaood et al., 2014, 2015; James and Pandian, 2014).

Gypsum, or calcium sulfate (CaSO4), is a naturally occurring, neutral salt (pH ~6.7).

This can be a great way to provide better soil quality to a wide variety of crops ...A rapid, semiquantitative method (I) and a quantitative method (II) are proposed for the determination of gypsum in soils. Method I involves the determination of the degree of gypsum-unsaturation of an aqueous soil extract nearly saturated with gypsum, i.e., sufficiently dilute to dissolve all gypsum initially present.2. Gypsum Helps Reclaim Sodic Soils. Gypsum is used in the reclamation of sodic soils (Aldrich and Schoonover 1951). Where the exchangeable sodium percentage (ESP) of sodic soils is too high, it must be decreased for soil improvement and better crop growth. The most economical way is to add gypsum which supplies calcium.These gypsum deposits became sedimentary rock beds when they were cemented together.
