Implication of Gypsum Rates to Optimize Hydraulic Conductivity for Variable‐Texture Saline–Sodic Soils Reclamation

Sodium (Na⁺) dominated soils reduce saturated hydraulic conductivity (Kₛ) by clay dispersion and plugging pores, while gypsum (CaSO₄•2H₂O) application counters these properties. However, variable retrieval of texturally different saline–sodic soils with gypsum at soil gypsum requirement (SGR) devise...
