Abstract:
The dissolution rate of gypsum fragments in aqueous solutions was studied for Ca-soil-gypsum mixtures at two gypsum contents and four soil water velocities. Equations were derived to estimate the dissolution rate coefficient of gypsum fragments at different soil water velocities for a given surface area of gypsum. The effect of contact time on gypsum dissolution rate is much greater at the higher soil water velocity range than at the lower range. The soil water velocity also has a significant effect on sodic soil reclamation. The slower the soil water velocity, the higher the efficiency of replacing Na+ by Ca2+. -from Authors
