Effect of byproducts of flue gas desulfurization on the soluble salts composition and chemical properties of sodic soils.

The byproducts of flue gas desulfurization (BFGD) are a useful external source of Ca(2+) for the reclamation of sodic soils because they are comparatively cheap, generally available and have high gypsum content. The ion solution composition of sodic soils also plays an important role in the reclamat...
