Flue gas desulfurization gypsum (FGDG), a by-product of wet and semi-dry desulfurization processes, has been used as alkali soil amendments in northeastern China. In this research, the continuity of FGDG as alkali soil amendments is confirmed from the point of view of corn production and parameters such as pH, EC and ESP. Moreover, correlation coefficients between various measured values indicate the soil reclamation mechanism. It was found that alkali soil reclamation effects achieved by using wet and semi-dry desulfurization gypsum last at least eight and seven years, respectively.
