Long-term effects of gypsum on the chemistry of sodic soils
Ameliorating sodic soils usually involves displacing exchangeable sodium with calcium by applying gypsum (CaSO₄·2H 2 O). Gypsum reduces clay dispersion and improves the structure of sodic soils ( Rengasamy and Churchman, 1999 ), but there are also concerns about negative effects in the long term. For example, saline water tables …
