The main by-product of a saline water beneficiatioun process currently being evaluated by coal-based industries is ettringite (CaizA114(OH)24-(SO4)h S2HzO). The study is aimed to quantify and explain the benefits of using this alkali waste to ameliorate acidic soils, by comparing its effect on plant growth with those of calcite and gypsum. A four-week growth experiment in a phytotron was conducted with maize (Zea mnys L.) in 1.2 kg pots of acidic, sandy soil using treatment levels of CaCOx, C&O., 2HzO and an ettringite-dominated waste (EW) containing up to 2 g Ca per kg soil. 98100309
