Includes bibliographical references. / Coal mining in the Highveld region of Mpumalanga Province, South Africa generates between 14 and 30 million litres of waste water per day. Much of the water is saline (TDS> 2500 mg/I) and has high concentrations of dissolved SO₄²⁻, Ca²⁺ and Mg²⁺. Crop irrigation has been proposed as a useful way to dispose of saline mine water and enhance agricultural productivity in this low rainfall (˂800 mm/year) region. In order to avoid undesirable salinization of the regional groundwater, it is necessary that soils immobilize, at least partially, the dissolved salt load of irrigation water.
