The chemical response of deep, leached and weathered soils of the Mpumalanga Highveld, South Africa, to irrigation with saline mine water

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...

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. 2014-07-30T17:25:25Z 2014-07-30T17:25:25Z 2000 Master Thesis Masters MSc http://hdl.handle.net/11427/4189 eng application/pdf University of Cape Town Faculty of Science Department of Geological Sciences
