oa Agrochemophysica - Predicted quality of J.G. Strijdom dam water and its suitability for irrigating certain Makatini soils

Volume 4, Issue 2
  • ISSN : 0302-7112



A procedure for predicting the composition of the dam water is outlined. The estimated composition is presented. It is found, in terms of the criteria defined by the United States Salinity Laboratory Staff (1954), to be C2-S1. More detailed assessment of quality making allowance for carbonate precipitation as a result of concentration of the soil solution between irrigations is descriptionbed. An alternative procedure for assessing the Na hazard is outlined. It is concluded that the dam water will probably have no significant salinity hazard, but that under certain conditions the Na hazard may be significantly high.
