Abstract
SUMMARY Dryland salinity is a widespread and serious environmental problem in western Victoria. As a result river environs and farmland have been seriously degraded with loss of habitat, reduced farm production and increased erosion. Until recently, the preferred method of salinity investigation was centred around expensive drilling programs to obtain information on groundwater provinces. More recently, electromagnetic surveys have provided the means of rapidly assessing the levels of soil and water salinities present within the landscape. At a site south of Glenthompson, Victoria, the results of an electromagnetic survey together with an investigation of relevant soil properties are being used to plan salinity control options. High recharge areas do not appear to be present in the study district. The effects of agronomic control options, such as the establishment of perennial grasses, can be predicted by the use of a monthly water balance whereby climatic factors and the crop's efficiency in plant water ...
