ItemDryland salting in Victoria and Western Australia: a literature review( 1982)Soil salination is the accumulation of soluble salts in the root zone in excess of the level able to be tolerated by the vegetation community. There are two processes by which this may occur; irrigation induced soil salinisation, and a group in non-irrigated areas, collectively known as dryland salting. Irrigation salting has been recognised for thousands of years (Jacobsen and Adams, (1958) quoted by Peck, 1978). However no such ancient references are presently known in the case of dryland salting. Dryland salting appears to be a relatively recent phenomenon. In order to review the literature relevant to dryland salting only the major contributions from Western Australia and Victoria are discussed. Dryland salting is known to occur in every Australian state, though as yet discussions of it have not found their way into the scientific literature. The Northern American literature was also omitted as the nature of their problem is different – owing to the geological type. Although their literature would be useful if the review was orientated towards solutions to the problem of dryland salting. The review discussed the changing nature of the literature noting the move from the “qualitative” approach of the early authors (Burvill, 1945; 1950 and Teakle, 1953) to a more recent detailed and “quantitative” one (Peck and Hurle, 1973 and Holmes and Talsma, 1981) . Furthermore it contrasts the amount and type of research completed in Western Australia and Victoria, noting the dominance of the first mentioned state.
