Abstract Not Available – First paragraph follows:
Leaching of soluble salts—necessary for sustained irrigated agriculture—is accomplished by allowing some surface applied water to pass completely through the crop root zone. Although leaching is often carried out to a limited degree with each application of irrigation water, it is sometimes only possible to leach annually or less frequently, depending upon the crop grown, water supply and other local conditions.
