Interpretive Summary: The disposal of agricultural drainage waters into surface waters or onto lands leads to salinization and degraded soil and water quality. In some instances the impacts of agricultural drainage disposal may be reduced if drainage waters are isolated and reused for irrigation. Scientific and economic questions remain about the suitability of different waters, soils, and crops for reuse operations; optimal management practices are not yet known. This paper reports results from recent studies in which forage crops were grown in volumetric lysimeters using synthetic saline-sodic drainage waters. The data are evaluated against a simulation model that could potentially assist in the design and management of agricultural drainage reuse systems. The results will be of interest to scientists, engineers, and growers working on the development of sustainable drainage management practices.
