With irrigation projects that import water, farmers have transformed millions of acres of land into highly productive fields and orchards. But the dry climate that provides an almost year-round farming season can hasten salt build up in soils. The build-up of salts in poorly drained soils can decrease crop productivity, and there are links between drainage water from irrigated fields and harmful impacts on fish and wildlife.

The 20-page Layperson’s Guide to Agricultural Drainage explores these and other issues associated with agricultural drainage. It includes a drainage primer; regional assessments of the Imperial Valley, San Joaquin Valley and Tulare Lake Basin; and efforts to find new solutions to the old problem of disposal of agricultural drainage water.
