Management Practices for Phosphorus and Sediment Reduction in the Salton Sea Watershed

Khaled M. Bali and Isabel Escabosa
Abstract—Nutrients, sediment and silt in drainage waters have been identified as the leading cause for water quality impairments in rivers and waterbodies in California. Approximately one-third of applied irrigation water leaves irrigated field as surface runoff and subsurface drainage.
In this project, we implemented seven standard and improved irrigation and fertigation management practices on a commercial alfalfa field to reduce the load and concentration of phosphorus and sediment in drainage waters. Reducing the amount of surface runoff after the application of P fertilizer is a key factor in reducing the load of P in drainage waters. The loads of P in runoff waters were reduced by as much as 75% compared to normal irrigation and fertigation practices. Water-run application of P increased the concentration and load of P in runoff water by almost 100% compare to broadcast P applications. Avoiding water-run applications can reduce the load of P in runoff water by more than 50%.

Index Terms—Irrigation management, phosphorus, sediments, water quality.
