In this study, EM-38 soil salinity surveys were conducted at the SJRIP (San Joaquin River Improvement Project) facility managed by the Panoche Water District (Los Banos, California) where subsurface drainage water is re-used on forages such as ‘Jose’ tall wheatgrass and alfalfa to reduce drainage discharge and salt loading into the San Joaquin River.
The objective was to optimize the sustainability of this reuse facility. This was achieved by assessing the spatial and temporal distribution of the root zone salinity in selected fields of ‘Jose’ tall wheatgrass and alfalfa in the drainage reuse facility, some of which have been irrigated with brackish subsurface drainage water for over fifteen years.
