Annual teaching with heavy water applications by ponding, with the aid of plastic levees, or use of sprinklers, may be the answer to problems of excess salt accumulation in Coachella Valley vineyards. Trials in a Thompson Seedless vineyard showed marked improvement in vine condition following these special teaching practices. Previous installations of additional tile drains had not corrected this vineyard salinity problem. Salt accumulation in the soil, with resulting vine decline, is the most important current problem facing grape growers in the Coachella Valley.
