Farmlands OF southwestern Fresno County are in great need of ground water recharge. Most irrigation pumping occurs from below a confining layer of diatomaceous clay, 500 to 700 feet below the ground surface. However, a shallow water table is perched on layers of heavy-textured sedimental soils occurring 75 to 100 feet below all the experimental locations. This zone of water is not pumped for irrigation purposes at present because of high salinity.
