Book excerpt: Excerpt from The Agroforestry Demonstration Program in the San Joaquin Valley: Progress Report; March 1988 Irrigation of farmland creates the need to leach accumulated salts from the soil in order to allow the continued production of crops. Problems in the San Joaquin Valley involve shallow ground water tables created when saline water accumulates above low permeable clay layers in the soil. These high water tables must be lowered below crop root zones in order to prevent losses in production. Additional problems involve potentially harmful elements, such as selenium and boron, which may be contained in this saline water. The Agroforestry Demonstration Program currently underway is testing and evaluating the feasibility of utilizing trees to reduce the amount of agricultural drainage water generated within the San Joaquin Valley. Salt-tolerant trees have the potential to lower the water table and reduce the volume of this drainage water through evapotranspiration and consumptive uses. Agro forestry can therefore lower the costs of drainage water manage ment by reducing the amount of water which must be treated and/or disposed of in evaporation ponds, solar ponds, or deep-injection wells. Figure 1 illustrates the potential of the agroforestry system to reduce both the volume of drainage water and the volume of irrigation water used on farms in the San Joaquin Valley.
