  • Plot-Scale Field Investigation : Characterizing Water Motion in Sandy Agricultural Soils

    Creator:
    Nolasco, Stephanie M.
    Abstract:
    Irrigated agricultural production in sandy soils presents several unique challenges to growers, including naturally high permeability, low native water retention, as well as high rates of water drainage losses and leaching of chemicals to the shallow aquifers. This study is an initial investigation into water motion in the sandy agricultural...
