Retrospective Theses and Dissertations

A study was conducted to evaluate the effects of sodium chloride (NaCl) and calcium chloride (CaCl[subscript]2) at different concentrations in the soil profile on saturated hydraulic conductivity, salt movement, and transport of nitrate-nitrogen (NO[subscript]3-N) and atrazine to the groundwater. Also, the effects of various water table depths were evaluated on salt movement and the fate of NO[subscript]3-N under simultaneous irrigation and drainage practices;Two sets of experiments were conducted in the laboratory under simulated saline and waterlogged conditions. Three sets of soil columns (45, 75, and 115-cm long) were fabricated using PVC pipes of ...
