- ... A field-calibrated computer model was used to study the interaction of nitrogen (N) and water management for corn (Zea mays L.) production on sandy soils in the central Platte Valley of Nebraska. Most irrigation in this area is with pumped groundwater which at many locations contains from 10 to 30 ppm (or more) of nitrate nitrogen (NO-3-N). Simulation results were used to estimate the effects of i ...

- ... Paraffin wax is being used as a soil treatment to increase the water runoff yield from precipitation. However, the increasing costs of petroleum products and occasional treatment failures prompted this laboratory study to improve treatment-weathering resistance, decrease wax application rates, and substitute residual waxes for the more expensive paraffin. Ten residual waxes and two paraffin waxes ...
