- ... Soil nitrogen dynamics is affected by the interaction of cover crops and rainfall amount and distribution in rainfed agricultural production systems. There is a lack of understanding on soil nitrogen losses from cover crop-based based cropping systems receiving different rainfall amounts. A simulation model, RZWQM2 (Root Zone Water Quality Model), was calibrated and validated with field measuremen ...

- ... The need to control glyphosate [N-(phosphonomethyl)glycine]-resistant weed biotypes with tillage and preemergence herbicides in glyphosate-resistant crops (GRCs) is causing a reduction in no-tillage hectarage thereby threatening the advances made in water quality over the past decade. Consequently, if environmental gains afforded by GRCs are to be maintained, then an in-field best management pract ...

- ... Sediment and its associated pollutants entering a water body can be very destructive to the health of that system. Best Management Practices (BMPs) can be used to reduce these pollutants, but understanding the most effective practices is very difficult. Watershed models are the most cost-effective tools to aid in the decision-making process of selecting the BMP that is most effective in reducing t ...
