The overall goal of my program is to extend research-based information to producers to help them improve crop productivity and product quality while minimizing their economic risks and reducing environmental impacts. I assist them in diagnosing field production problems, and I conduct research to identify and/or improve upon effective and economical solutions to their problems. I help them understand and comply with new regulations, and I have developed research projects to address the efficient, reduced-risk use of water, fertilizers and pesticides.
