Huang is an assistant professor of soil science at UW–Madison. His research interests include using proximal and remote sensing technology to improve understanding of soil physical processes at various temporal and spatial scales.

This project addresses concerns about nitrate levels in groundwater. Researchers will use novel nano technologies and 3-D printing to manufacture soil sensors. They will then use soil and water samples to evaluate the accuracy of the sensors in the field under different nutrient management practices. The results of this study will support the nutrient management efforts of Wisconsin farmers and the dairy community including university researchers and extension staff. The project aims to help provide more efficient use of Nitrogen fertilizer on-farm and reduction in nutrient losses from intensive agricultural production to groundwater in Wisconsin. Joseph Andrews is collaborating on this research. This project aligns to Dairy Task Force 2.0 recommendation #19 (‘Capital for new and emerging technology’).
