Improving irrigation water use efficiency in vegetable and crop production is a high priority for agricultural producers as they face challenges of climate change and more frequent droughts. We are currently testing various approaches to irrigation scheduling, including sensor technologies, to improve water use efficiency. We have also measured irrigation withdrawals on multiple farms through the growing season and modeled water use efficiency using a water balance approach, comparing different crops and growing environments. Working with ¶¶Òõ̽̽ Extension, researchers are also identifying appropriate soil moisture monitoring technology for farms in the Northeast.

Water quality degradation from agricultural field runoff that contains excess nutrients is a pressing environmental challenge in Vermont and throughout the world. CEE researchers and collaborators study multiple treatment technologies employed at both the farmstead/production and edge of field areas. Working with ¶¶Òõ̽̽ Extension and many other partners, we are designing and testing of novel denitrifying bioreactors, evaluating effect of best management practices (BMPs) on surface and subsurface water and nutrient fluxes, designing and testing phosphorus removal technologies, monitoring and modeling watershed hydrology and nutrient export from agricultural watersheds in the Lake Champlain Basin, and studying the effects of climate change on agricultural fields.
