Extension Professor: Agronomy Specialist

Heather Darby is an agronomic and soils specialist for the University of Vermont Extension. She received her MS from the University of Wisconsin in Agronomy and her Ph.D. in Crops and Soils at Oregon State University. Being raised on a dairy farm in Northwestern Vermont has also allowed her to play an active role in all aspects of dairy farming as well as gain knowledge of the land and create an awareness of the hard work and dedication required to operate a farm. These practical experiences complemented by her education have focused her attention towards sustainable agriculture and promotion of environmental stewardship of the land. Heather is involved with implementing many research and outreach programs in the areas of fuel, forage and grain production systems in New England. Outreach programs have focused on delivering on-farm education in the areas of soil health, nutrient management, organic grain and forage production, and oilseed production. Research has focused on traditional and niche crop variety trials, weed management strategies and cropping systems development.
