Gund Fellow, Professor, UVM Extension

Heather Darby is an Agronomic and Soils Specialist for the University of Vermont Extension. Being raised on a dairy farm in Northwest Vermont has allowed her to play an active role in all aspects of dairy farming and gain knowledge of the land; creating an awareness for 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. Heather is involved with research and outreach programs in the areas of fuel, forage, and grain production systems in New England.
