Joshua Faulkner

I coordinate  the Farming and Climate Change Program in the UVM Extension Center for Sustainable Agriculture.  I do applied research and outreach on soil, water, and nutrient related issues across the state and provide technical assistance to farmers on practices and innovative solutions to improve the management of these resources.  My work spans the farmstead to the watershed in scale.
