I have a 50:50 Research and Extension appointment. I lead and support state-wide, client-centered programming efforts focused on grassland and hemp production management. I develop educational opportunities and deliver information to forage and livestock producers on profitable management, with specific focus on fescue (the state’s primary forage grass) and on ways to increase grazing days (Graze 300) and thus reduce hay making and feeding costs. I develop new information and demonstrations showing the multiple production, animal welfare, and ecosystem benefits of integrating trees into pastures (silvopasture), and I provide state and national leadership on alternative uses of forage crops (as biofuels) and hemp (as a food, fiber, and medicinal crop).

I work with an interdisciplinary group of crop, livestock, and forest scientists to understand the production implications of silvopasture management. This includes study of tree-forage-livestock interactions and the implications of silvopasture management for animal production and welfare. More traditional forage research programming involves ways to mitigate fescue toxicosis and to increase pasture biodiversity to create more resilient forage systems and provide accompanying environmental benefits.
Industrial hemp studies have largely involved variety and agronomic trials to find plant materials and production management practices that match Virginia's unique regions. Current student efforts are also looking at hemp as a feed resource for horses and livestock.

As Virginia’s State Forage Specialist, I work with agents and producers to improve the productivity, profitability and environmental quality of forage-livestock systems in Virginia, largely through efforts with the Graze 300 program, tall fescue management, and silvopasture systems implementation.
Graze 300 Virginia helps producers achieve 300 days of grazing and documents the benefits. This target is considered the economic optimum across the combination of high and low cattle and feed prices. More information on Graze 300 Virginia can be found here: https://ext.vt.edu/agriculture/graze-300.html
Successful tall fescue management involves mitigating the negative effects of toxic fescue or replacing this forage. Mitigation involves appropriate fertilization and grazing management and incorporating other forages into livestock systems. Replacement involves helping producers switch to better forages.
Silvopastures, the intentional integration of trees and pasture systems, is a new idea for many Virginia producers. Silvopasture systems offer opportunity to increase outputs, diversify production and income streams, and to improve economic and environmental outcomes. More information can be found here: https://ext.vt.edu/agriculture/silvopasture.html
Past efforts with bioenergy production led to an interesting career turn. Many of the issues relevant to bioenergy – e.g., how do industries advance without processors or markets? – are also relevant to industrial hemp. I work with colleagues and industry to help develop and disseminate information on suitable agronomic management practices for feed, fiber and flower hemp production in Virginia.
