Switchgrass Forage 
Experts with UT's Institute of Agriculture believe switchgrass is nutritious for farm animals, and environmentally friendly.

(3 mentions)

A recent report says the U.S. could produce a billion tons of biofuel materials each year, without impacting food supplies. We are working on ways to produce biomass and alternative fuels.

Forage Research 
UT researchers are looking for the best forage for cattle to produce high quality beef. The goal is to grow hay for cattle in the hot, dry months of summer when fields are usually barren.

Food vs. Fuel 
UT Ag Researchers are studying what could be a compromise between food and fuel.

Biofuel Refinery Groundbreaking 
Many believe America must find new ways to create energy and fuel. UT recently started construction on a biorefinery to research the manufacture of biofuels from agricultural products.
