Professional Biography

Dr. Chad Lee is an Extension Professor for Corn Agronomy and Bourbon Grains at the University of Kentucky. Dr. Lee provides statewide leadership in Extension activities related to agronomic management of corn, primarily, and the small grains used in Bourbon distilling. Dr. Lee leads an applied research program in corn, wheat, rye, barley with an emphasis on high-yielding, high-quality grain production in no-tillage and reduced tillage systems. Dr. Lee investigates cover crops, crop rotations and other practices that allow farmers to produce excellent crops and improve their farms over time. 

Dr. Lee works closely with the Kentucky Corn Growers and helps plan and teach segments of the Kentucky C.O.R.E. program operated by the Kentucky Corn Growers. Dr. Lee serves on committees with Kentucky Farm Bureau. Dr. Lee teaches a section on Bourbon grains production to the James B. Beam Institute apprentices.
