​​Camp HandCamp Hand is an assistant professor and Extension cotton specialist at the University of Georgia in Tifton. His research and Extension programs focus on cotton agronomics in Georgia, and his goal is to work with the UGA county agents and growers to answer questions that will help Georgia growers remain sustainable and economical. Camp received his BS and MS degrees at Auburn University in horticulture while minoring in agronomy. His graduate work at Auburn was conducted under Dr. Wheeler Foshee. He then went on to pursue a PhD at the University of Georgia in Tifton in weed science under the direction of Dr. Stanley Culpepper.

Brian Pieralisi Brian Pieralisi is currently the Extension cotton agronomist at Mississippi State University. He was previously employed at the Delta Research and Extension Center in Stoneville, Mississippi, as a research associate under Dr. Bobby Golden while pursuing a PhD in soybean nutrient uptake. Brian has experience with both soil fertility and weed science research in cotton, corn, soybean, and rice. He served as a fourth-generation cotton, corn, and soybean producer in the Mississippi Delta for 15 years before earning a PhD at Mississippi State. Brian also earned an MBA from Delta State University while operating a 4,500-acre farm in 2005.

Randy Norton ​​Randy Norton is an associate regional Extension specialist with the University of Arizona and also serves as the resident director of the Safford Agricultural Center. He has a BS degree in plant sciences with an emphasis in crop science and MS and PhD degrees in soil and water science with an emphasis in soil fertility and soil chemistry. The primary focus of his work is improving the efficiency and sustainability of desert agricultural systems through a broad research and Extension program directed at solving production chal​lenges faced by growers across Arizona. Areas of research and Extension focus include soil fertility, variety evaluation, and management of certain pests and diseases in Arizona crop production systems.
