Follett and agricultural engineer Allen R. Dedrick—have been named to the Agricultural Research Service (ARS) Science Hall of Fame for their work on irrigation management, identifying key parasites infecting the water and food supply, and sustainable agricultural production during global climate change. The ARS Science Hall of Fame was established in 1986 to recognize agency researchers for lifelong achievements in agricultural sciences and technology.

ARS scientists Kurt Spokas and John Baker found that amending glacial soils with biochar made from macadamia nut shells reduced a range of greenhouse gas emissions. Studies by the USDA’s Agricultural Research Service (ARS) are beginning to yield valuable information about how biochar—a charred biomass created from wood, plant material and manure—is able to interact beneficially with soil and crops.
