More than 50 scientists participated in the Free-air CO2 enrichment (FACE) experiments at Maricopa, Arizona 1992-1997. The study collected data on plant, soil, and microclimatic responses to the elevated CO2 and its interactions with the water and N treatments. The data are now publically available.

 Guayule is a native scrub that is a natural source of rubber.  Research at the Center is focused on improving this crop of heat and drought tolerance and for latex yield and quality.
 Cotton is a major crop in the southwestern USA. Research is focused on breeding for increased tolerance to heat and drought.
 High throughput phenotyping is being used to accelerate crop improvement. This high clearance tractor is fitted with sensors that allow rapid measurement of multiple parameters such as plant temperature, plant height, and spectral characteristics.
