Our mission is to determine and interpret agroecosystem responses to atmospheric and soil processes induced by global change.

Our overall goals are to:

• Reduce uncertainty regarding the effects of rising atmospheric CO₂ concentration on crops, pastures, invasive weeds, and plant diseases.
  
  
• Determine the role of agronomic management practices in the production of CO₂ and other greenhouse gases, as well as the sequestration of atmospheric CO₂ as organic C in soils.

This program addresses the carbon issue at several scales, from controlled laboratory environments to outdoor field exposures to elevated CO₂.

The earth's atmospheric CO₂ concentration has
increased 30% in two centuries. The effects
of this increase remain largely unknown.
