Bulls, New Zealand, FACE Yield Data

FACE stands for Free Air CO2 Enrichment. FACE technology is capable of providing a means by which the environment around growing plants may be modified to realistically simulate future concentrations of atmospheric carbon dioxide (CO2). Unlike growth chambers and greenhouses, no containment is required with FACE designs. Previously difficult-to-study natural conditions such as temperature, precipitation, pollination, wind, humidity, and sunlight are now possible. In addition, there are, in theory, no plant size or growth problems caused by the constraint of enclosures (although the system must be sized, or expandable, to accommodate the anticipated future size of the plants during the lifetime of the experiment). Therefore, long-term studies may be conducted. FACE field data represent plant and ecosystem responses to concentrations of atmospheric CO2 in a natural setting possible during the next century.
