In this photo released from the University of Florida’s Institute of Food and Agricultural Sciences, soil and water science graduate student Elena Azuaje uses an auger to collect soil samples in the Osceola National Forest — Wednesday, Feb. 25, 2009. Azuaje was part of a team collecting soil samples for researchers to analyze as part of the state’s largest-ever soil-carbon study. When completed next year, the study could help Floridians venture into the carbon-credit market, a way for governments, farmers and landowners to earn money while helping reduce harmful greenhouse gases by storing carbon in soils.
