Carbon Sequestration Pilot Studies and the LI-8100

Read how Richard Esposito of Southern Company (Atlanta, GA), along with other members of the Southeast Regional Carbon Sequestration Partnership (SECARB), are using the LI-8100 Automated Soil CO2 Flux System to perform baseline CO2 flux monitoring to establish natural rates of CO2 flux at test sites in Alabama and Mississippi.

Measuring Soil CO2 Flux in Maize & Soybean Agroecosystems

Learn how researchers at the University of Nebraska-Lincoln are using the LI-8100 Automated Soil CO2 Flux System to study the carbon cycle of three maize-based agroecosystems: irrigated continuous maze, irrigated maize-soybean rotation, and rainfed maize-soybean rotation, all standard cropping systems in the central U.S.
