New Research on Soil CO2 Flux and Photosynthesis Measurement
Presented at ASA Annual Conference

November 2004

LI-COR Biosciences presented new research at the November 2004 meeting of the Agronomy Society of America in Seattle, Washington.

Dr. Dayle McDermitt, LI-COR vice president of science and technology, presented "Analysis of Soil CO2 Efflux Data. Theoretical Considerations and Comparison of Two Measurement Approaches." The presentation focuses on new technology for a more complete method of computing soil CO2 flux in the presence of soil moisture evaporation. The technology takes advantage of continuous diurnal records to develop a more complete understanding of physical and biological processes in the soil system and provides reliable estimates of soil carbon balance.  

This presentation is available in pdf format here.

LI-COR scientists also presented two posters: "Physical Description and Characterization of a Soil CO2 Flux Measurement System  Designed for Survey and Long-term Unattended Measurements," and "Correcting for Changes in Oxygen Concentration in the LI-6400 Portable Photosynthesis System."   Copies of these posters are available as PDF downloads by clicking on the poster title above.

LI-COR expanded its instrument presentation at the ASA meeting to include products from the company’s biotechnology product line.   The Model 4300 DNA Analysis System is used for genomic studies related to plants including AFLP® analysis,Tilling® for reverse genetics and Ecotilling for SNP discovery.

LI-COR Biosciences is a leader in the design and manufacture of instrument systems for plant biology, biotechnology, and environmental research. LI-COR instruments for photosynthesis, carbon dioxide analysis and light measurement are recognized worldwide for standard-setting innovation in plant science research and environmental monitoring. The company pioneered the development of infrared fluorescence labeling and detection systems for proteomic and genomic research.

Founded in 1971, the privately held company is based in Lincoln, Nebraska, with subsidiaries in Germany and the United Kingdom. LI-COR systems are used in more than 100 countries and are supported by a global network of distributors.
