270 Improving Accuracy and Precision of Soil Carbon and Greenhouse Gas Emission Measurements and Quantification Oral

Oral Session
ASA Section: Environmental Quality
Soil carbon measurments and greenhouse gas emissions measurements are influenced by Spatial and temporal computation challenges.  To improve the accuracy and pension of these measurements, the methodological strategies, modeling, and statistical approaches are needed to be improved.   In specific, Field sampling schemes, chamber design, approaches for addressing messy and missing data points, and improving flux calculations. This session addresses a wide range of approaches that will help to improve the accuracy and precision of soil carbon and greenhouse gas measurement and quantification.
