CH4, CO2 Fluxes via Static Chambers — Resource Gradient Experiment
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Methane and carbon dioxide fluxes, plus soil inorganic nitrogen concentrations, from plots of continuous corn in the Resource Gradient Experiment.
This datatable is part of the Methane consumption as influenced by nitrogen fertilization and tillage dataset.
This dataset contains data from Pongthep Suwanwaree’s dissertation entitled: Methane Oxidation in Terrestrial Ecosystem’s: Patterns and Effects of Disturbance, submitted to Michigan State University, Department of Crop and Soil Science, 2003.
