Abstract

The impact of two specific practices such as, reduced tillage and cover cropping were proposed for increasing soil Carbon in corn/soybean rotations. Two fields of 17 ha and 37 ha in size were used for the project. NEE, latent heat flux, sensible heat flux were measured in both fields throughout the two year period by eddy covariance, using CSAT sonic anemometers and LI-7500 open-path infrared gas analyzers. The NEE measurements during and immediately following fall tillage showed little difference between the two treatments. The cummulative difference between the two fields during the post-tillage, pre-freezing period was approximately 0.1 Mg Ha -1.
