Project Overview

We propose to use the eddy covariance (EC) method as our primary tool (see Chen et al. 2008) in making intensive, continuous measurements of NEP, water loss through evapotranspiration (ET) and energy balance at the six KBS-GLBRC “Scale-Up Fields”: switchgrass, restored prairie and continuous corn fields (two replicates of each system). A combination of dynamic chambers and microclimatic and biometric measurements will also be used to collect various needed data on soil C, resource use (water, light and N), carbon gain (photosynthesis) and loss (respiration) and changes in major biophysical variables as well as heat energy to achieve our study objectives.

We hypothesize that significant differences exist in ecosystem production, biophysical regulations and belowground carbon allocation among the three biofuel production systems. These differences are clearly reflected at multiple temporal scales.

The data and results produced from this study will be posted on an open Webpage in order to best promote their uses (e.g., modeling research of the Thrust 4 toward the missions of the DOE-BRC.

Objective 1:
Examine the magnitudes and dynamics of net ecosystem production (NEP) and soil C at the six “Scale-Up Fields” that have been identified at the Kellogg Biological Station (KBS).

Objective 2:
Investigate the biophysical regulations and resource use limitations for maximizing NEP and soil C at these sites.

Conceptual Framework and Hypothesis

We hypothesize that significant differences exist in ecosystem production, biophysical regulations and belowground carbon allocation among the three biofuel production systems. These differences are clearly reflected at multiple temporal scales.
