Abstract

The contribution to net ecosystem productivity (NEP) of respiration from the soil, measured with a CO 2 profile system located in a corn canopy was examined. CO 2 profiles were monitored in a no-till corn canopy, at the AmeriFlux tower located near Champaign, IIinois. The CO 2 profile and AmeriFlux data were used to compute fluxes of CO 2 in the canopy. The profile measurements showed an accumulation of CO 2 in the corn canopy during night hours. It was found that CO 2 were greatest at night at the three levels where measurements were made and began to decrease at sunrise.
