Agricultural systems are sources and sinks for carbon and to quantify the net effect of these systems on atmospheric CO2 concentration, the amounts of carbon fixed in primary production and that respired by the soil must be known. The objectives of o

To quantify the net effect of agricultural systems on CO2 emissions to the atmosphere, the amount of carbon fixed (primary production) and emitted (soil respiration) under different agronomic management must be estimated. A dynamic chamber system was
