  		Fig. 1. Effect of tillage [conventional (CT) and no-tillage (NT)] and residue burning [burn (B) and no burn (NB)] on soil surface CO2 flux over a 2-yr period from two locations (PTBS and CBES) in the Mississippi River delta region of eastern Arkansas. Standard error bars are provided for data means.
