Fig. 4 Average daily relative saturation S () and redox potential (•) profiles for selected pedons on Days 193, 194, 196, and 204. Dotted S and redox lines are for Pedon 2*. Dashed lines indicate standing water level in the soil pits. Redox and measurements were taken after the soil pits were pumped free of standing water. Redox potentials are averages of three measurements
