Fig. 3. Net nitrification (upper figures) and CO₂ evolution (lower figures) as averaged for each combination of soil and matric potential. Bars represent standard error. The values below the CO₂ data points for the L3 and L5 soils indicate the numeric matric potentials assigned to the average results shown in the figure. For the L1 soil, the order of succession of data points along the water content axis was as expected from the matric potentials.
