WebEarth Sciences questions and answers. The table given here shows partial pressures of O2 and N2O in the pore space of an Alfisol under deciduous forest cover as a function of depth in the soil profile. Calculate the N2O/O2 molar ratio in soil air and in the soil solution as a function of depth, then plot the two ratios on the same graph. Alfisols are a soil order in USDA soil taxonomy. Alfisols form in semi-arid to humid areas, typically under a hardwood forest cover. They have a clay-enriched subsoil and relatively high native fertility.
