If an alluvial forest soil were flooded for 10 days, and you sampled the gases evolving from the wet soil, what gases would you expect to find (other than oxygen and carbon dioxide)? In what order of appearance? Explain.

If you were in the field trying to delineate the socalled drier end of a wetland area, what are three soil properties and three other indicators that you might look for?
