Low intensity processes, such as movement of soluble salts or oxidazation and reduction of iron may occur. There are no dominant processes in the C horizon; minimal additions and losses of highly soluble material (e.g., salts) may occur.compacted by the glacier. It’s also called “hardpan” and invariably frustrates local gardeners when they try to dig. What’s an aquifer?
