Which outcome results from slow rates of oxidation during pedogenesis?

💡 Explanation

The accumulation of ferrous iron occurs because redox reactions slow during pedogenesis due to limited free oxygen during weathering; this causes a reducing rather than oxidizing environment therefore increased ferrous iron levels, rather than iron oxidation reactions.
