I'm not sure where to post my question, however, could someone please explain the difference between the soil formation processes of addition and translocation? For example, in a Bf horizon, would the dominant soil formation process be the addition of Fe and Al oxides or the translocation of these oxides from the above A horizons. I am also unsure about a horizon like Bt, which is anaerobic, does this mean the loss of macropores, of the addition of water, via flooding? Thanks :)
