    A Podzol is a soil formed in a humid climate. The high precipitation flushes carbonates from the soil profile quickly, decreasing the soil pH. Following this, one o r two processes happens

    1.) The iron in the first horizon of the soil profile leaches and is deposited lower down in the soil profile creating an iron rich layer.

    2.) Humic acids move under deposited lord out of the soil profile

    Depending on what substance moves, the classification of the soil changes slightly both are Podzol

      Neat. So is the podzol the combination of (in situation 1) the leached soil and the iron layer? Or does the iron layer become its own “thing”?

        It’s a combo.

        This Ferro-Humic Podzol has both a humic acid and iron enriched horizon (Bfh) and a horizon where the iron continued on and deposited lower (Bf). All of this came from the Ae horizon right under the forest floor (LFH) and the forest floor itself
