Abstract

Manganese extractable by sodium hydrosulfite was determined for 9 soil profiles of a bio-topo (vegetation and drainage) sequence in southeastern Iowa. The distribution of manganese in the soils studied is influenced by vegetation, drainage, and pH. Under prairie vegetation the manganese is evenly distributed with depth in the well-drained soil, but with increasing wetness of the soil profile, manganese is apparently lost from the A1 horizon and accumulates in the lower part of the B horizon. Manganese accumulates in the A1 and A2 horizons of the well-drained soils developed under forest vegetation, but in profiles of increasing wetness the amount of manganese in the A1 and A2 horizons decreases and the amount of manganese in the lower B horizon increases. The distribution of manganese in the transition prairie forest soils was intermediate between soils developed under prairie vegetation and those developed under forest vegetation.
