Fragipan horizons in soils on moraines near Garpenberg, Sweden exhibit platy structure, brittleness, numerous 0.1 mm diameter discontinuous pores and segregation of sand, silt and clay in former root channels. The underlying parent material lacks these characteristics. Infilling of root channels by segregation products shows that pedogenic processes are active at the present time within the fragipan horizons.
