56. III. Pedogenic Controls and Regimes A. Factors of Soil Formation B. Podzolization “refers to the removal of iron and/or aluminum from the A horizon downward to the B Horizon” Most common when annual ppt. exceeds 70 cm (27.6 in)

57. III. Pedogenic Controls and Regimes A. Factors of Soil Formation B. Podzolization C. Laterization Intense oxidation Organic accumulation is inhibited Silica is leached from the system

58. III. Pedogenic Controls and Regimes A. Factors of Soil Formation B. Podzolization C. Laterization D. Calcification

61. Soil Catena

62. IV. Factor of Time V. Geomorphic Sig. of Soils e.g.: building foundations hydrologic responses to ppt. permanence of road construction
