Major Soil Horizons and Their Characteristics
B C Surface accumulation of partially decayed organic matter Mineral soil in which mixing of surface organic matter and root growth masks effects of chemical leaching Mineral soil in which weathering and leaching dominate horizon characteristics Mineral soil zone affected by chemical deposition of material leached from A horizon Parent material or mineral horizon largely unaffected by soil development Fig. 2.4 p. 21
