WebMaster Soil Horizons Soil horizons are named using combinations of letters and numbers. Six general kinds of horizons may occur in soil profiles. They are named with the capital letters O, A, E, B, C, and R. These are called master horizons. In Figure 6.1, each master horizon is shown in the relative position in which it occurs in a soil profile. WebE: An E horizon is a zone of strong leaching, or eluviation. The chemistry and hydrology of this horizon are such that constituents such as clay, organic matter, and minerals like iron oxides are removed, leaving behind the un-pigmented soil particles. This represents a loss of soil constituents from the E horizon.
