How are soil horizons produced and identified
WebSoil horizons are horizontal bands or layers in the soil profile. The main horizons, called master horizons, are O, A, E, B, C and R. Horizons and characteristics. The O horizon is an organic horizon with little mineral material. It can be found in forest soils, when leaves or needles that fall on the ground form a thin organic layer. WebSoil color varies between soil horizons, and therefore soil colors extracted from soil profile images can be used to differentiate horizons (Fig. 1). Other color contrast features, such as redoximorphic features, krotovinas, and rocks, have been identified and their shapes and distribution can be quantified using image analysis methods.
