Cambic Horizon Link Link

The layer must exhibit higher chroma, redder hue, or lower value than the underlying unaltered C horizon. This shift represents the oxidation of iron minerals (brownification).

To be classified as a cambic horizon under major systems like the USDA Soil Taxonomy and the World Reference Base for Soil Resources (WRB) , the layer must satisfy precise morphological and chemical parameters: cambic horizon

An is a subsurface diagnostic soil horizon characterized by the accumulation of silicate clays. It is a key concept in soil classification systems like USDA Soil Taxonomy and the WRB (World Reference Base for Soil Resources). The layer must exhibit higher chroma, redder hue,

The development of a cambic horizon relies on internal material transformation rather than long-distance movement down the soil profile. The primary formation processes include: The layer must exhibit higher chroma
