Cambic Horizon -

The presence of an argillic horizon is a primary diagnostic criterion for several soil orders in the USDA Soil Taxonomy, most notably:

The argillic horizon forms through a process called . As water percolates through the upper soil layers (eluviation), it strips out fine clay particles and transports them downward. These clays then accumulate in the subsurface, creating a layer with a significantly higher clay content than the horizons above or below it. 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 presence of an argillic horizon is a
