REPRESENTATIVE SOIL PROFILE FOR LAKEHURST SAND

O horizon : organic layer with recognizable leaves, twigs, and bark on the surface, and indistinguishable decomposed remains of living organisms underneath

A1 horizon: surface layer; color varies from dark gray to black because organic matter is incorporated into the soil

A2 horizon: subsurface; zone of removal of nutrients, iron, and/or clay by downward moving water to lower depths of profile. Usually lighter colored than the surface layer

B horizons: subsoil; acts like a filter accumulating or catching downward moving components removed from subsurface layer. Usually dark iron colored and may contain clay particles

C horizons: substratum; transition area between soil and parent material; clay layers and mineral particles may be found in this horizon; color is usually lighter than subsoil
