A global journey into making our lives better... O horizon: 100% organic (leaf litter, etc.)

A horizon: organic rich (~5-10%), depleted in fines and soluble ions coarse, crumbly texture (lacking clay), dark color (organic carbon)

B horizon: organic poor, enriched in fines and soluble ions compact, dense texture, light in color (little organic carbon, clays are tan/gray color)

C horizon: physically and chemically weathered parent material

Hardpans are generally located at the top part of the B horizon.]]> O horizon: 100% organic (leaf litter, etc.)
