Hardpan
Definition
A hard, impermeable, and cemented soil horizon, formed by the accumulation and precipitation of iron, manganese oxides, and silica or humus in the lower layers of podzols. This compact geological layer prevents deep root penetration of plants and normal water infiltration, often causing surface waterlogging.
