Soil profile Heidepodsol with Ortstein in the Lüneburg Heath

The term Ortstein describes a soil horizon in the subsoil of Podzol . The elimination of the humus and iron compounds washed out in the Ae horizon of the topsoil creates a cemented, sandy, solid illuvial horizon . Ortstein consists of a brown-black Bh horizon with predominantly humus accumulation and a rust-brown BS horizon underneath with accumulation of sesquioxides , which together are only 10 to 20 cm thick and have noticeable speckles. Since Ortstein is almost impermeable to water and the roots can hardly penetrate it, the vegetation is severely impaired.

The stone layer can be broken up by deep plowing and the land can be made arable .
