Haplorthod PL
A Typic Haplorthod from south-west Poland--lower Silesia region and the Sudetes Mountains. These soils formed in materials weathered from Upper Cretaceous sandstone. (Photo provided by Cezary Kabala, Institute of Soil Science, University of Environmental and Life Sciences, Wroclaw, Poland.)
In the US, Typic Haplorthods occur mostly in the northeastern and northwestern parts of the United States as well as Michigan, Wisconsin, Minnesota, West Virginia, and Maryland. They generally support forest vegetation, but some have been cleared for pasture or crop production. The most common crops are small grain, corn for silage, and in Maine potatoes.
These are the relatively freely drained Spodosols that either have an albic horizon and a spodic horizon or, under cultivation, commonly have only a spodic horizon below an Ap horizon. The spodic horizon may rest on a lower sequum with an argillic or kandic horizon, on relatively unaltered unconsolidated materials, or on rock. The soil temperature regime is frigid or warmer, and the moisture regime is predominantly udic. Most Haplorthods have, or used to have, forest vegetation, mainly conifers but also hardwoods in some areas. A majority of these soils formed in sandy deposits or in materials weathered from sandstone or quartzite.
These soils are classified as Albic Podzols (Arenic, Endoskeletic) by the World Reference Base (WRB).
