Haplorthod
A soil profile of a well drained, sandy Haplorthod in Michigan. This soil has an ochric epipedon consisting of a dark brown surface
layer (about 10 centimeters thick) and an underlying light gray albic horizon (between depths of 10 and about 30 centimeters).
Note the irregular lower boundary of the albic horizon. Below the albic horizon is a brown and reddish yellow spodic horizon that extends to a depth of about 90 centimetrs. Note the brown streaks extending into the reddish yellow material. The tongues of albic and spodic materials reflect the flow of water through the soil. (Soil Survey Staff. 2015. Illustrated guide to Soil Taxonomy. U.S. Department of Agriculture, Natural Resources Conservation Service, National Soil Survey Center, Lincoln, Nebraska)
Haplorthods are the relatively freely drained Orthods that either have an albic (light-colored and leached) horizon and a spodic (accumulation of translocated organic matter in complex with aluminum and also commonly iron) subsoil 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 (clay accumulation) subsoil horizon or kandic (very low cationexchange capacity) subsoil horizon over relatively unaltered unconsolidated materials or on rock. 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.
