   What does Orstein mean in soil taxonomy?

   • Orstein is defined in Soil Taxonomy as being at least 25 mm thick and being cemented in at least 50 percent of its volume (thus root restrictive). It is a diagnostic soil characteristic used to define a family rupture-resistance class recognized for some Spodosols.

   What is a diagnostic horizon in soil taxonomy?

   • In Soil Taxonomy, diagnostic horizons are used to classify soils. They may contain distinctive features that set them apart from adjacent layers. Diagnostic horizons differ from genetic horizons, such as a Bt1 horizon, in that they are defined by their specific diagnostic properties. Genetic horizons, on the other hand, are layers in the soil that differ from adjacent layers in some observable property as a result of pedogenic processes.

   What is soil classification?

   • A common application of soil classification (the act of identifying the taxonomic classification for a given soil) is to develop models of how soils of different classifications associate with one another within a landscape, which can eventually be used in soil mapping.

   What is the purpose of soil taxonomy?

   • A major purpose of Soil Taxonomy is to group soils that exhibit similar morphology. See horizon nomenclature and micromorphology. Soil profile.—A more or less two-dimensional vertical cut through the soil on a plane at right angles to the soil surface. It is an exposure used for describing the kinds and arrangement of horizons making up the soil.

   How do I learn soil taxonomy?

   • Become familiar with the 12 soil orders. Understand the structure of Soil Taxonomy. Become familiar with the contents of a county soil survey report. Use a soil survey report for land use evaluation. The word, “taxonomy” is based on the Greek words “taxis”, meaning arrangement; and “nomia”, meaning method.

   How do you determine the Order of a soil?

   • To determine the soil order, begin at the top of the key and arrange the following soils from highest to most least weathered: Oxisols, Alfisols, Mollisols, Entisols, and Inceptisols. Soil with a spodic horizon at 30 cm depth and permafrost at 80 cm depth falls under the Entisol order. This soil has not yet developed the diagnostic horizons that define the other soil orders.
