The soil taxonomy is composed of six levels and is designed to classify any soil in the world. • The highest level is soil orders (similar to kingdoms in the Linnaeus system of classifying organisms). • Each order is based on one important diagnostic feature with the key ...
soil that was caked and dried into blocks. These included earthen homes cut into hillsides, homes where mud was “plastered” onto the walls, and adobe homes. Since soil is everywhere, all structures are also built on soil. Selection of sites with the best soil is an important engi-neering decision in the building process.

Soil scientists working in environmental, natural resource, or agronomic management companies Anyone required by the state to be certified as a CPSS or Certified Professional Soil Classifier (CPSC) when doing soil science work for land use evaluation (e.g., septic systems or agricultural management plans).
O horizons – Organic soil materials (other than Lim-nic materials). Any mineral content is commonly a small percentage by volume and < 80% by weight. A horizons – Mineral soil formed at the surface or be-low an O horizon, that exhibits little or no remnant rock structure, and one or more of: i) an accumulation of humified organic matter in -

Soil degradation is a human-induced or natural process which impairs the capacity of soil to function. As an example, in 3000 BC, the Sumerians built large cities in the deserts of Southern Mesopotamia. ...

Exam Information | Soil Science Society of America
Experts in soil science review each of the exam questions and evaluate them according to how successful a minimally competent candidate would be in answering each question. This process statistically maintains a passing score from year to year that is independent of each candidate's level of expertise.

[soil taxonomy] A surface horizon of mineral soil that is dark colored and relatively thick, contains at least 5.8 g kg-1 organic carbon, is not massive and hard or very hard when dry, has a base saturation of>50% when measured at pH 7, has <110 mg P kg-1 soluble in 0.05 M citric acid, and is dominantly saturated with divalent cations (USDA, 1999).
