Hyperarid Soils and the Soil Taxonomy
Soil Science Society of America Journal, 2014In the past decade, pedological research in hyperarid environments worldwide has revealed landscapes and soil features that are regionally prevalent and distinctive, but not well captured in the current soil taxonomy. Hyperarid soils bear genetic features that can differ considerably from those in more humid desert environments. In

Soil-forming factors and Soil Taxonomy
Geoderma, 2014Here we analyze the past and present roles of the five soil-forming factors in USDA Soil Taxonomy. As opposed to the 7th Approximation of 1960, the factorial and genetic approach is clearly present in Soil Taxonomy. Soil climate is the most important factor in Soil Taxonomy. It is used at the highest level to define two of the 12 soil orders: Aridisols,

Outlook on Agriculture, 1987
The growth of crops depends on many factors, not least the nature of the soil. It is, therefore, important to be able to describe soils in unequivocal terms, much as living organisms are precisely defined according to the binomial taxonomic system originated by Linnaeus.

Fundamental Changes in Soil Taxonomy
Soil Science Society of America Journal, 2015Soil Taxonomy has become increasingly complex during the past 50 yr, and the number of taxa has grown almost exponentially. This complexity detracts from the ability of Soil Taxonomy to serve the needs of increasingly diverse users. We review the objectives of Soil Taxonomy, discuss current issues with applying Soil Taxonomy, and present some suggested

Soil Horizons, 2012
The Romanian System of Soil Taxonomy (RSST) is a consistent soil classification based on the concept of soil as a natural self‐standing entity introduced by V.V. Dokuchaev (and in Romania by G. Murgoci) and modernized taking into account the objective criteria for soil characterization and identification introduced by Guy Smith and American Soil Survey

Annals of the Association of American Geographers, 1977
The United States Department of Agriculture has developed and formally adopted a new Soil Taxonomy (still popularly known as the Seventh Approximation). Existing maps of soils according to the Seventh Approximation are confusing and inadequate because the data base was weak at the time of compilation and the cartographic technique of regionalization is

Soil Properties and Classification (Soil Taxonomy)
2016The consistent use of standard procedures is one of the strengths of the National Cooperative Soil Survey in the USA. Together these standards ensure that soil descriptions and data can be compared, grouped, classified, and interpreted effectively. Important standards include horizon nomenclature to convey soil-forming processes and genetic history of ...
