“…Profile classes are therefore distinguished from soil map units, considered as classes of delineated soil bodies (Knox, 1965) that are characterized by some degree of geographic homogeneity and that may or may not corres ond to natural soil landscape units as defined by Schelling (1970).…”

Summary The development of soil classification as a basis for soil mapping in England and Wales is briefly reviewed, and a system for future use is described. The things classified are soil profiles, and classes are defined by relatively permanent characteristics that can be observed or measured in the field, or inferred within limits from field examination by comparison with analysed samples. Profile classes are defined at four categorical levels by progressive division, and are termed major groups, groups, subgroups, and soil series respectively. Classes in the three higher categories are defined partly by the composition of the soil material and partly by the presence or absence of particular diagnostic horizons, or evidence of recent alluvial origin, within specified depths. Soil series are distinguished by other characteristics, chiefly lithologic, not differentiating in higher categories. Most of the soil groups, regarded as the principal category above the soil series, are closely paralleled in other European systems, in the U.S.D.A. system (7th Approximation with subsequent amendments), or in both. Compared with the system used hitherto, the main innovations are the use of specific soil properties to define classes at all categorical levels, and the separation at group level of classes based primarily on inherited lithologic characteristics. The soil‐profile classification provides a uniform basis for identifying soil map units, considered as classes of delineated soil bodies. When a map unit is identified by the name of a profile class, it is implied that most of the soil in each delineation conforms to that class, and that unconforming inclusions belong to one or more closely related classes or occupy an insignificant proportionate area. Map units identified by land attributes not differentiating in the profile classification are termed phases.

“…But the probabilities of the various RSGs can also be interpreted as a soil composed of the various RSGs, i.e. various diagnostic horizons or various soil processes running simultaneously or successively as has been part of soil genesis theory for a long time (Simonson, 1959;Schelling, 1970). Thereby, this provides a good means to acknowledge inter-relations between the RSGs.…”

“…From a process-oriented viewpoint, an aspect of the Pedometrics book that is likely to surprise readers is the fact that, aside from the production of maps and more recently of digital maps, little is said in the book about possible purposes pursued by pedometrics, as if the development of geostatistical methods and their application to mapping were, in and of themselves, satisfactory objectives. One could make in this context the same comments that were made decades ago by, e.g., De Bakker (1970) or Schelling (1970) with respect to soil classification. De Bakker (1970), in particular, wrote that "from an extensive survey of recent literature it appears that much is said about principles of soil classification, whereas there is often a lack of definite statements about purposes.…”
