Soil Guideline Values (SGVs) are figures which are used in non-statutory technical guidance for assessors carrying out risk assessments to determine whether land is considered "contaminated" under United Kingdom law, that is "land which appears to... be in such a condition, by reason of substances in, on or under the land, that (a) significant harm is being caused or there is a significant ...
The values presented below are from Annex 1, Table 1, "Groundwater target values and soil and groundwater intervention values". In previous versions of the Dutch Standards, target values for soil were also present. However, in the 2009 version, target values for soils have been deleted for all compounds except metals.

As part of this framework, generic Soil Guideline Values (SGVs) have currently been derived for ten contaminants to be used as "intervention values". [32] These values should not be considered as remedial targets but values above which further detailed assessment should be considered; see Dutch standards.
The result, the soil value, expresses the relative net income that, under normal and proper management, is determined only by the profitability of the soil. Additions or deductions in this value to take account of variations in yield due to terrain and climate (e.g. average annual temperature) give the field value ( Ackerzahl ).
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt):
A soil family category is a group of soils within a subgroup and describes the physical and chemical properties which affect the response of soil to agricultural management and engineering applications. The principal characteristics used to differentiate soil families include texture, mineralogy, pH, permeability, structure, consistency, the ...
Soil quality in agricultural terms is measured on a scale of soil value (Bodenwertzahl) in Germany. [6] Soil quality is primarily measured by chemical, physical, and biological indicators because soil function cannot easily be measured directly. [7] Each of these categories comprises several indicators that provide insight into overall soil ...
