Peter ya nos habl\u00f3 personalmente de este tema en la Conferencia Internacional de Geograf\u00eda de Suelos (M\u00e9xico).

Dear all,<\/p>\n

\u00a0
\nThis is brief information for all members of IUSS Working Group WRB:<\/p>\n

1. The \u00abGuidelines for constructing small-scale map legends using the WRB\u00bb are now electronically published as an amendment to WRB 2006\/07 <\/strong>and available at the WRB homepage at FAO<\/strong>:<\/p>\n

http:\/\/www.fao.org\/nr\/land\/soils\/soil\/wrb-documents\/en\/<\/a>. Comments to these guidelines are welcome. (\u2026)<\/p>\n

Introduction<\/span><\/strong><\/p>\n

In this addendum to WRB 2006, first update 2007, guidelines are provided to construct map units (or soil typological units) and map legends for scales of 1:250 000 and smaller<\/strong>. For terms and definitions in these guidelines the user is referred to the above publication, which can be downloaded from the WRB website<\/strong>:<\/p>\n

http:\/\/www.fao.org\/ag\/agl\/agll\/wrb\/doc\/wrb2007_corr.pdf<\/a>.<\/p>\n

When classifying soils, the WRB is capable of <\/strong>indicating most of the soil\u2019s properties, and in most cases the result is a quite satisfactory and informative soil name. However, when generalization is required, e.g. in mapping, important information may not show<\/strong>, depending on how the generalization is carried out. Although WRB was not primarily designed to serve mapping purposes, it is increasingly used for that. This addendum has been developed to serve the need for small-scale mapping<\/strong>.<\/p>\n

In the above-mentioned WRB publication it is suggested to use for small scale maps the prefix qualifiers only and for large-scale maps additional suffix qualifiers<\/strong>. If this approach is taken with the current configuration of the qualifiers, important information on certain soil characteristics may not be revealed for small-scale maps. For example<\/strong>, the occurrence of clay skins (Cutanic) is recognized at prefix level, and, when generalizing, Luvisols (and related soils) become Cutanic Luvisols or Cutanic other soils, which for temperate and subtropical regions does not give satisfactory differentiation. Similarly, Rhodic in Ferralsols and Nitisols, and Xanthic in Ferralsols, important qualifiers to indicate their environmental setting and geological relationship, are suffix qualifiers, yielding in generalizations only Haplic Ferralsols and Nitisols.<\/p>\n

These guidelines are based on the following considerations: (\u2026)<\/p>\n
