Guidebook. July 22-27, 2017 3 FOREWORD International WRB Soil Classification Field Workshop in Latvia and Estonia is a great opportunity for Soil Scientists to stimulate deep reflections on the strong links between soil classification and soil sustainable management and conservation as well as to develop discussion and WRB approbation in the boreo-nemoral region, where soils are influenced by very complex fac- tors and soil processes. Soils are developed mainly on Late Weichselian glacial deposits (formed by loamy sand, sandy clay, loam, clay, gravel, sand) and altered to some extent by postglacial aeolian, marine, lacustrine, alluvial and mire sediments, as well as formed on pre-Quaternary sedimentary rocks. This workshop will look at differently formed automorphous, semihydromor- phous and hydromorphous soils (23 soil profiles and according to WRB soil classification – 12 soil groups (Gleysols, Podzols, Cambisols, Luvisols, Calcisols, Planosols, Histosols, Arenosols, Retisols, Fluvisols, Phaeozems
