For Establishing the Global Geochemical Reference Network the whole globe must be sampled. Hence, the sampling procedure must be consistent for all sample types and, therefore, is standardised to be applicable in all morphoclimatic environments. Taking into consideration the mode of formation of residual soil, stream, overbank and floodplain sediments, the medium that needs the greatest attention is residual soil. The residual soil chapter has two annexes. The first describes the characteristics of the 28 major soil mapping units, namely Regosols, Leptosols, Gleysols, Cambisols, Podzols, Arenosols, Calcisols, Histosols, Luvisols, Fluvisols, Podzoluvisols, Acrisols, Ferralsols, Kastanozems, Chernozems, Phaeozems, Solonetz, Vertisols, Lixisols, Solonchaks, Gypsisols, Greyzems, Andosols, Planosols, Nitisols, Plinthosols, Anthrosols and Alisols. The second annexe provides annotated soil profiles and instructions on how to overcome sampling difficulties.  For each soil type websites are provided for additional information.

 

Peter Schad, who provided most of the soil profile photographs, displayed in Annexe 'A3.2.1. Residual Soil and Humus Sampling: The Soils of the World', has informed us about the following recently published book, which is worth consulting:

 

Zech, W., Schad, P. & Hintermaier-Erhard, G., 2022. Soils of the World. Springer, 256 pp.; https://link.springer.com/book/10.1007/978-3-540-30461-6. The book is illustrated with 321 colour illustrations.

 

Further, interested scientists that would like to study soil in depth, the fourth edition of the following book and website are worth consulting:
