The World Reference Base for Soil Resources (WRB) is an international soil classification system for naming soils and creating legends for soil maps. The currently valid version is the fourth edition 2022. [ 1 ]
ISRIC is a regular member of the ISC World Data System, and is known as WDC-Soils since 1989. [4] ISRIC's main open access databases include WoSIS, [ 5 ] a large database of quality-assessed and standardised soil profile data for the world, that has been used for producing soil property maps at 250 m resolution, with quantified uncertainty,for ...
SoilGrids1km is a collection of updatable soil property and class maps of the world at a resolution of 1 km produced using state-of-the-art model-based statistical methods. Presents estimates (means and 90% confidence intervals) for pH, texture (sa, si, cl), organic carbon and more for 6 depth layers up to 2 m depth. Harmonized World Soil Database

Excavating a soil monolith (Kalimantan, Indonesia) The World Soil Museum (WSM) displays physical examples of soil profiles representing major soil types of the world, from the volcanic ash soils from Indonesia to the red, strongly weathered soils from the Amazon region.
The EuDASM is a common platform established by Joint Research Centre in Italy of the European Commission and the International Soil Reference and Information Centre(ISRIC) of Wageningen University in The Netherlands to store soil and related maps in digital format and to provide free access to the global community (Researchers, University ...
The FAO soil map was intended for mapping soils at a continental scale but not at local scale. In 1988 the FAO published a Revised Legend with 153 Soil Units forming 28 Major Soil Groupings. It serves as basis for the Harmonized World Soil Database. In 1998 this system was replaced by the World Reference Base for Soil Resources.
From 1984 he was a professor of soil science at KU Leuven. Building on the earlier work with the Soil Map of the World, Dudal was also engaged in crafting World Reference Base for Soil Resources as secretary of the International Reference Base for Soil Classification from 1986 through 1992. [1]
Lixisols are a Reference Soil Group of the World Reference Base for Soil Resources (WRB). [1] They are soils with subsurface accumulation of low activity clays and high base saturation. They develop under intensive tropical weathering conditions and subhumid to semi-arid climate. [2] Soil profile of a Lixisol
