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 ...
Digital soil mapping (DSM) in soil science, also referred to as predictive soil mapping [1] or pedometric mapping, is the computer-assisted production of digital maps of soil types and soil properties. Soil mapping, in general, involves the creation and population of spatial soil information by the use of field and laboratory observational ...
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 ]
World Soil Museum, ISRIC - World Soil Information, Wageningen campus, The Netherlands. 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.
Using Geographic Information Systems (GIS), Remote sensing and emerging technologies a global soil map will be created to represent different soil types. [5] The consortium is led by the ISRIC-World Soil Information, whose mandate to increase knowledge on soils through data collection and dissemination and development of technologies and ...
Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) [1] and claimed to be successfully in use on over a million acres (4,000 km 2) of farmland worldwide.
A soil map is a geographical representation showing diversity of soil types or soil properties (soil pH, textures, organic matter, depths of horizons etc.) in the area of interest. [1] It is typically the result of a soil survey inventory, i.e. soil survey .
A Cambisol in the World Reference Base for Soil Resources (WRB) [1] is a soil in the beginning of soil formation. The horizon differentiation is weak. This is evident from weak, mostly brownish discolouration and/or structure formation in the soil profile. Distribution of Cambisols
