Soil geography and land evaluation¶
Soil geographic databases¶
An attempt to catalogue all freely-downloadable primary soils information usable in a GIS. Some of the linked sites also have interpreted information.
Access ISRIC’s WoSIS Soil Profile Database, using R Markdown scripts. WoSIS is explained in this paper (DOI: https://doi.org/10.5194/essd-9-1-2017)
Processing the Harmonized World Soil Database (Version 1.2) in R
The HWSD is a harmonized map and linked attribute table of the World’s soils, at a nominal scale of 1:1M. It is intended for global or regional modelling. This semi-expert approach, based on legacy maps and expert judgement, has been somewhat superseded by ISRIC’s SoilGrids 250m resolution raster layers.

Data source for this paper
A computer program that allows land evaluators to build expert systems to evaluate land according to the method presented in the Food and Agriculture Organization’s “Framework for Land Evaluation” (1976) and subsequent Guidelines. Last updated 1996, runs under Microsoft MS-DOS v2.3 or higher, and under MS-DOS emulators.
Simulates subdivisions of USDA Soil Taxonomy soil moisture & temperature regimes for well-drained soils, from a time-sequence of monthly climate data. These pages also have links to more modern methods.

This program has since become a Windows program (sorry I can’t find a link) but this manual explains the principles of the simulation models.
