Guidelines for Quality Management in Soil and Plant Laboratories

This page attempts to catalogue all freely-downloadable primary soils information usable in a GIS either as ‘points’, lines, polygons or grids (‘rasters’). This compilation has been maintained first at University of Twente/ITC (1997-2014), then at Cornell University (2014-2017), and now at ISRIC - World Soil Information by guest researcher David G. Rossiter.
