NSI Texture Information - NSI Textures

NSI Texture data for Yorkshire, UK

The National Soil Inventory (NSI) textures data is a spatial, point dataset with 6,127 points, located in a 5km grid across England and Wales.

NSI textures provides a very detailed description of the texture of the topsoil. This data, taken from laboratory analysis of the samples from the sites, breaks the topsoil down to its constituent grainsize fraction and provides the percentage of that soil which is of that fraction.

NSI textures can be used to identify areas of topsoil heavily influenced by the presence of clay, silt or sand. This data set will be useful for those investigating the pattern of soil textures across England and Wales, for instance in the relationship between soil and underlying lithology.
