Soil Texture Points

The map covers the Nottingham-Humberside and East Anglian G-Base survey areas only. The dataset comprises 2374 analyses from a subset of G-Base surface samples (0-20cm depth) taken at a density of 1 sample per 2km2.

The texture data was captured for a joint research project between BGS, Rothamsted Research and Nottingham University, looking at methods of estimating particle size from geochemical analyses of topsoil. The work was originally published in the European Journal of Soil Science as a paper entitled Estimating particle-size fractions of soil dominated by silicate minerals from geochemistry. The particle size analysis was carried out using laser granulometry and the data available in the viewer provides percentages (totalling 100%) of clay, silt and sand content. The map portrays the data in five simplified classes of soil (see legend below). The European Soil Bureau code for the parent material underlying each sample is also provided.

These data are made available under the Open Government Licence, subject to the following acknowledgement accompanying the reproduced BGS materials: "Contains British Geological Survey materials © NERC [year]".

The services support the British National Grid and Lat/Long WGS84 coordinate systems and the data is visible when zoomed in between 1:2,000,000 and 1:50,000 scale for the 1km data and between 1:50,000 and 1:15,000 for the 1:50,000 data.
