Advanced soil geochemical atlas of England and Wales

Select an option from the list below to view high resolution images and data about soil element concentrations across England and Wales.

The Advanced Soil Geochemical Atlas of England and Wales was a joint project between the British Geological Survey (BGS) and Rothamsted Research, and is based on soil samples collected for the National Soil Inventory (NSI) by the Soil Survey of England and Wales (now the National Soil Resources Institute, Cranfield University). The maps are based on 5700 surface soil samples (0–15 cm), collected across England and Wales, that have been analysed for 52 major and trace elements (eg aluminium, calcium, rubidium, lanthanum, selenium etc). The compiled atlas is also available online for viewing as an ebook download. The data for each of the elements can be downloaded as a set of interpolated concentrations (20Mb) on a 1 kilometre grid across England and Wales.

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

The maps cover England and Wales showing interpolated values of topsoil element concentrations (mg/kg) at a 1km grid resolution.

The concentrations of aluminium were determined using wavelength dispersive X-ray fluorescence spectrometry with a lower limit of detection of 0.05 % and typical coefficients of variation of around 3% for repeated analyses of certified reference materials. The coefficient of variation (CV) expresses the error associated with subsampling and analysis; CV values of less than around 10 % suggest that analyses are reasonably accurate.

The concentrations of sodium were determined using wavelength dispersive X-ray fluorescence spectrometry with a lower limit of detection of 0.2% and typical coefficients of variation of around 6% for repeated analyses of certified reference materials. The coefficient of variation (CV) expresses the error associated with subsampling and analysis; CV values of less than around 10% suggest that analyses are reasonably accurate.
