Download the data

This dataset consists of mid-infrared (MIR) spectra measured on 427 archived soil samples from arable and grassland habitats across Great Britain in 2007. Data on diffuse reflectance spectra were obtained from subsamples of finely ground soil, recorded as absorbance values for wavenumber range 4000-400 cm-1.

The soil samples were collected as part of the Countryside Survey monitoring programme, a unique study or 'audit' of the natural resources of the UK's countryside. The analyses were conducted as part of study aiming to quantify how soil quality indicators change across a gradient of agricultural land management and to identify conditions that determine the ability of different soils to resist and recover from perturbations.

Provenance & quality

Soil samples were collected in 2007 by Countryside Survey field surveyors, who were provided with a field sampling manual and underwent training for sample collection and processing. Protocols were also provided to cover all aspects of processing of the soil cores from logging in of cores as they arrived at the laboratory to basic measurements, chemical analysis and archiving the final samples. Soils were sieved to 2 mm and air-dried before storage.

Each soil sample was scanned twice to obtain repeat spectra, with the sample cup being rotated 180 degrees between scans, and the average of these two spectra included in the dataset. Each individual spectrum (i.e. both from the paired scans) was visually inspected and those containing scanning errors were discarded.

All MIR analyses were conducted at the Organic Geochemistry Facility, BGS (contact chv@bgs.ac.uk for details).
