NSI soil sample locations in England and Wales

The National Soil Inventory (NSI) is a set of soil samples at a density of one sample per 25 km2 collected across England and Wales. The original sample programme during the 1980s, and subsequent partial re-sampling programme during the 1990s, provide a status, stock and change assessment of key soil properties such as pH and key chemical elements. The data are held and maintained by the National Soil Resources Institute (Cranfield University).

In a joint project between BGS and Rothamsted Research this dataset was re-analysed for 50 elements. The interpolated maps for these elements are available in the UK Soil Observatory map viewer.


Scotland NSIS 10km

The National Soil Inventory of Scotland (NSIS) is a set of soil samples at a density of 1 sample per 25 km2 collected across Scotland. The original sample programme (during the 1970's and 1980's), and subsequent resampling programme (from 2007 - 2010) provide a status, stock and change assessment of key soil properties (such as nutrient levels).

The data are held and maintained by the James Hutton Institute and can be found in the Scottish Soil database and website, as well as in the UK Soil Observatory map viewer.


Countryside Survey data access

The Countryside Survey Soil data has been collected over three surveys: 1978, 1998 and 2007. Samples are collected from 591 (1 km2) squares across Great Britain. Data are available on the total stock and inter-survey change of a wide range of soil attributes including soil carbon, nutrients, heavy metals and invertebrates.

Both summary and raw data by country, broad habitat, vegetation type, and soil organic matter category can be downloaded from Countryside Survey data access. You will need to become a registered user to access their data.

Selected interpolated maps for these elements are available in the UK Soil Observatory map viewer.

*Please note that available data does not contain spatial coordinates for Countryside Survey sampling locations as they are based on anonymous site-survey protocols.


Geochemical Mapping of Agricultural Soils in Europe

The Geochemical Mapping of Agricultural Soils in Europe (GEMAS) project collected soil samples during 2008 at a density of 1 site per 2500 km2 from grazing and arable fields across the UK. Data are available on a wide range of characteristics including total C and S, total organic carbon (TOC), cation exchange capacity (CEC), XRF analysis of multiple elements, pH, and particle size distribution (PSD) analysis.

The data has been reported, further information can also be obtained from the GEMAS UK partner.
