The National Soil Resources Institute market a wide range of soil and soil-related datasets. These are outlined below:

NATMAP datasets represent the authoritative digital soil map for England and Wales. There are various data products derived from the National Soil Map, each suitable for different tasks; these are outlined below.

NATMAP Vector

If you are looking for the best quality available map data with national coverage of both England and Wales, we recommend NATMAP Vector. This flagship dataset has many uses from regional assessments, catchment characterisation, site assessment and, combined with our 'SOILSERIES' set of soil property datasets, computer modelling.

• Number of soil classes: ~ 300;

• Scale: 1:250K;

• Map units: Soil Associations.

NATMAP Soilscapes

NATMAP Soilscapes is a simplified version of the full National Soil Map, having an easy-to-understand map legend. Soilscapes is ideal for simple descriptive overviews of the soils and soil landscapes of a region, as well as the relationship between soil and the environment.

• Number of soil classes: ~ 30;

• Scale: 1:250K;

• Map Units: Soilscape Units.

NATMAP 1000 & 5000

These are gridded vector versions of the National Soil Map, where the squares represent 1km x 1km, and 5km x 5km gridcells respectively. These are suitable for modelling situations, but do not provide the full spatial detail of NATMAP vector.

• Map Units: Soil Series % within polygon;

• Resolution: 1 km, or 5 km gridcells.

SOILSERIES attribute datasets have been developed to link to the NATMAP datasets (excepting NATMAP Soilscapes) to provide more detailed soil information specific to the users needs. These are outlined below.

SOILSERIES Info

This includes basic soil information including the modern definition of soil series.

  More details ...

SOILSERIES Pesticides

This dataset is useful for modelling and predicting the movement and attenuation (fate and behaviour) of pesticides in soil, based on leaching and runoff classes.

  More details ...

SOILSERIES Hydrology

This detailed dataset contains hydrological properties of the soil and associated rivers. It is useful for many types of hydrological models.

  More details ...

SOILSERIES Agronomy

This provides information on the available soil water for mainstream crops for the different soil types across England and Wales.

  More details ...

SOILSERIES Leacs

The Leacs data product is used by almost all the major water companies as part of their pipe replacement programme as part of their strategic Asset Management Plans (AMPs). Because soils are variably aggressive to pipes, knowing which pipes will need replacing first can save significant sums.

HORIZON Fundamentals

These data detail the properties of each of the soil horizons (layers) from the topsoil to the parent material. Information includes textural propterties along with layer thicknesses. It provides different information for the same soil series under different land uses.

HORIZON Hydraulics

These data detail the properties of each of the soil horizons (layers) from the topsoil to the parent material. Information includes hydraulic propterties along with layer thicknesses. It provides different information for the same soil series under different land uses.

The National Soil Inventory, or NSI, covers England and Wales on a 5km x 5km grid and provides detailed information for each intersect on that grid. Collectively, NSI data are statistically representative of English and Welsh soils and they offer a valuable foundation for the future monitoring of soil quality.

  More details ...

NSI site

This dataset describes the site of the NSI point, including landuse and lithological information.

  More details ...

NSI profile

This dataset gives a very detailed description of each soil horizon (layer) in the soil profile.

  More details ...

NSI topsoil

This dataset gives detailed measurements from a bulked sample of the topsoil, of pH, organic carbon and over 20 elements (total and available) by a variety of laboratory methods.

  More details ...

NSI textures

This dataset describes the soil texture, providing % information for the texture grades (i.e. sand (4 grades), silt & clay).

  More details ...

NSI features

This dataset provides depth information to the various diagnostic layers within the soil profile.
