Soil Supply

Soils are supplied (with specified ranges of clay, silt, sand, organic matter and pH) from around 30 sites across England and mainland Europe. We also supply most of the seven soils listed by the OECD for adsorption-desorption studies and also soils of a specific taxonomic classification.

Site location, sampling and intermediate storage is carried out according to ISO 10381-6. Most of our source sites have not been sprayed with pesticides for at least 5 years and we maintain regular contact with our landowners and farmers to ensure that the sites maintain that status.

Example Supply Sites

Site E1 - Brierlow, Derbyshire UK

This grass field within the Peak District National Park is used for low-input cattle fattening and forage production and is the source of one of our most frequently supplied soils (a very slightly acid silt loam). The tenant farmer uses no pesticides and reports that the outgoing tenant (who had the land for 10 years) used neither sprays nor fertiliser.


Site Fr1 – St Bauzille de la Silve, Herault, France

This low organic matter calcareous clayey soil is from an organic vineyard within the Herault area of Languedoc in France. The vineyard supplies grapes to the Mas de Janiny organic winery based in Saint Bauzille de la Silve. There has been no pesticide use in the vineyard for many years; all weed control is by harrowing and disease control is by organic methods.


Site Sp4 – Riet Vell Farm, Ebro Delta, Spain

This calcareous clayey soil is from the 50 ha Riet Vell paddy rice farm on the delta of the River Ebro in northern Spain. There has been no pesticide use on the land since 2001. A contrasting slightly acid loam soil is available from an organic paddy rice field on the French Camargue.
