Theia Digital Soil Mapping experts group produces an interactive mapping of soil properties in Brittany, documenting the following variables:

• Cation exchange capacity (CEC),
• pH,
• carbon content,
• rate of coarse elements,
• particle size fractions (clay, silt and sand content),
• erosion.

An online application allows you to view predictive maps of soil properties on: https://geosas.fr/solsdebretagne/#
