Data — Lorraine Regional Soil Database — Regional Pedological Reference (RRP) Alsace at 1/250 000th — 2011

The data collected relate to soils, the products of alteration, reshuffle and organisation of the upper layers of the earth’s crust under the action of life, atmosphere and energy exchange manifested there (Aubert and Boulaine). The thickness of the described medium rarely exceeds 2 m. The data concern, inter alia, the physical characteristics of soils (thickness, pierrosity, structure, panulometry, etc.), chemical parameters (pH, organic matter, Cationic Exchange Capacity (CEC)...) but also water characteristics of soils. Information on terrain, land use, hydrology and geology is given for guidance. The soil nomenclature is based on the 1995 Pedological Reference. The soil units described are also attached to the World reference Base (WRB). These data may be useful for any study requiring spatialised soil information (production of agricultural or forest biomass, quality and quantitative management of water, biodiversity, carbon storage, erosion risk, spatial planning, landscape analysis, archaeology, etc.) The Alsace soil database is managed by the Association pour la Relance Agronomique en Alsace (ARAA) and complies with the specifications of the national inventory programme (IGCS). There are several databases at different scales. In the Alsace Regional Pedological Reference (RRP) at 1/250 000th, 82 soil map units are described and 377 types of soils cut into 1463 strata. Depending on the type of information requested and the need for additional expertise, different terms and conditions of access to this database are defined. A selection of some parameters from this database is available in Open Data (see associated resources and metadata sheet DONNEES OUVERTES — Extract regional soil database of Alsace — Regional Pedological Reference (RRP) Alsace at 1/250 000th — 2011)
