BD Sol – Dynamic Management of Agricultural Potentialities (GDPA)- Hérault

Agricultural potentials represent the capacity of a soil to accommodate crop production according to soil climatic conditions. These potentials can also be managed taking into account other parameters (e.g. irrigation networks, socio-economic, land-based data, etc.). A visualisation of the data is also available at the following link:
Regional mapping

The GDPA tool is based on the study of three soil cropping potentials:
field crops, quantitative viticulture (PGI base) and market gardening.
A synthesis of the three, the global cultural potential makes it possible to understand the capacity for cultural diversification of a soil.
Thus, the soils most conducive to diversification (strong global potential) allow the development of a large number of crops.

The GDPA decision support tool was established in partnership with the Association Climatologique de l’Hérault (now integrated into the Department), the Department of Hérault, the Chamber of Agriculture of Hérault and INRAE in 2012/2013.
It results from the analysis and processing of agropedological data from the soil database, established and digitised in 2011.
The tool is currently maintained by the Department of Hérault.
It has been the subject of an update following a work complementing the soil database carried out by the Métropole de Montpellier in 2018/2019.

Completeness Limits:
The cartography ** does not cover all the Heraultese communes, nor the total area of each municipality.
As a result, uninvented soil means a lack of data, no conclusion as to the potentiality of this soil can be inferred from this.**

Mapping precision limits:
The mapping of cropping potentials is the scale 1/10 000th (so-called “communal” scale).
Thus, superposition with cadastral plans made on larger scales is not recommended by experts.

Different ** confidence indices** allow to translate the uncertainty of the cartographic limits.

The data made available should therefore be used with caution according to the accuracy limits.
The department of Hérault and its technical and scientific partners cannot be held responsible for inaccuracies in the databases and for inappropriate uses of the databases.
