Digital Soil Mapping Survey
The results of this survey and more information on the Digital Soil Maps are published in the article:
Diafas, J. Panagos, P., Montanarella, L. 2013. Willingness to Pay for Soil Information: A Choice Experiment Approach. Vadose Zone Journal . In Press. doi:10.2136/vzj2012.0198. Contact the Authors to get a Copy of the Article.
In this publication, the authors estimated the economic value of soil information generated by a host of new proximal and in situ geophysical methods for the assessment of the following soil properties: carbon content, water content, clay content, bulk density, and soil depth. Therefore, they designed and applied a choice experiment as a technique in valuing soil information. Spatial resolution and map interpretation were also included as attributes, in addition to the soil properties. The survey reveals potential end-users and for what purpose they would want to use the offered maps. The authors were able to estimate the end-users' willingness to pay for individual features of the maps. One result is a particularly strong preference for maps of high resolution and accuracy that offer map interpretation in addition to a number of soil properties.
Thank you for participating in this Survey.

The DIGISOIL Consortium involving the SOIL Action of the JRC, is currently in the process of developing a new technology for the assessment of soil properties and soil degradation indicators that can be used for producing high quality geo-referenced soil maps.
The technology consists of :
- a hardware machine usually a truck or a quad integrating a platform that employs proximal and ground-based soil scan systems (sensors) that can measure accurately (0.5 – 2 m) the signals from the soils;
- A software which transform the signals into the following soil properties:
- Soil texture
- Water content
- Organic matter
- Soil bulk density
- Electro conductivity
- Carbonate rate
- Soil depth
- Compaction depth
|Following these measurements, the technology leads to detailed geo-referenced maps of soil properties.
Moreover, from the maps, it is possible to offer end user-targeted services, such as fertilizer recommendations and/or analysis of soil risks degradation intensity.
Before deploying the technology, and in order to better target it to the end user, we are launching a survey which aims to assess the economic feasibility of such an undertaking and its relevance to the end user.
To this aim, as a potential end user, we kindly ask you to indicate whether you are interested in making use of this technology and if so, which services you wish to employ. You should fill out first the following questionnaire which takes less than two minutes. You will be then approached after two weeks to fill out a second questionnaire which will take you five minutes of your time. Thanks a lot in advance for your precious contribution.
