description

The INRAE InfoSol unit, mandated by the Gis Sol, coordinates the French Soil Monitoring Network (RMQS) set up to assess the quality and evolution of soils in France. A local trained team collects management data through a survey with farmers or operators for each site and campaign. The initial objective of collecting all soil-related management data, answering multidisciplinary uses, has faced collection difficulties and lengthy interviews. Hence, survey forms were revised before the second campaign, started in 2016. The new forms were tested and improved for two years, and the data collection strategy was tuned. In order to analyze the first responses and to suggest improvements, the study was based on four axes: 1/ the assessment of collected data utilization by RMQS-related research programs, 2/ the quality of the form filling, 3/ the feedbacks of the investigators and also the utilization of other data sources to collect management data. From cross-reference of these axes by question, rules have been suggested to improve the surveys. In addition, this study made it possible to initiate the implementation of a new collection strategy, not only linked to the RMQS campaign of fifteen-year gap, but with a frequency of four years to assure a temporally continuity of collected data from the parcel and the farm. Finally, the storage of data, using the information system AGROSYST, is being evaluated.
