iSOIL - Interactions between soil related sciences -
Linking geophysics, soil science and digital soil mapping

Meeting with Stakeholders (Expert Talk Fuhrberger Feld)

iSOIL: Expertenworkshop

Date: June 16, 2009

Location: Waterworks facility of Stadtwerke Hannover AG in Elze-Berkhof

Topic: Expert talk about geophysical measurements for the dertermination of pedological parameters that are to be performed in 2010 at the Fuhrberger Feld as part of the EU project iSOIL

Participants: 18 participants from administrations, organization, associations and scientific facilities

Programme:

Time Talk
10:00 – 10:05 Reception (NN Stadtwerke Hannover AG)
10:05 – 10:20 Introduction of the iSOIL project (Dr. Dietrich)
10:20 – 10:40 Previous work and intermediate results (Dr. Werban)
10:40 – 11:00 How can the Fuhrberger Feld benefit from iSOIL? (van Straaten)
11:00 – 12:00 Demonstration of measurement instrumentation / light meal
12:00 – 13:30 Discussion (presentation: Dr. Thiem)
  a) questions arising from application
  b) data stock / data exchange
  Talk about the models CANDY and CCB (Janine Krüger, UFZ)

Aim of Expert Talk
An obvious train of thought is that measurement results, that were performed on the basis of explicit practice-related questions, are of interest not only for the project but also for locally active stakeholders, who are naturally provided with the results. In return, measurements can be better planned if already existing data and information can be utilized. Hence during a workshop-like preparatory expert's meeting with selected stakeholders and scientists, adequate questions for the field campaign at Fuhrberger Feld and possibilities of mutual data exchange are to be identified.

Outcome of Expert Talk
An obvious train of thought is that measurement results, that were performed on the basis of explicit practice-related questions, are of interest not only for the project but also for locally active stakeholders, who are naturally provided with the results. In return, measurements can be better planned if already existing data and information can be utilized. Hence during a workshop-like preparatory expert's meeting with selected stakeholders and scientists, adequate questions for the field campaign at Fuhrberger Feld and possibilities of mutual data exchange are to be identified.

Since field surveys and scientific evaluation activities (validation of methods) will be conducted in 2010, local stakeholders had to be informed at an early stage about the project. For this purpose and for dissemination purposes as well, a meeting with local experts was organized on June 16, 2009 near Hannover. 18 stakeholders and end-users participated in this meeting. The meeting presented an overview about the iSOIL project and its activities and showed how the "Fuhrberger Feld" can make use of the iSOIL-project.
Topics during the discussions were some basic methodological understandings and the possibilities and limitations of the geophysical methods to be developed.
At this meeting there was also a demonstration of the technological equipment, especially the geophysical platforms. During this demonstration specific questions concerning some practical aspects of using the devices in the field were discussed, mainly focusing on problems in forested areas. During the workshop, most participants agreed, that precision farming might be of interest in some border areas of the Fuhrberger Feld. However, without restriction to the Fuhrberger Feld area, other potential applications were identified:

Agriculture precision irrigation, distinction of grassland types (permanent and facultative) according to the thickness of the humic layer potentials for land improvement by drainage as a function of existing soil compaction
Forestry Parameters of interest are: potential and actual root penetration depth, nutrients, moisture, organic matter, grain size distribution, compaction depth of groundwater level
Groundwater Priority areas for groundwater protection measures related to the method of nitrogen-surplus according to Dr. Springob: geophysical overview mapping to detect areas for detailed geochemical analysis Spatial allocation of denitrification zones within the aquifer, Detection of deeper layers with a surplus of organic carbon, which turn to be a source of nitrate emissions due to aeration due to the drawdown of the groundwater levels (e.g. by pumping, by drainage etc.)

The discussions with local the stakeholders and practitioners and with the scientists involved in iSOIL revealed a typical conflict: scientists are interested to follow an accurate scientific procedure; practitioners are interested in solving problems (at affordable costs). However, practical measurements will be planned in a way that some added value for local stakeholders can be expected.
