BonaRes foresight interviews 2017 - quantitative answers

On the basis of a literature-based foresight study, we identified drivers, trends and possible developments of soil management in Germany, from which we derive challenges and opportunities, and corresponding research needs (Techen, AK. & Helming, K. Agron. Sustain. Dev. (2017) 37: 64. https://doi.org/10.1007/s13593-017-0473-3). In this context, soil management is broadly understood, that is, far beyond tillage, as the agricultural practices that affect all soil functions. We asked 22 experts in 19 interviews to validate and supplement the results of the foresight study with us.
The interviewees were chosen based on the area of their expertise. Within this constraint, we considered experts who were known to us. Several of them are members of the advisory board of the BonaRes Centre. They had already been chosen for this committee because of their distinguished expertise and relevant roles for agricultural soil management. The names and affiliations of the interviewees are given in the supplemental information.
The questionnaire had a German and an English version and contained questions with structured and quantified answers as well as open questions.
The interviews were partly conducted via telephone, partly face-to-face. The interviews were recorded. They were then transcribed, partly by us, partly by a transcription company. The quantitative statements were entered into the data table directly from the filled questionnaires. For the verbal comments, variables were constructed which for the most part are commentaries to quantitative questions. The verbal statements were entered from the transcripts into the data table, assigned to the respective variables.
In this data file only the quantified answers are given.
