In this publication, we present the results of an acceptance study in two case study regions in Germany. We investigated farmers' and other soil experts' perceptions of subsoil amelioration as an approach to adapt to climate change. In addition, we analyzed the factors that influence their willingness to adopt specific measures to improve the subsoil. Applying q-method and focus groups, we surveyed overall 86 actors in the agricultural sector. The article is published in Frontiers in Agronomy, Volume 3, April 2021 and is available for download.

In June 2019, the stakeholder workshop "Optimal soil management to ensure yield capacity & acceptance analysis of measures to upgrade the subsoil" of the BMBF-funded BonaRes project "Soil³ – Sustainable Subsoil Management" took place in Moltzow (Mecklenburg-Western Pomerania). This workshop is part of a series of workshops with the aim to discuss and gather the prevailing opinions on subsoil management measures with the help of an acceptance analysis. Ecologic Institute researchers discussed with farmers and other ecological actors under which conditions they would implement or support these measures.

In January 2019, the stakeholder workshop "Using the Subsoil to Better Prepare for Droughts – An Acceptance Analysis of Measures to Enhance the Subsoil" of the BMBF-funded BonaRes project "Soil³ – Sustainable Subsoil Management" took place in Bonn. The aim of the workshop was to discuss the prevailing opinions on subsoil management measures. Ecologic Institute researchers discussed with farmers and other ecological actors under which conditions they would implement or support these measures. The protocol is available for download.

Hidden beneath the humus-rich topsoil, the subsoil usually receives little attention in agricultural practice. Yet, plants cover between 10 and 80% of their nutrient and water needs from subsoils. Measures to improve the subsoil could help in bridging droughts and stabilising yields. But how do farmers and other societal actors perceive different methods for subsoil management? Ecologic Institutes's Ana Frelih-Larsen, Mandy Hinzmann and Sophie Ittner published the first exploratory research results on the societal acceptance of subsoil management in the open access journal Sustainability.

Fertile soils are an indispensable resource for agriculture and the Bioeconomy as a whole. Subsoils contain a major part of the nutrients essential for plants, a resource potential that has thus far not yet been fully understood nor used. In order to harness this untapped potential, the Soil³ project examines the subsoil processes and application of alternative subsoil management measures. The Ecologic Institute will conduct research on the costs, benefits and social acceptance of these measures.
