The major challenge of the BonaRes system approach was to bring together researchers from different soil and agriculture-related disciplines and to find a common language. In addition to interdisciplinary collaboration within the projects, this was achieved through thematic workshops, joint publications, status seminars and conferences.
A soil-related repository for research data and long-term field experiments, an online map of European long-term field experiments and a soil profile database have been set up. The data from the BonaRes and Rhizo4Bio networks and external projects are made available for free re-use via this platform in accordance with the latest standards.
A particular scientific challenge of the BonaRes Centre was to bring together existing and newly acquired knowledge about soil processes and their complex interactions. The main focus was on understanding the importance of soil organisms and their interaction in a physically and chemically very heterogeneous environment. The ‘Knowledge Library’ was set up, a freely accessible knowledge database that summarizes the knowledge available in the literature on the influence of management measures on soil functions on a site-specific basis.
In collaboration with the joint projects, the modelling tools BODIUM and BODIUM4Farmers (in German, for the area of Germany) were developed, which are able to predict the effects of soil management measures on soil functions, taking into account local conditions in terms of soil type, land use and climate. As an important basis for the modelling, high-resolution maps of relevant soil properties were generated for the scale of Germany using various methods of regionalization. The systemic approach also takes into account the interactions with social and economic systems, which have a significant influence on soil management decisions and thus on the natural environment. Soil-promoting management options are analyzed in terms of their social, economic and ecological effects, including under the framework conditions to be expected in the future, and political control instruments are proposed on this basis. This can be expected to make an important contribution to a sustainable balance of interests between economy and ecology.
The BonaRes Centre has contributed to the perception of soil as an essential resource through various public relations measures, such as trade fair appearances, the creation of fact sheets, brochures and teaching materials, the Citizen Science campaign ‘Expedition Erdreich’ and the patronage of the Soil of the Year 2024 ‘Arable Soil’. Products and services as well as scientific results from the BonaRes programme are made permanently available via a web portal (bonares.de).
