TRIO - Transformative mixed culture systems for One Health

This page contains automatically translated content.

Project objective:

The scientific guiding principle of TRIO is the development of sustainable and climate-resilient crop production through an ecological-functional intensification of cultivation systems based on the mixed cultivation of plants with distinctly complementary strategies of resource appropriation. The scientific goal is an improved understanding of complex soil-plant, plant-plant, plant-microbiome and plant-agricultural ecosystem interactions as a basis for sustainable plant production. Under the stress conditions of climate change, this is characterized by increased water and nutrient uptake from previously underutilized soil areas, more complete use of irradiation, higher storage of atmospheric carbon in the soil, more diverse, more resilient microbiomes in soil, roots and crops, greater attractiveness for flower-visiting insects and higher yields and product quality. The increase in production and quality through the intensification of ecological processes, modeled here as an example for Hesse, is geared towards the health of soil, plants, animals, people and the planet and thus follows the "One Health" approach.

Using an experimental platform developed across contrasting locations, TRIO will quantify and monetarily evaluate the ecosystem services of new combinations of resource-complementary crops with scientists with different expertise using and further developing state-of-the-art methods (including isotope labeling, remote sensing, DNA metabarcoding, true cost accounting). Model-based spatial and temporal upscaling of the experimental data generates site-specific knowledge on climate- and biodiversity-protecting and climate-change-adapted cultivation systems for the production of high-quality, diverse food in Hesse, which is directly incorporated into agricultural practice and advice via the associated partners. Quantitative market research approaches are used to determine the preferences / values of various stakeholders.

Project structure:

The three university sites in Kassel, Giessen and Geisenheim are working in the four project areas of soil-plant interactions, agricultural biocenosis, modeling and upscaling and socio-economic evaluation at four trial sites in Hesse (trial sites in Frankenhausen (University of Kassel), Weilburger Grenze and Groß-Gerau (JLU Giessen) and Darmstadt (Forschungsring e.V.), supplemented by eight practical sites in Hesse and a very dry site at ZALF in Brandenburg. The field trials are complemented by large container trials at the Kassel (LLH) and Geisenheim sites.
