The day began with a series of inspiring presentations in which experts provided an overview of innovations and trends related to microbial inoculants. By using concrete examples, they illustrated how these inoculants can contribute to a sustainable cropping system. A well-known example is the inoculation of soybean seeds with nitrogen-fixing Rhizobium bacteria to ensure that the protein content of soybeans is sufficiently high for food processing. In the afternoon, participants had the opportunity to see firsthand how microbial inoculants can be applied in practice on the farm during interactive workshops. This created a strong link between theory and practice.
Where does the research stand?
Within OH-FINE, three Flemish practice- and research institutions (Inagro, Hooibeekhoeve, and ILVO) combine their expertise and experience with microbial inoculants. The most recent trial was established in 2025 at the Agroecology Research Platform in Hansbeke (PHAE). A commercial product (Soil Activator) containing Bacillus & Pseudomonas as well as two self-prepared products (Jadam Microbial Solution and EM Cubana) made from microorganisms in forest litter were tested in a winter wheat trial. The treatments were applied experimentally using a drone, which allowed for flexibility in timing. However, these drone applications are not yet common practice in Flemish agriculture. Another trial is planned for 2027.
Where does practice stand?
In Flanders, several pioneers are active with years of experience, both locally and internationally. Lieselot Van der Veken (Pro Terra Agro) and Luc Meeuwissen (Napagro/AgroSymbio) shared their practical experiences on the use and effects of inoculants in real-world agricultural settings and explained how farmers can get started on their own farms with home-made microbial inoculants. Additionally, two farmers shared their experiences and learnings in an engaging panel discussion. This conversation served as a strong bridge to the hands-on workshops in the afternoon.
During the workshops, various applications and preparations involving microbial inoculants were demonstrated: soybean inoculation, the preparation of EM Cubana and SuperMagro (spore mix), the production and use of compost extract and compost tea, as well as how to assess the vitality of microorganisms under the microscope using preparations. Clearly, a good collaboration between plants and microorganisms in the soil is essential for a sustainable and regenerative agricultural system. Although a great deal of knowledge already exists about microorganisms and their application through microbial inoculants, many uncertainties remain, and much is still left to discover.
