Biochar and flowering areas in vegetable production: optimizing practicality and ecological benefits (PK-BIG)
Climate change and the biodiversity crisis are among the most pressing challenges facing agriculture. The application of biochar (BC) can contribute to climate change adaptation by promoting plant root growth and stimulating the long-term build-up of soil organic matter. Flower strips increase biodiversity in intensively used cultivated landscapes. Both measures are known to many farmers and are partly applied, but their potential is not yet fully exploited. BC is hardly used in vegetable production due to a lack of practical recommendations and experience in application. Flower strips are usually sown only as annuals in vegetable production, although perennial flower strips show a higher ecological and presumably also agronomic benefit. In the present project, crop-specific application recommendations and application techniques for BC for cabbage / lettuce are developed and the barriers to the establishment of perennial flower strips (pest pressure, public perception, legal-organizational aspects) in vegetable production are investigated and reduced.
Results and the Final report will be found here, as soon as the project is completed.
The use of biochar-based fertilization is expected to lead to additional yields in the range of 5-10% at constant nutrient input. The conversion to perenniality improves the positive ecological effects of the flowering areas and leads to higher biodiversity in the cultivated landscape. The combination of BC and flowering strips serves to adapt to climate change and its consequences in the form of extreme weather events and increasing pest pressure. Concrete concepts are available on how perennial flowering strips can be implemented despite short-term leases. The BC industry has recognized the importance of vegetable production and is now continuing to develop specific products for this sector.By involving the entire value chain from farmer to retailer and a communications agency, topics such as climate protection, adaptation to climate change and the promotion of biodiversity are communicated as a unit and a positive public perception of these areas is created.
