Das Biodiversitätspotential - ein Ansatz zur Analyse potenzieller biotischer Effekte landwirtschaftlicher Betriebe

Summary

Organic farming depends on the promotion of biodiversity and the corresponding
functions. Almost no tools are known for the purpose of farm-specific information
explaining the influence of farm management on biodiversity. The paper describes a
pressure indicator oriented approach that allows estimating such effects. It has been
applied in 2 organic and 2 conventional farms where results were discussed. The
investigations made so far allow concluding that multiple-structured low-input systems
achieve better marks than specialized high-input systems. For further development
and validation additional studies are required. It is planned to test the indicator model
in numerous farms, in order to disclose bottlenecks and deficiencies.
