Soil Fertility and Biodiversity in Organic Farming

Paul Ma¬der, Andreas Fliebbach, David Dubois, Lucie Gunst, Padruot Fried, Urs Niggli

An understanding of agroecosystems is key to determining effective farming
systems. Here we report results from a 21-year study of agronomic and ecological
performance of biodynamic, bioorganic, and conventional farming systems
in Central Europe. We found crop yields to be 20% lower in the organic
systems, although input of fertilizer and energy was reduced by 34 to 53% and
pesticide input by 97%. Enhanced soil fertility and higher biodiversity found in
organic plots may render these systems less dependent on external inputs.
