Journal ArticleDOI
Soil Fertility and Biodiversity in Organic Farming
TL;DR: Results from a 21-year study of agronomic and ecological performance of biodynamic, bioorganic, and conventional farming systems in Central Europe found crop yields to be 20% lower in the organic systems, although input of fertilizer and energy was reduced.
Journal ArticleDOI
Impact of long-term conventional and organic farming on the diversity of arbuscular mycorrhizal fungi
Fritz Oehl,Ewald Sieverding,Paul Mäder,David Dubois,Kurt Ineichen,Thomas Boller,Andres Wiemken +6 more
TL;DR: The findings show that some AMF species present in natural ecosystems are maintained under organic farming but severely depressed under conventional Farming, indicating a potentially severe loss of ecosystem function under conventional farming.
Journal ArticleDOI
Wheat quality in organic and conventional farming: results of a 21 year field experiment
Paul Mäder,Diana Hahn,Diana Hahn,David Dubois,Lucie Gunst,Thomas Alföldi,Hans Bergmann,Michael Oehme,Renato Amadò,Hanna Schneider,Ursula Graf,Alberta Velimirov,Andreas Fließbach,Urs Niggli +13 more
TL;DR: In this article, the results of a study on the quality of wheat (Triticum aestivum L.) grown in a 21-year agrosystem comparison between organic and conventional farming in central Europe are reported.
Journal ArticleDOI
Phosphorus budget and phosphorus availability in soils under organic and conventional farming
Fritz Oehl,Astrid Oberson,H.U. Tagmann,J. M. Besson,David Dubois,Paul Mäder,H.-R. Roth,Emmanuel Frossard +7 more
TL;DR: In this paper, a long-term field trial comparing a non-fertilised control (NON), two conventionally cultivated treatments (MIN, CON), and two organically-cultivated treatments (ORG, DYN).
Journal ArticleDOI
Nitrogen fertilizer value of cattle manure applied on soils originating from organic and conventional farming systems
TL;DR: In this paper, it was shown that on a long-term organically managed soil (ORG) characterized by higher soil microbial activity, a greater portion of N applied as cattle manure is mineralized and taken up by plants than on a conventionally managed soil that had received exclusively mineral fertilizers (MIN).
