Bodenfruchtbarkeit und biologische Vielfalt im ökologischen Landbau Organic Eprints
Mäder, Dr. Paul; Fliessbach, Dr. Andreas; Dubois, Dr. David; Gunst, Lucie; Fried, Dr. Padruot; Niggli, Dr. Urs.
Um die Effektivität landwirtschaftlicher Anbausysteme zu beurteilen, bedarf es eines Verständnisses der Agrarökosysteme. Eine 21-jährige Studie ergab 20 Prozent geringere Erträge bei ökologischen Anbausystemen gegenüber konventionellen, obgleich der Einsatz von Düngemitteln und Energie um 34 bis 53 Prozent und der von Pestiziden um 97 Prozent geringer war. Wahrscheinlich führen die erhöhte Bodenfruchtbarkeit und die größere biologische Vielfalt in den ökologischen Versuchsparzellen dazu, dass diese Systeme weniger auf Zufuhr von außen angewiesen sind.

DOK-Versuch: Nährstoffversorgung in Winterweizen – Wo wird es eng? Organic Eprints
Gunst, Lucie; Richner, Walter; Mäder, Paul; Mayer, Jochen.
Das Ziel des seit 1978 durchgeführten DOK-Systemversuchs in Therwil BL ist der Vergleich zwischen einem biologisch-dynamischen (D), einem organisch-biologischen (O), einem konventionellen (K; organisch-mineralische Düngung) und einem konventionell-mineralischen (M; ausschliesslich mineralische Düngung) Anbausystem im Hinblick auf nachhaltigen Pflanzenbau und Bodenfruchtbarkeit. Der Versuch verfügt über zwei Düngungsniveaus (Tab. 1) und erlaubt die Untersuchung der Einflüsse unterschiedlicher Nährstoffversorgung auf die Ertragsbildung und Aussagen zu Limitierungen einzelner Pflanzennährstoffe.

Einfluss der Bewirtschaftungsform, der Vorfrucht und der Düngung auf den Befall von Winterweizenkörnern mit Pilzkrankheiten im DOK-Versuch Organic Eprints
Gunst, Lucie; Krebs, Heinz; Dubois, D.; Forrer, H.-R..
In the DOK long-term field trial in Switzerland comparing bio-dynamic, bio-organic, and conventional farming systems, the occurrence of Fusarium species and Microdochium nivale on grains of wheat was investigated from 1997 to 2003. Although no differences between the farming systems were found, the previous crop, the fertilisation level, and the year significantly influenced the disease incidence. In 2003, the effect of the pre-crops potatoes versus silage-maize on fusaria was compared. As expected, the incidence of fusaria was significantly higher after maize compared with potatoes. However, the main responsible species was not F. graminearum but F. poae. This species is known for the production of hazardous toxins. A greater input of fertiliser resulted...

Ertrag von Mais und Sojabohnen im biologischen und konventionellen Anbausystem des DOK-Versuchs Organic Eprints
Mäder, Paul; Fliessbach, Andreas; Niggli, Urs; Gunst, Lucie; Mayer, Jochen.
Sustainable food and feed production is becoming a major issue with regard to the growing world’s population and the scarcity of non-renewable resources such as energy and fertilizers. Long-term trials offer the unique opportunity to assess the performance of cropping systems over decades, providing meaningful data. While many studies have proven, that organic farming generally increases soil fertility and biodiversity, long-term productivity of organic systems is questioned. Here we show that across all crops of a seven year rotation, yields of the organic system were approx. 81% of those of the conventional system in the fifth rotation period of the DOK trial (2006-2012), but with much lower input of nutrients and pesticides. Two major food and feed...

Life Cycle Assessment of Conventional and Organic Farming in the DOC trial Organic Eprints
Nemecek, Thomas; Dubois, David; Gunst, Lucie; Gaillard, Gérard.
The environmental impacts of the conventional and organic farming systems practised in the DOC trial (organic-dynamic, organic and conventional farming) have been assessed by the SALCA life cycle assessment method. Both organic farming systems were more favourable for the environment in all investigated impacts per area unit. When analysed per product unit, clear advantages of organic farming were found for ecotoxicity and the use of mineral resources, while energy use and eutrophication were similar to conventional farming. Reducing fertilisation by 50% led to lower or equal environmental impacts for all systems, depending on the impact category and the functional unit. The analysis of single crops revealed large differences that are partly...

Long-term organic farming fosters below and aboveground biota: Implications for soil quality, biological control and productivity Organic Eprints
Birkhofer, Klaus; Bezemer, TM; Bloem, J; Bonkowski , M; Christensen, S.; Dubois, David; Ekelund , F; Fließbach, Andreas; Gunst, Lucie; Hedlund , K; Mäder, Paul; Mikola , J; Robin , C; Setälä, Heikki; Tatin-Froux , F; Van der Putten , WH; Scheu, Stefan.
Organic farming may contribute substantially to future agricultural production worldwide by improving soil quality and pest control, thereby reducing environmental impacts of conventional farming. We investigated in a comprehensive way soil chemical, as well as below and aboveground biological parameters of two organic and two conventional wheat farming systems that primarily differed in fertilization and weed management strategies. Contrast analyses identified management related differences between “herbicide-free” bioorganic (BIOORG) and biodynamic (BIODYN) systems and conventional systems with (CONFYM) or without manure (CONMIN) and herbicide application within a long-term agricultural experiment (DOK trial, Switzerland). Soil carbon content was...

Organic Farming and Energy Efficiency. FiBL response to the letter of Zoebl in Science Vol 298 Organic Eprints
Mäder, Paul; Fliessbach, Andreas; Dubois, David; Gunst, Lucie; Fried, Padrout; Niggli, Urs.
We agree with Zoebl that alternative farming systems deserve more attention in order to develop healthy production systems. In fact, the environmental advantages of organic farming in comparison with intensive conventional production methods have been shown in many cases (1). In our study, we showed a better protection of soil fertility in organic systems compared with conventional systems.

Organic farming enhances soil fertility and biodiversity Organic Eprints
Fliessbach, Andreas; Mäder, Paul; Dubois, David; Gunst, Lucie.
The DOK-long term trial - unique in his conception - compares the consequences of bio-dynamic, bio-organic and conventional farming systems in a randomised plot trial. The field trial was started in 1978. In the beginning the main goals were agronomic: yield and product quality. In the last decade, therefor research has focused on processes in the soil and the long-term effects of organic farming practice on the environment.The database of agronomic results of more than twenty years has stimulatad the discussion about farming systems and has contributed significantly to the general acceptance of organic farming.

Performance und Ertragsbildung von Winterweizen im DOK-Versuch Organic Eprints
Mayer, Jochen; Mäder, Paul; Gunst, Lucie.
Wheat yield performance and bread baking quality was investigated in the DOK long term experiment in Switzerland. Yield and crude protein differed between biological and conventional systems but not between bio-organic and bio-dynamic systems. The same observations were made for yield components and baking quality parameters. Potatoes as preceding crops compared to maize performed much better than increased manure application in biological systems.

Phosphor- und Kalium-Bilanzen über 35 Jahre DOK-Versuch & geschätzte K-Nachlieferungsraten auf einem Lössboden Organic Eprints
Jarosch, KA.; Gunst, Lucie; Dubois, David; Mäder, Paul; Mayer, Jochen.
We calculated a phosphorus (P) and potassium (K) balance for the DOK-trial (Therwil, Switzerland) for a 35-years cropping period. In the DOK-trial, three cropping systems (D: biodynamic, O: bioorganic and K: conventional) are maintained on both a full (2) and a halved (1) fertilization level. Additionally, a treatment with no fertilization (N) and mineral fertilization (M; since 1985) are included. Balance inputs included fertilization, deposition, nutrients inputs by seeds, while in the outputs removal of nutrients by harvested plant material and leaching was considered. For P, the balance was positive for treatment M and treatment O2, but negative for the other treatments. The K-balance was positive only for treatment M, while treatments D2, O2 and K2...

Soil Fertility and Biodiversity in Organic Farming Organic Eprints
Mäder, Paul; Fliessbach, Andreas; Dubois, David; Gunst, Lucie; Fried, Padruot; Niggli, Urs.
An understanding of agroecosystems is a 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.

Soil microbial community structure and organic matter transformation processes in organic and integrated farming systems Organic Eprints
Fliessbach, Andreas; Dubois, David; Esperschütz, Jürgen; Gunst, Lucie; Mäder, Paul; Oberholzer, Hansruedi; Schloter, Michael; Gattinger, Andreas.
The DOK long-term field trial in Switzerland started in 1978 (Mäder et al., 2002). Biodynamic (BIODYN), bioorganic (BIOORG) and integrated (CONFYM) farming systems with manure fertilization, an integrated system based on mineral fertilizer only (CONMIN) and an unfertilized control (NOFERT) were investigated for changes in soil organic matter and on the structure of the soil microbial communities. Soil organic matter (SOM) in the Ap-horizon (0-20 cm) was analysed from the beginning of the DOK field trial in 1978. Roughly 20% of the initial SOM was lost when no manure was applied for 21 years as in the CONMIN and the NOFERT system, whereas SOM increased slightly by 4% in the BIODYN system that makes use of composted farmyard manure, corresponding to 1.4...

Soil organic matter and biological soil quality indicators after 21 years of organic and conventional farming Organic Eprints
Fliessbach, Andreas; Oberholzer, Hans-Rudolf; Gunst, Lucie; Paul, Mäder.
Organic farming systems often comprise crops and livestock, recycle farmyard manure for fertilization, and preventive or biocontrol measures are used for plant protection. We determined indicators for soil quality changes in the DOK long-term comparison trial that was initiated in 1978. This replicated field trial comprises organic and integrated (conventional) farming systems that are typical for Swiss agriculture. Livestock based bio-organic (BIOORG), bio-dynamic (BIODYN) and integrated farming systems (CONFYM) were compared at reduced and normal fertilization intensity (0.7 and 1.4 livestock units, LU) in a 7 year crop rotation. A stockless integrated system is fertilized with mineral fertilizers exclusively (CONMIN) and one control treatment remained...
