Conservation agriculture and organic farming are considered as promising sustainable agricultural system for producing food, while minimizing environmental impacts. Despite an increasing number of experimental data on organic conservation practices and various studies dealing with the adoption of conservation agriculture by farmers, none of those studies have specifically addressed conservation agriculture adoption under organic conditions in Europe. We carried out a survey with 159 farmers located in 10 European countries. These farmers had applied at least two of the following conservation practices: (i) no-tillage, (ii) reduced tillage and (iii) green manures. Each farmer assessed socio-economic, agronomic and environmental motivations and problems for... |

The nitrogen supply can be a yield-limiting factor in organic farming, especially when reduced tillage is applied. An organic field experiment was conducted from 2007 to 2013 to analyse the potential of the nitrogen supply through the efficient use of green manure crops in different tillage systems. Three farming systems were compared: a stubble cleaner system (SC) and a plough system (PL), both in a cereal-based crop rotation, and another plough system in a crop rotation that included alfalfa grass ley (PLALF). In the fifth year of the experiment, the experimental design was extended into a split plot design, and seven green manure treatments (Lolium perenne, Phacelia tanacetifolia, Sinapis alba, a mixture of Sinapis alba and Trifolium resupinatum,... |

Das Ziel des Beitrags ist die Bestimmung der N-Aufnahme unterschiedlicher legumer und nicht-legumer Gründüngungsarten sowie deren Wirkung auf die N-Verfügbarkeit zur Hauptfrucht Hafer, der in verschiedenen Bodenbearbeitungssystemen nach der Gründüngung angebaut wurde. Besonders hohe und von den anderen Gründüngungsarten signifikant verschiedene N-Werte fanden sich im Aufwuchs von Vicia sativa. V. sativa war auch die Gründüngungsart, die zu den höchsten Nmin-Werten im Frühjahr in allen Bodenbearbeitungssystemen führte. Auch die Bodenbearbeitung hatte einen Effekt auf die N-Verfügbarkeit: nach Pflügen war sie tendenziell höher als nach Bearbeitung mit dem Grubber und signifikant höher als nach Mulch- bzw. Direktsaat. |

Zwischenfrüchte spielen in ökologischen Anbausystemen mit reduzierter Bodenbearbeitung eine wesentliche Rolle. In dieser Übersichtsarbeit werden Ergebnisse aus einer ausführlichen Literaturrecherche hinsichtlich des N-Lieferungs- und Beikrautunterdrückungspotenzials von Zwischenfrüchten dargestellt. Die N-Aufnahme- und Biomasseertragsdaten verschiedener Zwischenfruchtarten und -artenmischungen werden tabellarisch wiedergegeben. Sie unterliegen – auch innerhalb einer Art – einer großen Spannbreite. Die N-Aufnahme ist dabei weitgehend – auch artübergreifend – vom Biomasseertrag abhängig. Gründe für ein gutes N-Aufnahmevermögen werden diskutiert. Die Steuerung der Mineralisierung durch die Wahl des Einarbeitungszeitpunkts wird erörtert. Mechanismen der... |

If farmers want to use reduced tillage in organic agriculture, they often face great challenges in weed control. One goal of the European research project TILMAN ORG (www.tilman-org.net) was to develop a more efficient weed management and increased biodiversity through improved use of green manures in different systems of reduced tillage. In a repeated one year trial on the research farm of University of Kassel the effects of different green manure species and different tillage systems on weed cover, density and biomass as well as yield of a subsequent main crop were examined. Sinapis alba, Trifolium resupinatum and Vicia sativa were tested as green manure species. Bare fallow served as control. After the green manures the main crop oat was sown in four... |

The interest of organic farmers for adopting conservation agriculture practices is currently growing. But, there are few technical and scientific references available for organic farmers when they start applying conservation agriculture practices. The main objectives of this study are (1) to explore the diversity of crop management practices using conservation agriculture methods among European farmers, and (2) to identify main farmers’ strategies. We carried out a survey of 159 farmers located in 10 European countries with a questionnaire with closed-ended questions. Data were analysis with a multi factor analysis followed by clustering to identify groups of farmers that share the same type of spring and winter crop managements. Organic farmers in Europe,... |

Field trials on reduced soil tillage under organic farming conditions across Europe were used to compare the soil quality changes over time. Soil organic carbon fractions, soil carbon stocks and microbial community structure were analysed. Most severe differences between plough and reduced tillage were found in the top ten cm of the soil profile. Differences became less or not significant in deeper layers. Analyses are still ongoing and will only be ready to be presented at the conference. |

Reduced tillage is increasingly promoted to improve sustainability and productivity of agricultural systems. Nonetheless, adoption of reduced tillage by organic farmers has been slow due to concerns about nutrient supply, soil structure, and weeds that may limit yields. Here, we compiled the results from both published and unpublished research comparing deep or shallow inversion tillage, with various categories of reduced tillage under organic management. Shallow refers to less than 25 cm. We found that (1) division of reduced tillage practices into different classes with varying degrees of intensity allowed us to assess the trade-offs between reductions in tillage intensity, crop yields, weed incidence, and soil C stocks. (2) Reducing tillage intensity in... |

Methoden der reduzierten Bodenbearbeitung wie nicht-wendende Verfahren oder eine nur oberflächliche Bearbeitung des Bodens gelten als umweltfreundliche Alternativen zum herkömmlichen Pflügen. Sie haben das Potenzial, die positiven Leistungen ökologischer Anbausysteme zu verstärken, wenn sie an die spezifischen Bedingungen des Ökologischen Landbaus angepasst werden. Auf dem Lehr- und Versuchsbetrieb der Universität Kassel, der Hessischen Staatsdomäne Frankenhausen, wurde ein wiederholter einjähriger Versuch angelegt. Dabei wurden drei verschiedene Zwischenfruchtarten mit unterschiedlicher Bodenbearbeitungsintensität eingearbeitet. Darauf folgte der Anbau von Hafer. Untersuchungen zur N-Lieferung und zum Beikrautunterdrückungspotenzial der Zwischenfrüchte... |

The interest of organic farmers in adopting conservation agriculture principles, including minimal soil disturbance, permanent soil cover and crop rotation has been growing since the early 2000s. However, currently there is no network for organic farmers practicing conservation agriculture, and a lack of knowledge on how organic farmers implement conservation agriculture in practice. Consequently, few technical references are available for organic farmers when they start applying conservation agriculture practices, in particular on controlling weeds without the use of herbicides. The main objectives of this study were: (1) to explore the diversity of conservation agriculture techniques (i.e., reduced tillage, no-tillage and green manures) practiced among... |

Reduced tillage and green manures may be capable to further improve organic crop production systems. However, it is presumed that under organic farming conditions a lower intensity of soil tillage may reduce nitrogen (N) availability and increase weed pressure. A combination of reduced tillage with an appropriate green manure species could answer these problems. The results of a repeated one year trial on the research farm of University of Kassel, regarding the effects of three different green manure species (Sinapis alba, Trifolium resupinatum and Vicia sativa) and conventional (plough) vs. reduced tillage (2012 chisel, 2013 disc harrow) on N availability in spring and on the yield of main crop oat are the topic of this paper. In both years, in the... |

One of the objectives of the TILMAN-ORG Project is to improve weed management under conservation agriculture (reduced tillage and/or cover crops) in organic arable systems. The shift from ploughing to conservation agriculture should not only maintain crop yield but possibly improve weed community diversity. This paper summarises the results on (1) weed abundance, (2) weed diversity and (3) crop yield obtained in the first year of the project (2012) in 13 trials scattered across Europe. |

We carried out a survey about motivations and problems of 159 farmers located in 10 European countries with a questionnaire with closed-ended questions.
