There is an increased interest in Europe to develop organic farming systems with reduced tillage intensity. Besides technical and agronomical aspects, the profitability of these systems has to be viable for farmers to achieve a successful implementation in practice. A long-term trial was set up in 2009 at the research station Agroscope Reckenholz-Tänikon (ART) to compare conventional and organic farming systems with and without ploughing including a full cost calculation to assess the profitability of the different systems. First results show that the highest benefit was obtained under organic cultivation under Swiss legislation. Moreover, production costs were reduced with the adoption of conservation tillage. |

Direct drilling has been studied by MTT Agrifood Research Finland since the 1980s, but conclusions here are mainly based on field trials on clay soils in 2000s. Differences in amount and quality of yield from ploughed and no-till soil vary between years, fields and species. Timing and implementation of drilling in no-till soil is especially challenging. Oat did grow and yield more reliably than other spring cetreals when direct drilled. The protein content of spring cereal grains was low in direct drilling. |

The introduction of cover crops (CC) in crop rotations is a key tool to control weed and ameliorate soil conditions in low input arable systems. In 1992 a long term experiment (LTE) was set up at Centre for Agri-environmental Research “E. Avanzi (CIRAA), University of Pisa to determine the combined effect of tillage intensity, nitrogen fertilization levels and CC types on soil quality, crop yield and weed communities. The LTE is based on 4-year crop rotation (maize, durum wheat, sunflower, durum wheat) with cover crops grown twice, in between wheat and summer crops. Two tillage systems were compared: i) a conventional system (CS), with annual ploughing (30 cm depth); ii) a low input system (LIS), with chiseling (30 cm depth) for summer crops and no... |

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,... |

The soil between the tracks remains undisturbed. Its structure is crumbly and thus optimal for plant growth. Practical information • Controlled traffic farming is a system approach that has an effect on the entire farm. Good preparation is necessary, e.g., by getting informed from colleagues who already use CTF. • Depending on the farm and the available mechanization (esp. working width), there are several ways to work with tramlines. Examples are bed-cultivation with a 1.5 to 3.2 m track width or a default track-width (often 1.5 m) with standardized, often wide machines (3 to 9 m in width). • Use standard equipment and standard working widths that are used on your own and on neighbouring operations (e.g. farmer-colleagues, agricultural contractors)... |

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. |

Organic farming practices aim to maximise the delivery of ecosystem services in the agricultural landscape. However, in order to maintain optimal crop productivity the mouldboard plough is often used to control weeds and this can have negative effects on a range of soil parameters, thereby jeopardizing delivery of these services. Reduced tillage (RT) can be beneficial to soils and could improve both the efficiency of production and the delivery of ecosystem services on organic farms. However, abandoning the plough on organic farms is challenging due to impaired weed control. Here we report on a two year trial where an RT system with the Ecodyn, with duck feet shares operating at a depth of 7.6 cm in combination with seed drilling, was compared with... |

Soil conservation practices are growingly used with different aims such as reducing fuel consumption and preserving soil organic carbon (SOC). Among others, reduced tillage (RT) often replaces conventional tillage (CT). However, the compared impact of these practices on soil quality remains a matter of controversy. Moreover, the various changes expected are rarely considered all together though they are known to interact. This study aimed at characterizing together the changes in SOC, microbial activity, and a large set of physical properties when comparing RT and CT performed on a clayey soil. Shrinkage analysis allowed to characterize simultaneously the soil pore systems, their volume, air and water content, the hydro-structural stability, and the... |

Turkey is the major producer and exporter of seedless raisins in the world. The largest area under organic raisin is located in Manisa (2655 ha) then İzmir (580 ha) in the Aegean Region and almost all the grapes are dried and exported to European countries in particular. Organic raisin production constitutes 1.35% of the total raisin production of Turkey. The research was carried out in Alaşehir-Yeşilyurt Enterprise of Viticulture Research Station from 2006 to 2007. The research was established in a 15 year-old ‘Sultani Çekirdeksiz’ vineyard under irrigable soil conditions in organic parcel. Three different tillage methods: conventional tillage, mulch tillage, and reduced tillage were applied on the trial parcels. The research was carried out as randomized... |

Organic and conventional cropping systems differ in the nature and amounts of nitrogen (N) inputs, which may affect efficiency and sustainability of N use. In the DOK (bio-Dynamic, bio-Organic, Konventionell) field experiment, organic and conventional cropping systems have been compared since 1978 at two fertilization levels. Nitrogen inputs via manure and/or mineral fertilizers, and N exports from plots with harvested products have throughout been recorded. For all treatments, N outputs with harvests have exceeded the inputs with fertilizers. Over the past years, symbiotic N2 fixation by soybean and clover grown in the trial has additionally been assessed, indicating average annual inputs of about 100 kg ha-1 yr-1 of N fixed from the atmosphere.

This study investigated the lasting impact of reduced and conservation tillage, namely two-layer ploughing (LP) and layer-cultivating (LC) on soil ecological properties (physical, chemical, microbiological) in an organic farming system relative to ploughing (P). As a major trend, the amounts of soil organic C, microbial biomass –C and –N, Cmic to Corg ratio, and microbial activity increased in 0-15cm depth in the order P –LP – LC while they decreased in 15-25cm depth in the same order, both in green fallow and winter rye plots. For example, in 0-15 cm depth soil microbial biomass –C concentration was significantly 21 % (LP) and 30 % (LC) greater in green fallow plots or 15 % to 23 % greater in winter rye plots than in P. This was highly correlated with an... |

In a long-term field trial recently launched (2002-2011), located in Frick (878 mm mean annual precipitation) near Basle, Switzerland, the effect of reduced tillage on soil fertility indicators and crop yield was studied in a heavy soil (45% clay) in a crop rotation under organic farming conditions. We present the results of soil analyses after three cropping years (2002-2005). Soil organic carbon (Corg) increased over that period by 7.4% (+1.5 g Corg kg-1 soil) in the 0-10 cm soil layer in the reduced tillage plots, while it remained constant in the ploughed plots. Soil microbial carbon (Cmic) and dehydrogenase activity (DHA, TTC-reduction) were 28% higher in reduced-tillage plots in this soil layer. Biological soil quality as calculated by Cmic to Corg... |

Bodenlebewesen gelten als die Architekten von Bodenqualität und steuern alle wichtigen Umsetzungsprozesse im Boden. Sie stehen damit in unmittelbarem Zusammenhang zu wichtigen Ökosystemdienstleistungen von Böden wie Kohlenstoffspeicher, Pufferwirkung und Schadstoffbau, Pflanzenertrag und -qualität und Reduktion von Spurengasemissionen. Darüber hinaus gelten Böden auch als wichtige Indikatoren für Bodenqualität, da sie auf Grund ihr er meist schnellen Generationszeiten Änderungen schon sehr frühzeitig anzeigen können. Im Rahmen dieses Projektes soll daher der Einfluss von reduzierter Bodenbearbeitung und Gründünger auf die Bodenqualität untersucht werden an Hand von verschiedenen Langzeitversuchen an unterschiedlichen Standorten in Europa.
