| To promote conservation tillage in organic farming systems, weed control and ley removal within arable-ley rotations need to be optimized. A long-term field trial was thus established in Frick, Switzerland in 2002 on a clayey soil and with a mean precipitation of 1000 mm⁄ year. The tillage experiment distinguished between conventional tillage with mouldboard ploughing (CT, 15 cm depth) and reduced tillage (RT), including a chisel plough (15 cm) and a stubble cleaner (5 cm). Results of a 2-year grass-clover ley (2006 ⁄ 2007) and silage maize (2008) are presented. Due to dry conditions, mean grass-clover yields were 25% higher in RT than in CT, indicating better water retention of RT soils. Clover cover and mineral contents of the fodder mixture were also... |

| Ziel dieses Projektes war es, eine Charakterisierung des seuchenhygienischen Zustandes von flüssigem Gärgut aus Schweizer Vergärungsanlagen in Relation zu den Ausgangsmaterialien und zu den angewandten Techniken der Vorbehandlung, der anaeroben Vergärung und der Nachbehandlung durchzuführen. Drei Probenahmekampagnen wurden durchgeführt: im Winter 2012-2013, im Frühling 2013 und im Sommer 2013. Dabei wurden repräsentative thermophile und mesophile Vergärungsanlagen detailliert untersucht. Die verschiedenen Ausgangsmaterialien sowie Gärgut in verschiedenen Prozessstufen wurden auf die Leitkeime Salmonellen, Coliforme, E. coli, Enterokokken und teilweise Campylobacter untersucht. Die Inputmaterialien mit dem grössten Erregerbesatz sind Grüngut und... |

| A yearly amount of 9.3x106t compost and digestate derived from separately collected organic waste is produced in the 25 European Union member states. The improvement of soil properties is a major benefit of compost application. However, little is known about the occurrence of organic pollutants in compost. In order to estimate the potential of Swiss composts and digestates to influence soil fertility and plant health, one hundred products representative for the different composting systems and qualities available on the Swiss market were analyzed in two research projects. In the first study, polycyclic aromatic hydrocarbons (PAHs), ortho substituted and dioxin-like polychlorinated biphenyls (PCBs, DL PCBs), polychlorinated dibenzo-p-dioxins and... |

| Soil microorganisms guarantee numerous soil functions, such as nutrient cycling, soil structure formation and the regulation of soil pathogens. Restoring soil fertility and increasing stability of soil is an urgent call to farmers. Soils also serve as a habitat for an almost uncountable diversity of soil microbes, which often is closely linked to the above ground one. Active, well-structured soils guarantee sustainable yields and safeguard natural resources simultaneously. Farming systems as a whole, but also individual practices such as tillage, the use of organic manures and crop rotations have a strong influence on soil microbial activities and biodiversity. Long-term trials are ideal bases to identify effects of agricultural management on the soil... |

| Most varieties have been selected under high input conditions, including seed treatment, herbicide applications, as well as optimal levels of fast releasing fertilizers. Under organic farming nutrient release is dependent on the temperature and biological activity of the soil and its interaction with the declining residues from previous crops and applied quantity of farmyard manure. As a consequence it is not always possible to match nutrient release with crop demand over time. This effect is even more severe under conservation tillage. To promote conservation tillage in organic farming, it is necessary to identify cultivars that show high nutrient use efficiency (NUE) under these conditions. While there is substantial evidence that breeding for low N... |

| 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. |

| In a recently started long-term field trial (2002-2011), located in Frick (1000 mm mean annual precipi-tation) near Basle (Switzerland), the effect of reduced tillage on crop yield, weed infestation, and oc-currence of toxigenic fusaria was studied on a heavy soil (45% clay) in a crop rotation under organic farming conditions. Here, we present results of the first two experimental years (2003-2004), which are considered as the conversion period. Wheat yield was 16% higher (p < 0.001) in ploughed plots than in the plots with reduced tillage (chisel and rotary harrow). In the following year, sunflower yield was enhanced by 5% (p = 0.06) in reduced tilled plots. Reduced tilled plots manifested a higher weed infestation, in particular with Convolvulus... |

| Composts and digestates can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the composts. A currently important question is to know, if digestates differ from composts in these aspects. A Swiss project is concerned with the estimation of the potential of Swiss composts and digestates to influence soil fertility and plant health positively. For this, one hundred composts and digestates representative of the different composting systems and qualities available on the Swiss market were analyzed. The organic matter and nutrient content of the composts varied greatly between the composts and the digestates; the materials of origin were the major factor influencing these values. The... |

| Um den Einfluss von Kompost und Gärgut auf die Bodenfruchtbarkeit und auf das Pflanzenwachstum abschätzen zu können wurden hundert, für die Schweiz repräsentative, Proben untersucht. Die Gehalte an Nährstoffen und an Salz waren vom Ausgangsmaterialien abhängig. Die Gehalte an organischer Substanz sowie die Atmungs- und Enzymaktivitäten nahmen mit zunehmender Kompostreife ab. Bei einigen jungen Komposten konnten Stickstoffblockaden beobachtet werden. Der Nitratgehalt im Kompost erlaubt jedoch vorherzusagen, ob eine N-Immobilisierungsgefahr besteht oder nicht. Die Phytotoxizität der Komposte variierte auch bei den reiferen Produkten sehr stark. Dies weist auf die grosse Bedeutung der Rotteführung und der korrekten Lagerung der Produkte hin. Während die... |

| Reduced tillage may improve the environmental and economic performance of organic farming. Reducing the intensity of soil tillage decreases the energy consumption and the emission of carbon dioxide, and could increase carbon sequestration (Holland 2004). Reduced tillage also may improve water retention and reduce soil erosion (Berner et al 2008). One of the main drawbacks of the reduced tillage practices is the potential increase of weed infestation and changes in weed species composition, sometimes to the benefit of species which are more difficult to control, such as perennial and grass species (Peigné et al 2007; Teasdale et al 2007; Sans et al 2011). Organic farmers commonly keep weeds under control by ploughing and by post-emergence mechanical... |

| 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... |
