| No-tillage (NT) and reduced tillage (RT) systems are well-known management tools for reducing soil erosion and improving soil fertility. NT and RT may improve the environmental and economic performance of organic farming, but they are still not common practice among organic farmers. This paper presents the effects of tillage [RT versus conventional tillage (CT)], fertilization (slurry versus manure compost) and biodynamic preparations (with versus without) on soil fertility indicators such as soil organic carbon (Corg), microbial biomass and microbial activity, soil nutrients and nutrient budgets in an organic farming system during the first six-year crop rotation period of a long-term experiment on a clayey soil in a temperate climate. RT caused... |

| Effective microorganisms® (EM) is a microbial inoculant promoted to stimulate plant growth and soil fertility in agriculture. In our study we investigated the effects of EM on crop yields and soil microbial parameters in a 4-year field experiment under organic management (2003–2006) in Zurich, Switzerland. Treatments of the EM preparations (i) the spraying agent EMA, (ii) EMA with the EM enriched organic substrate Bokashi and (iii) EMA with Bokashi and farmyard manure were applied in each year. As controls to treatments (i)–(iii) the same treatments were included with sterilised EM preparations and a control without EM application. Crop yields in each year and the soil microbiological parameters soil respiration, microbial biomass (SIR, CFE), dehydrogenase... |

| Der Einsatz von Pflanzenschutzmitteln (PSM) in der Landwirtschaft ist mit Risiken für die Anwender, die Umwelt und die Konsumenten verbunden. Das Risiko hängt von der Menge, der Toxizität und dem Umweltverhalten der Wirkstoffe in Pflanzenschutzmitteln und ihrer Formulierungen ab. In vielen Ländern werden daher die Pflanzenschutzmittelaufwendungen aufgezeichnet, und mittels mehr oder weniger komplexer Modelle die dadurch bedingten Risken abgeschätzt. In der Europäischen Gemeinschaft soll dieses Vorgehen im Rahmen der gemeinsamen Agrarpolitik harmonisiert werden. In der Schweiz wird der Verkauf und Einsatz von Pflanzenschutzmiteln in der Landwirtschaft seit einigen Jahrzehnten aufgezeichnet. Die Schweizerische Gesellschaft der Chemischen Industrie (SGCI) hat... |

| P. fluorescens is used in agriculture and horticulture as a plant growth promoting rhizobacterium. It colonizes root surfaces effectively and excretes compounds that are influencing plant nutrient uptake and plant health. Soils with different initial biological fertility were analysed 18 and 60 days after inoculating the freshly sown wheat plants with a suspension of a rifampicine tolerant strain of P. fluorescens CHA0, in order to evaluate its survival and lasting effect on soil microbial biomass. P. fluorescens had a lasting effect in soils with low initial biomass, but no lasting effects were found in biologically active soils. |

| Die Landwirtschaft trägt weltweit mit 12–32 Prozent zum Klimawandel bei. Hauptquellen sind der Methanausstoss der Wiederkäuer, der CO2-Verbrauch für die Herstellung von Düngern und Pestiziden, die Abholzung von Wäldern für den Ackerbau und Weideflächen sowie die Bodenerosion. Auch der Einsatz des Pflugs verbraucht viel Energie, verstärkt den Abbau von Humus und belastet somit das Klima. Gemäss bisherigen Untersuchungen benötigt die biologische Landwirtschaft schon heute mit den gängigen Methoden weniger Energie als die konventionelle Bewirtschaftung. Im DOK-Versuch zum Beispiel verbrauchen die Bioverfahren 20 Prozent weniger Energie pro Ertragseinheit. Dies macht den Biolandbau zwar klimafreundlicher, aber noch nicht klimaneutral. Durch die Anwendung... |

| Genetically modified (GM) maize containing genes from the soil bacterium Bacillus thuringiensis (Bt) was cultivated on 29% of the total maize production area worldwide in 2009. Most studies to date compare Bt- maize varieties with their near isogenic lines; however, there is little information on the variability of conventional maize breeding lines and how the effects of Bt varieties are ranked within. In our study on the potential risks of Bt- maize varieties, we analyzed tissue quality and compared the effects of ten conventional and GM maize varieties on soil microbiological properties in a replicated climate chamber experiment. All maize varieties were cultivated twice in the same soil microcosm. Shoot yields and soluble C in leaf tissue of Bt... |

| Goklany stated that 20 % lower crop yields in organic farming would require 25 % more land use to produce the same amount of crop biomass, offsetting some of the advantages of organic agriculture with respect to biological diversity, inputs, and soil erosion, and that the experimental yields are not typical. Furthermore, he indicates that organic farming might not be sufficient to feed the world. |

| The impact of soil type, long-term soil management, and short-term fertility input strategies on the suppressiveness of soils against soil-borne (Ocimum basilicum – Rhizoctonia solani, Lepidium sativum – Pythium ultimum) as well as air-borne (Lycopersicon esculentum – Phytophthora infestans, Arabidopsis thaliana – Hyaloperonospora parasitica) diseases was studied. Soils from field trials established in five European sites with contrasting pedo-climatic conditions were examined. Sites included (i) a long-term management field trial comparing organic and conventional farming systems (DOK-trial, Therwil, Switzerland) (ii) a short-term fertility input field trial comparing mineral and organic matter fertilisation regimes (Bonn (BON), Germany) (iii) two... |

| The aim of this study was to evaluate the interaction between yield levels of nonleguminous crops and soil organic matter (SOM) under the specific conditions of organic and conventional farming, respectively, and to identify implications for SOM management in arable farming considering the farming system (organic vs. conventional). For that purpose, correlations between yield levels of nonlegume crops and actual SOM level (Corg, Nt, Chwe, Nhwe) as well as SOM-level development were examined including primary data from selected treatments of seven long-term field experiments in Germany and Switzerland. Yield levels of nonlegume crops were positively correlated with SOM levels, but the correlation was significant only under conditions of organic farming, and... |

| Mit der Umstellung des Gutes Rheinau von konventionell integrierter Bewirtschaftung auf bio-dynamische Wirtschaftsweise im Jahre 1998 wurde ein Monitoring der Bodenfruchtbarkeit begonnen, dass die biologische Veränderung im Boden während der Umstellungsphase dokumentieren sollte. Die ersten Bodenproben wurden 1999 auf drei Ackerschlägen und einer permanenten Naturwiese gezogen und dann wurden im Jahr 2002, 2005 und 2010 auf den in 1999 definierten Teilflächen je Schlag weitere Bodenproben entnommen. Neben mikrobiologischen Bodenparametern (mikrobielle Biomasse, Basalatmung, Dehydrogenaseaktivität) wurden die Regenwurmpopulationen und auch chemische Bodenparameter und lösliche und nachlieferbare Fraktionen wichtiger Nährstoffe ermittelt. Ausserdem erfolgte... |

| Pesticides applied to potatoes in Swiss integrated farming were evaluated with respect to their cumulative effects on soil microorganisms in a study performed under controlled conditions. Potatoes were treated with a series of herbicides, fungicides and insecticides and were finally defoliated either by hand in the untreated control or with the total herbicides Basta (active ingredient glufosinate) or Super Kabrol (active ingredient dinoseb). Twenty-one and 135 days after the last pesticide application soil samples were collected and analysed for microbial biomass, activity and community level substrate utilisation (CLSU). In the short-term, cumulative pesticide side-effects on microbial biomass and microbial activities averaged 19% for the spraying... |

| In their letter, Leifeld et al. (1) argue that our metaanalysis to identify differences in soil organic carbon (SOC) between organic (OF) and nonorganic farming [conventional farming (CF)] (2) selected CF systems that were nonrepresentative. This was not the case. We included data from all available pairwise field comparisons between OF and CF identified in the literature. The observed difference in external carbon (C) inputs between OF and CF did not result from a bias in the selection of studies/treatments but was attributable to the fact that the field comparisons we analyzed (2) were not from fertilization experiments but from pairwise farming system comparisons where the design and the underlying treatments reflected the current farming practices in... |

| Zvyšování půdní úrodnosti bylo pro průkopníky ekologického zemědělství základem veškerého jejich úsilí. Přesto zachování úrodné půdy mnohdy nebyla věnována dostatečná pozornost. Ekologické zemědělství je však na přirozené půdní úrodnosti závislé. Oslabená a poškozená půda nám nemůže poskytnout to, co od ní očekáváme. Udržet úrodnost půdy vyžaduje velkou péči. Předkládaná brožura ukazuje půdní úrodnost z různých úhlů pohledu. Naším záměrem však nebylo vytvořit obecně platný „návod k použití“. Informace mají být mnohem spíše podnětem k tomu, aby se o vztahu člověka k půdě smýšlelo jinak a aby se tento vztah utvářel ve prospěch budoucnosti. |

| When residues and organic fertilizers are not incorporated into the soil, they build a top soil layer that is enriched in soil organic matter. This is leading to a soil layer with increased biological activity, while the soil layers below, receive less inputs in form of residues or manures and show a reduction in soil organic matter and biological activity. Soils from a replicated field trial and two on-farm trials were analysed for biological soil quality 6 years after the implementation of reduced tillage (RT) as compared to plough. Whilst crop yields were slightly lower with RT, weed cover was increasing, but not to a level that would compromise yields. Soils under RT accumulated soil organic matter in the tilled top layer of 0-10 cm, while in the... |

| Die angewendeten Methoden erwiesen sich als geeignet, um die mikrobiellen Gemeinschaften und deren physiologische Eigenschaften in den Böden der Anbausysteme des DOK-Versuches zu untersuchen. Sämtliche Parameter konnten Veränderungen der physiologischen Eigenschaften und taxonomischen Zusammensetzung beschreiben, die hauptsächlich auf die unterschiedlichen Anbausysteme und Kulturen zurückzuführen sind. Es stellte sich zudem heraus, dass die Veränderungen besonders durch die Art der Düngung (organisch vs. mineralisch) hervorgerufen wurden. Die Untersuchung hat gezeigt, dass eine verknüpfende Betrachtung der Ergebnisse der hier angeführten Analysemethoden sinnvoll ist, um zukünftig verbesserte Aussagen über Bodenqualität und -fruchtbarkeit in... |

| Soils are one of the largest organic carbon pools and changes in the carbon release from soils has considerable impact on the composition of atmospheric CO2. Alongside the accelerated carbon release from soils by anthro-pogenic warming (Crowther et al., 2016), agricultural use strongly affects soil organic carbon (SOC) (Johnstonet al., 2009). Conversion from conventional to organic farming has been suggested a valuable contribution to sequester SOC providing a great mitigation potential within agricultural practices (Smith et al., 2008).Here we present SOC contents and 14C activity under two different farming practices in the long-termagricultural DOK trial at Therwil, Switzerland (Mäder et al., 2002). In this long-lasting agricultural experiment, we... |
