| 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... |

| Problemstellung/Ziele: Die Zusammensetzung mikrobieller Gemeinschaften und deren Funktionen im Boden kann mit Hilfe moderner Techniken beschrieben werden. Diese beruhen u.a. auf der Untersuchung der genetischen Eigenschaften mittels DNA-Analysen, molekularen Markern der Zellmembran oder physiologischer Eigenschaften der Organismen. Die Frage, ob die daraus ableitbare strukturelle und funktionelle Vielfalt von mikrobiellen Gemeinschaften ein Kriterium für Bodenqualität sein kann, ist Gegenstand wissenschaftlicher Diskussion. Der Nachweis eines Zusammenhangs von mikrobieller Diversität und wichtigen ökologischen Funktionen des Bodens, die auf mikrobiellen Prozessen basieren, steht noch aus. Das Ziel der vorliegenden Untersuchung war, drei Ansätze zur... |

| Biological soil characteristics such as microbial biomass, community structures, activities, and functions may provide important information on environmental and anthropogenic influences on agricultural soils. Diagnostic tools and detailed statistical approaches need to be developed for a reliable evaluation of these parameters, in order to allow classification and quantification of the magnitude of such effects. The DOK long-term agricultural field experiment was initiated in 1978 in Switzerland for the evaluation of organic and conventional farming practices. It includes three representative Swiss farming systems with biodynamic, bio-organic and conventional fertilization and plant protection schemes along with minerally fertilized and unfertilized... |

| 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... |

| Einleitung • Bodenbürtige Krankheiten verursachen grosse Schäden und sind schwierig zu kontrollieren. • Kompost-Zugabe kann Druck durch bodenbürtige Krankheitserreger reduzieren • ABER: Nicht jeder Komposteinsatz ist erfolgreich. • Möglicher Grund ist die sich während des Kompost-Reifeprozesses laufend ändernde mikrobielle Zusammensetzung. • Es ist weitgehend noch unbekannt, welche mikrobiellen Konsortien wichtig für die suppressive Wirkung von Komposten sind. |

| Preservation or improvement of soil quality and productivity is of major importance for sustainable agriculture. Microorganisms strongly influence these soil characteristics as they are involved in nutrient cycling, transformation processes and soil aggregate formation, as well as in plant pathology or plant growth promotion. A profound understanding of structure, dynamics and functions of soil microbial populations represents one key to the understanding and description of soil quality. Therefore, we analyzed longterm effects of three farmyard manure (FYM)-based farming systems, i.e. bio-dynamic (BIODYN), bio-organic (BIOORG) and conventional (CONFYM), on microbiological soil characteristics and compared them to long-term effects of minerally fertilized... |

| The effectiveness of the bio-fertilizer ‚Effective Microorganisms’ (EM) was investigated in a four years field experiment (2003-2006) at Zürich, Switzerland. The experiment was arranged to separate the effect of the microorganisms in the EM treatments (Bokashi and EMA) from its substrate (sterilized treatments). Crop yields and soil microbiological parameters as soil respiration and microbial biomass were determined. The EM treatments showed no effect on yield and soil microbiology which were caused by the EM microorganisms. Observed effects could be related to the effect of the carrier substrate of the EM preparation. The sampling time showed stronger ef-fects on soil microbial biomass (SIR) and soil respiration compared to the effect of the treatments.... |

| Entomopathogenic fungal isolates identified by morphology as Metarhizium anisopliae may belong to different species when identified by molecular characters. We isolated Metarhizium spp. from an experimental agricultural field under both conventional and organic farming regimes using Tenebrio molitor as bait insect to assess the molecular diversity within the soil. Isolates were analyzed using DNA sequencing and applying SSR markers. Within the former M. anisopliae lineage, we found M. brunneum (86.3%), M. robertsii (11.3%) and M. majus (3.4%) in the soil samples. Several genotypes of each species were identified based on SSR markers. Differences in abundance of the species and their genotypes suggest different adaptations to the soil environment of the... |
