Als AM (arbuskuläre Mykorrhiza) bezeichnet man eine Symbiose zwischen Bodenpilzen der Ordnung der Glomales und Gefäßpflanzen (Cormobionta). Mehr als 80% aller landwirtschaftlichen Kulturpflanzen bilden eine AM aus. Nur Vertreter der landwirtschaftlich relevanten Pflanzenfamilien der Kreuzblütler (Brassicaceae) und Gänsefußgewächse (Chenopodiaceae) bilden keine AM aus. Der Ökologische Landbau (ÖL) lässt aufgrund der spezifischen Fruchtfolgen, Dünge- und Bodenbearbeitungsmaßnahmen sowie den Verzicht auf chemische Pflanzenschutzmittel ein höheres Besiedelungspotenzial der Böden durch AMP und einen höheren MBG der landwirtschaftlichen Kulturpflanzen erwarten. Während die Förderung des Edaphon im allgemeinen durch Anbaumaßnahmen im ÖL im Vergleich zum... |

A long term field monitoring concerning the development of Organic Farming is performed at the bio-farm “Rutzendorf “ of the BVW GmbH in the Marchfeld region east of Vienna. It is an interdisciplinary project of eleven research institutes, which started in 2003. The aims of the project are: examination of changes concerning soil and plant parameters accompanying the conversion to organic farming; investigation of the effects of different organic fertilisation systems (green manure, communal green forage compost, farmyard manure) on soil properties and on crop performances; analysis of existing biotopes (hedges and field stripes) on the farm, and planning and selective realization of new biotopes with the aim of enhancing the biodiversity of the area,... |

The effect of continuous organic farming (OF) on the arbuscular mycorrhizal fungi (AMF) of winter wheat (Triticum aestivum) was investigated in a greenhouse pot trial. Representative soil samples were taken from 5 farms in the “Weinviertel” region, northeast of Vienna, Austria. On each farm three sites with a different duration of OF were selected for soil sampling; wheat was used as test plant. The mycorrhizal colonization (MC), root length density (RD) and the mycorrhizal colonized root length density (MD) were evaluated for the wheat roots. The majority of the wheat plants indicated an increasing MC and MD with increasing duration of OF. Based on our results we assume that a conversion period from conventional to OF of approximately 15 years is needed... |

The root length density, arbuscular mycorrhizal (AM) colonisation and the total AM root length density of 12 winter wheat cultivars have been studied at seven sites in eastern Austria under organic farming. Root length density did not differ between the cultivars whereas AM colonisation and total AM root density did. Site effects were more pronounced than cultivar effects. All three traits generally were on a higher level in calcaric Phaeozems than in Cambisols. The AM colonisation and total AM root density decreased with increasing plant height and were positively correlated with crop yield. On calcaric Phaeozems, root length density in the subsoil was obviously more important for drought tolerance than AM colonisation in the topsoil. |
