| Der oekologische Landbau laesst aufgrund der systemeigenen spezifischen Fruchtfolgen, Duengemassnahmen und Bodenbearbeitung positive Auswirkungen auf die Entwicklung d arbuskulaeren Mykorrhiza und die Kolonisierung der Kulturpflanzen erwarten. Diese positiven Auswirkungen wurden in vergleichenden Untersuchungen ueber die Auswirkungen einzelner Kulturmassnahmen auf die arbuskulaere Mykorrhiza in konventionell und nachhaltig bewirtschafteten Standorten nachgewiesen. Wenn in der Zukunft eine Verringerung des Eintrages an Agrochemikalien in die Kulturlandschaften angestrebt wird, muss der Bedeutung der arbuskulaeren Mykorrhiza eine hoehere Aufmerksamkeit gewidmet werden. Um die positiven Auswirkungen der arbuskulaeren Mykorrhiza in landwirtschaftlichen... |

| Energy crops for biogas production need to be integrated into sustainable and site adapted crop rotation systems, minimising the competition with food production. Luzerne/clover (-grass), sun flower, maize, green-rye + maize and vetch-rye + maize were compared at two sites in Austria with semi-arid (Raasdorf) and humid (Lambach) conditions with and without biogas slurry application. The yield of legumes and fertilised non-legumes at the humid site were 9 % to 56 % higher then at the semi-arid site. The 2-crop system maize following vetch-rye achieved the highest yields at both sites. Slurry from the biogas plant increased the yield only at the humid site. |

| Data on the potential of intercrops to reduce soil nitrate contents, on their N accumulation and biological nitrogen fixation (BNF) are lacking for organic farming in the dry, pannonic region of Eastern Austria. The effect of legumes, non-legumes, and legumes + non-legumes used as intercrops on inorganic soil nitrogen, crop yield and biomass N, and BNF were tested in comparison to bare fallow. Non-legumes and legumes + non-legumes were more efficient than legumes in reducing inorganic soil N contents in autumn and nitrate contents in soil solution from the subsoil in winter. This reduction in inorganic soil N did not last until March of the following year due to an N mineralisation from the mulch. The legume + non-legume mixture contained a larger amount... |

| Das Ziel ist die Erarbeitung von Nutzungsstrategien (Nutzungsform: Schnitt vs. Grünbrache; Artenzusammensetzung: Leguminosenreinbestand vs. Leguminosen-Gras-Gemenge) von Futterleguminosenbeständen während der Umstellungsphase - zur Optimierung der Nutzung des durch Leguminosen gebundenen N durch Folgefrüchte, d.h. - Minimierung des NO3-Auswaschungsrisikos; Verbesserung der Umweltverträglichkeit (Grundwasserschutz); - Optimierung von Ertrag und Qualität der Getreidefolgefrüchte; Weiterentwicklung ökologischer Anbaumethoden darauf hin. Untersuchungsmethodik: - Quantifizierung der N-Mineralisierung von in den Boden eingebrachten Ernte- und Wurzelrückständen von Futterleguminosenbeständen bei unterschiedlichen Nutzungsstrategien, - Quantifizierung der... |

| The demand for high quality organic bread cereals is increasing. In spite of variable grain protein contents, baking quality of organic wheat was found to be acceptable to good. Mycotoxin (DON) contents were generally low on tested grain samples. Choice of the wheat cultivar is the most efficient way to obtain higher grain quality. Fertilization with readily available nitrogen and, to a lower extent, association with legumes and green manuring with mixtures containing fodder legumes can also improve grain quality. Reduced tillage affects soil quality and wheat yield but has little effects on grain quality. |

| The demand for high quality organic bread wheat is increasing. The quality level of organic wheat harvested in EU is mainly dependant on variety, environmental conditions and agronomic practices. In some countries, protein content and composition, influencing technological value, are equivalent to those produced under conventional practices. Beside agronomical techniques, technological processes can help to maintain a good quality. Pre-treatments before milling such as debranning were found to be efficient in reducing DON contamination. The project highlighted the necessity to redefine the methods to assess the quality of organic wheat. |
