| In der Schweiz werden zurzeit rund 600 000 t Trockensubstanz biogene Abfälle recycelt. Längerfristig werden jedoch nur Komposte und Gärgut von einwandfreier Qualität abgesetzt werden können, welche möglichst eine Wertsteigerung der Böden bewirken. Ziel des vorliegenden Projektes ist es, die Qualitätsparameter gezielt in diese Richtung zu erweitern und die Auswirkungen von Kompost- und Gärgutapplikationen auf Pflanzenwachstum und -gesundheit, die Bodenparameter und die Umwelt zu evaluieren. Das vorliegende Projekt ist mit dem Projekt "Organische Schadstoffe in Komposten" der EPFL (Ecole Polytechnique Fédérale de Lausanne) und der Agroscope FAL (Forschungsanstalt für Agrarökologie und Landbau, Zürich Reckenholz) koordiniert. Das Projekt dient gleichzeitig... |

| Evaluating the problem of spotwise appearing cereal growth depressions 23 fields of 10 organic managed farms were investigated. Potential causes were soil nutrients and other chemical and physical soil properties as well as high abundance of the plant parasitic nematodes Heterodera avenae and Pratylenchus-, Tylenchorhynchus and Trichodorus species. In two on-farm field experiments different catch crops and a black fallow treatment caused a decrease of Pratylenchus and Tylenchorhynchus species. However, the yields of the following spring wheat were low, possibly due to H. avenae infestation. Fertilization with compost and potassium had no effect but the H. avenae resistant variety Isotta produced much higher yields. The conclusion drawn was that farmers... |

| Phytophthora disease of strawberry is one of the major problems in strawberry protection. An alternative to chemical treatment needs to be found. Project aims: - Find a sustainable solution to control soilborne diseases by strawberry - Improve the market for quality compost Methodology: - Pot trials to screen the different composts and green manure - Field experiment in an with Phytophthora naturally infested field Results, conclusion, state of the art: Compost and green manure can reduce disease incidence in pot experiments. The evaluation of field experiment has to show, if this reduction is also effective under the conditions of agricultural practise.
