| Zusammenfassung der Studie: Die vorliegende Literaturarbeit ist Bestandteil eines von Coop Schweiz mitfinanzierten Qualitätsprojektes am FiBL und hat zum Ziel, den Stand der vergleichenden Qualitätsforschung anhand von neueren Arbeiten darzustellen, die in zwei kürzlich erschienenen Literaturstudien (Woese et al. 1997, Worthington 1998) noch nicht erfasst sind. Insgesamt wurden 33 Studien ausgewertet. Davon können 19 Arbeiten als Vergleichsuntersuchungen zwischen bio und konventionell im engeren Sinn gewertet werden. Die restlichen Ergebnisse stammen aus Düngungs- und aus Sortenversuchen. 17 Arbeiten sind unseres Erachtens für die Qualitätsforschung von geringer Bedeutung. Neun Studien haben wir als mittel und sechs Arbeiten als wertvoll... |

| Bio allein macht nicht gesünder. Aber Bioprodukte sind ein wichtiger Teil eines nachhaltigen und gesunden Ernährungsstils. Dieses Dossier bringt die Fakten zur Qualität von Bioprodukten und zeigt auf, worin sich Bioprodukte bezüglich Qualität und Sicherheit von nichtbiologischen Produkten unterscheiden. |

| Cocoa is one of the most important export commodities for many developing countries and provides income for millions of smallholders. The expansion of cocoa production has resulted in habitat destruction, biodiversity loss, and soil degradation. The prevalent cocoa production systems worldwide are conventional monoculture full sun systems. Agroforestry systems are argued to be a viable strategy for sustainable cocoa production. However, data-based information on advantages and limitations of different cocoa production systems is limited. Pairwise comparisons on the long-term performance of cocoa monocultures and agroforestry systems under conventional and organic management are inexistent. FiBL is pioneering to fill this knowledge gap with a unique... |

| Die Anbausysteme im modernen Erwerbsobstbau haben sich verändert in den letzten Jahren. Das ist der Hauptgrund für eine komplett überarbeitete Neuausgabe der bisherigen Richtlinien (Heller et al. 1993; Commission romande de fumure, sous-commission arboricole 1993; Ryser et al. 1995). Der Wandel von Sorten, Veredlungsunterlagen, Anbauformen und Pflanzsystemen beeinflusst die Gesamtmenge an Nährstoffen, welche eine moderne Obstanlage braucht, die Aufteilung der Nährstoffe auf die verschiedenen Organe der Pflanze und auch die Nährstoffmenge, welche mit dem Ernteprodukt die Obstanlage verlässt. Damit stellt sich die Frage, wie moderne Anlagen bedarfsgerecht ernährt werden können. Die Anbausysteme sind dynamischer geworden, d.h. sie wandeln sich rascher als... |

| In 1995, an experiment was planted at Wädenswil for comparing organic and integrated apple production. The overall goal of this experiment was to develop a data set which allows for an objective overall comparison of the two production concepts. Horticultural, ecological and economical traits were looked at. In practical terms, the study should particularly clarify how suitable the two systems are for producing marketable fresh fruit under Swiss conditions. The approach of an on-station comparison with a split-plot design with 3 replicate blocks and the factors “production system” (1st factor) and “variety” (2nd factor) was chosen. Ninety-four percent of Swiss apple acreage is managed according to integrated production, and 5% according to organic... |

| With economic indicators from the full cost account and the cash flow statement it is possible to identify the return-risk profile for the organic and the integrated apple production in Switzerland. The full cost account and the cash-flow time line are composed with the managerial-economical software-tool Arbokost. Due to higher (more than 100%) prices in the organic production, growing organic satisfies more return-oriented producers than growing certified integrated. However, the higher return in the organic production is bound to a higher risk. With the certified integrated production (IFP), return and risk are lower. ‘Arbokost’ is an economic farm management software tool for fruit growers. Per orchard it reflects a full cost account, the cash flows... |

| Due to higher prices in the organic compared to the certified integrated apple production, fruit growers are more and more interested in the conversion from integrated to organic production. With the return-risk profile based on Mouron (2001a) it is possible to identify the return and risks with economic indicators from the full cost account and the cash flow statement. Therefore, the return-risk profile serves as a basis for decision- making for producers concerning an evaluation to convert to organic. The return of the organic apple production is about 7% better than the certified integrated production. The risk of the organic production is higher because of the difficulty of braeking the alternanz and loss due to insect pests and diseases. The... |

| Conclusions and further studies The significant reduction of T. pyri and of larvae of predaceous gall midges, the complete loss of mite-diversity and the possible enhancement of P. ulmi and other harmful mites (i.e. C. vitis) are clear disadvantages of lime sulphur. Densities of T. pyri between 0.5 and 1 mite per leaf as mentioned to be necessary for controlling harmful mites (BOURQUIN 1989, FORTMANN 1993, HARZER 1993, KARG 1992, KOHLER ET AL. 1991), were never reached in lime sulphur treatment, while the untreated control always showed densities above this value. On the other hand low densities of predaceous mites are quite normal in intensively sulphur treated, biological orchards and are often replaced by other mite predators, like predatory... |

| Organic viticulture is an important part of the European Union organic farming sector, and, according to the most recent surveys, 1.5% of European Union wine originates from organic farms, with an upward trend. This paper describes an environmental impact of an organic viticulture indicator (EIOVI) that can be reliably used in the management of organic vineyards. The EIOVI can be used as a decision support system for farmers and other property managers by evaluating the potential ecological impact of their choices, thus optimizing management options. The tool allows the simulation of vineyard management based on six agricultural and ecological modules. The EIOVI is a fuzzy expert system that calculates the relationship between the modules on the basis of a... |

| The effects of organic and integrated production systems on the culturable fungal microflora of stored apple fruits from five matched pairs of certified organic and integrated ‘Golden Delicious’ farms were studied at five representative production sites in Switzerland. Isolated fungi were identified morphologically. Colonization frequency (percentage of apples colonized), abundance (colony numbers), and diversity (taxon richness) were assessed for each orchard. The standard quality of the stored fruits was comparable for both organic and integrated apples and complied with national food hygiene standards. Yeasts (six taxa) and the yeast-like fungus Aureobasidium pullulans were the dominant epiphytes, filamentous fungi (21 taxa) the dominant endophytes. The... |

| Einleitung 1997 trat die Blutlaus (Eriosoma /anigerum) in der Schweiz in verschiedenen Bioobstanlagen stark auf. Die Gründe dafür liegen wahrscheinlich in der ungenügenden Parasitisierung der Blutläuse durch die Blutlauszehrwespe. Zwei kalte Winter (1995/96 und 1996/97) aber auch die kühle und nasse Witterung im Mai und Juni 1997 haben die Entwicklung der Zehrwespenpopulationen stark eingeschränkt. Die Schaden waren vielfach enorm und führten nebst Fruchtverschmutzungen zu irreversiblen Trieb- und Knospenschaden, gefolgt von Ernteausfall im Folgejahr, bis zum Absterben ganzer Baume. Die Praktiker begegneten dem Übel mit Mineralölbehandlungen, Entfernung der Kolonien durch Abbürsten bzw. mit einem Hochdruck-Wasserstrahl oder mit viel Geduld für den Aufbau... |
