Purchasing decisions have a decisive influence on the demand for organic food. In November 2015, the «Biobarometer Schweiz» study (organic barometer Switzerland) surveyed consumers’ purchasing behaviour, using a standardized questionnaire. The aim of the survey was to investigate the factors determining organic food buying behaviour and to determine which aspects are relevant in consumer communication. The study found that Swiss consumers of organic products are significantly more likely to be female, have a higher level of education and in the majority live in the German-speaking part of Switzerland. Consumers who frequently purchase organic products self-identify as being environmentally-friendly and are conscientious about eating a healthy diet and consuming little meat. In addition to nutritional motives, their purchasing behaviour is primarily influenced by altruistic motives; they also value the organic products’ naturalness and wish to avoid pesticide residues in food. In contrast, within each of the consumer groups, the importance of flavour and aroma for food purchasing decisions increases compared to other motives with decreasing levels of organic consumption. In addition to the sensory aspect of organic food, communication should primarily focus on aspects such as naturalness and environmental compatibility. The Biobarometer Schweiz survey will be repeated at regular intervals in future and will serve to identify changes in consumer trends. © 2017, A M T R A - Association pour la Mise en Valeur des Travaux de la Recherche Agronomique.

The pilot farm Mapraz was set up to give an answer to various questions related to the conversion of farms without livestock to organic farming. After twelve years of evaluation whereof during the last six years two crop rotation systems were compared (one with one year temporarily -TL and one with two years of TL) the result shows that the average wheat yields are 8% lower than the comparability index for wheat or matchable to the organic comparability index for field bean and oat. The contribution margins are between CHF 250.-/ha and CHF 670.-/ha lower than the comparability index in organic agriculture with livestock. The crop rotation system with 2 years of TL presents a better contribution margin (CHF 200.-/ha) and is less labor intensive (-2 hours/ha) than the crop rotation system with 1 year of TL.


This study investigated differences between phenotypes of daughters of artificial insemination (AI)-bulls and daughters of natural service (NS)-bulls, respectively, on organic dairy farms in Switzerland. Organic rules recommend the use of natural mating. Therefore it is of interest whether those two groups of phenotypes show different characteristics on organic farms. Only farms using both AI and NS with sires of the same dairy breed as the inseminated cows were included in the study. First lactations of 594 cows from 29 farms were analysed. Dairy cows descending from NS-bulls showed lower somatic cell scores (SCS), a tendency to shorter calving intervals (CI), and a tendency to lower daily milk yields (DMY) compared to cows descending from AI-bulls. No effects of service method on other analysed health parameters were found. Around 70% of NS-bulls and 26% of AI-bulls had been bred in the same regions as their daughters. 1.8% of AI-bulls and 30.8% of NS-bulls had been bred on an organic farm. One explanation for the effects found in cows descending from NS-bulls might lie in their better adaptation to local conditions. However, effects of the service method and the bull’s environment of origin cannot be distinguished and it cannot be excluded that the chosen NS-bulls incidentally had higher genetic merits for CI and SCS than AI-bulls. © 2016, A M T R A - Association pour la Mise en Valeur des Travaux de la Recherche Agronomique.

The present study examines the efficacy of a homeopathic dry cow prophylaxis in a randomized, placebo controlled case-control field trial. The study was conducted in 24 Brown Swiss farms in the Engadine (Swiss mountain region). The effect of the used homeopathic substances were combined with antibiotics in justified cases. At drying off and in the 3rd and 5th week of lactation the udders were clinically examined and quarter milk samples were taken for bacteriological and cytological analysis. In addition, milk recording data of the first 6 milk testing were included in the evaluations. The used homeopathic prophylaxis at drying off did not show any effect in the incidence of dry cow mastitis and mastitis in the first 120 days of lactation. However, at day 21 post partum significantly fewer animals in the verum group showed a bacteriological finding of a major pathogen, but more animals in this group suffered from a secretion disorder. It has been shown that at the 6th milk test pp significantly more animals of the verum group had a somatic cell count below 100'000 cells/ml than the control group. © 2013 Verlag Hans Huber, Hogrefe AG, Bern.

Swiss agricultural policy is guided by the goal of improving the ecological services provided by farms through direct payments for ecological compensation areas (ECAs), but evaluation programs have shown that financial incentives alone do not guarantee the implementation of ECAs. We investigated, by means of structured interviews with conventional, integrated production, and organic farmers, which role economic, ecological and social motivations play in the decisions by Swiss lowland farmers to implement ECAs. The results show that ECAs are primarily implemented if they are perceived by farmers to be conservation relevant and if they are easily integrated into the farm's workflow. Financial aspects were found to play a more important role than ecological aspects for conventional farmers, while organic and integrated production farmers were found to be more ecologically oriented with organic farmers showing the highest ecological motivation. However, only a weak correlation between motivation and the quantity and quality of ECAs was found. To efficiently increase ECAs, more emphasis should be placed on communicating the benefits of specific measures and on developing instruments that make the farmers' accomplishments apparent and increase their appreciation by farmers and consumers.

In many countries of the northern hemisphere, populations of honey bees and other pollinating insects have been in decline for some years. The causes of this decline have not yet fully been clarified. There are, however, strong indications that intensive agriculture can impact pollinators negatively. Many agricultural activities affect pollinating insects and thus affect the work of beekeepers. Farmers, for their part, depend on the ecosystem service of pollination. Although numerous studies on the health status of honey bees are now available, Switzerland’s beekeepers and farmers have never been asked how they perceive the associated problems and how they view approaches to solving these problems. These issues were explored in a qualitative survey. Results showed that the surveyed farmers generally know little about the problems related to honey bees. Among the beekeepers, perceptions of problems and views concerning solution-oriented approaches are very diverse. Although many beekeepers report negative experiences with agricultural activities, their general attitude towards agriculture is positive. In their view, most problems arise from diseases and parasites of bees, and from the ways that individual beekeepers manage their hives. More care than in the past should be taken to maintain this good relationship between farmers and beekeepers, as the mutual dependence is large. © 2015, AMTRA - Association pour la Mise en Valeur des Travaux de la Recherche Agronomique.

Multi-year studies of the model system ‘cabbage’, the pest ‘cabbage moth’ and the latter’s egg and larval parasitoids (beneficials) demonstrate how pests can be controlled in vegetable production with the help of tailored biodiversity areas. Beneficials were encouraged by means of flower strips on field margins and companion plants within the field. Suitable plants for the flower strips were selected on the basis of the scientific literature and in-house laboratory experiments, and tested in field trials. In laboratory trials, the provision of buckwheat, cornflowers or common vetch extended the lifespan of the cabbage-moth parasitoids by 43% to 85%. Parasitisation of the cabbage-moth larvae increased three- to six-fold over that of the control. In the field trials, flower strips increased the parasitisation of cabbagemoth eggs twofold in one of two years. Used as a companion plant in the cabbage field, cornflowers increased predation on cabbage-moth eggs by 8% to 95% and the parasitism of the larvae by 35% to 68%. The species diversity of broadly effective groups of beneficials (ground beetles, short-winged beetles and spiders) increased by an average of 46% in the flower strips. In one of two years, cabbage heads grown with companion plants were 18% heavier than those grown without cornflowers, and had 41% fewer leaves with feeding damages. © 2016, A M T R A - Association pour la Mise en Valeur des Travaux de la Recherche Agronomique, All rights reserved.
