Rapeseed oil fuel – the crisis-proof home made eco-fuel

End of 2008 the CTI-project �Vegetable Oil Combined Heat and Power Unit� – completed by Agricultural Machinery department of SCA in close cooperation with its governmental funding and private industry partners – could successfully be completed. With the supply of locally produced Renewable Resources Rape Seed Oil and its conversion to power and heat, the…

Effects in winter wheat

The yield of winter wheat grown using three different farming systems (‘organic’, ‘extensive IP’ and ‘intensive IP’) as well as the quality and health of its grains were compared in a long-term trial on Burgrain Farm in Alberswil (Canton of Lucerne, Switzerland). In the organic farming system, the land was ploughed, fertilized with farmyard manure,…

Mesurement of aroma development during the ripening of Golden Delicious apples

In the frame of several research projects in apple breeding and conservation technology at the research station Agroscope Changins-Wädenswil ACW, key factors determining apple quality and the effect of different storage conditions on produce characteristics have been investigated. It is known that, besides classical quality parameters, such as firmness, sugar content and acidity, aroma is…

Crop wild relatives conservation

Crop wild relatives (CWR) are defined as those wild species that are more or less closely related to crops and exchange genes with the latter. Therefore, CWR are an important part of the gene pool of crops. They also have a high potential for crop breeding as well as for their potential use as novel…

The market for meat from the Herens breed in the Valais. Prospects for the organisation of the supply chain

Few market studies have been undertaken of Hérens cattle meat and its development potential. Our paper highlights a situation of high demand and insufficient supply. Nearly half the volume produced is used for home consumption by the farmers, or sold through direct sales, whilst our survey shows that consumer demand and willingness to pay are…

EUROCROP: Research strategy for European arable farming

EUROCROP was a concerted action to develop a research strategy for European arable farming. Research institutes and various stakeholders drew up the main research priorities for individual arable crops and for six transversal elements: “farming systems”, “farm economics”, “outlets and markets”, “quality of agricultural products”, “environmental impacts” and “socio-economic issues”. The social relevance and priority…

Rural innovation networks: from knowledge to development

When do agricultural producers invest in new harvesting technology, change the rotation of crop and fertilisation, reorient their production or use new marketing channels? Over the last years the use of advanced knowledge and technology in agriculture has become more and more important. Farmers, as well as agro-industry companies that provide agricultural input or buy,…

Phenological annual review for 2008

Although the year 2008 in Switzerland belongs to the 10th to 12th warmest years since the beginning of measurements, the effects on the development of the vegetation were not very striking. An extreme excess of heat was never registered except of the winter months and May. The mild winter simply had an effect on the…

Land tranfers and development of farm structures until 2007

Economies of scale can significantly improve the competitiveness of the Swiss agricultural sector. In order to understand the development behind the farm size structure, the underlying sub-processes of land transfers are examined in-depth. Each year, between 4 % and 5 % of the total utilised agricultural area are transferred due to the closing down or…

Indicators for ecological quality in alpine pastures

Vascular plants are helpful indicators for the ecological quality. In the context of the Ecological Quality Ordinance they are already used in the utilized agricultural area. Recently, criteria to assess the ecological quality of summer pastures have been discussed. ART has identified the vascular plant taxa, which best represent species richness, the occurrence of Red…

Increasing phasing out of organic agriculture – with an upward trend

Since 2004, the number of organic farms has been declining steadily contrary to the positive trend in demand. Between 2005 and 2007, 263 or 4.1 percent of organic farms were lost. An analysis of data from the Federal Office for Agriculture’s Agricultural Policy Information System (AGIS) shows that 2.0 percent of the farms converted from…

Acceptability of new pratices by cattle breeders: advantages of a sociological approach

In the PASTO project, experimental agricultural practices with the Herens breed of cattle have been tested. We assessed their acceptability by the cattle breeders to check their chances of being implemented and in what conditions. To do this, we analysed different existing practices in the central Valais, as well as the value system and their…

The PASTO project: an innovative agricultural system of pratices for mountain regions

Mountain agriculture faces numerous challenges: diminishing number of farms and of animals, advancing of the forest, search for viable economic alternatives and multiple social demands concerning the maintenance of landscapes, of biodiversity and the offer of local quality products. Within this context, the PASTO project is testing and developing extensive production methods for meat of…

Willingness to grow genetically modified plants in Switzerland

Interviews were conducted with farmers in the canton of Zurich as part of a project by the national Research Programme on Genetic Engineering (NFP 59). The object was to assess their willingness to use genetically modified crops. 31 % of those surveyed would consider using the technology, while 62 % were against. These differing attitudes are reflected…

Floristic evolution of nutrient-poor grasslands in the Alps

The nutrient-poor, semi-natural grasslands of the Swiss Alps are amongst the most species-rich habitats in Europe. To investigate changes over 25 years in the diversity and floristic composition of these plant communities, we repeated a total of 151 phytosociological relevés, originally recorded between 1975 and 1985 in Château-d’Oex, Grindelwald, Tujetsch und Sent. In this second…

Soil damage by tractor pulling

Between 2002 and 2006, tractor pulling events were carried out once a year on a deep luvisol on arable farm land in Niederbipp (BE). Since severe mechanical stress was anticipated particularly within the track area, the authorization of the event was subject to conditions stipulated by the cantonal soil protection service with the aim of…

Comparison of wood-fired heating systems

The use of wood fuel for heat generation has been increasing steadily in recent years. Wood-fired heating systems do not only make economic sense for woodland owners; more and more often non-woodland owners are having their heat supplied by wood-fired power stations. Three output categories of wood-fired system were compared: 20, 60 and 100 kilowatt…

Economically sustainable apple farming

Which factors and strategies are effective for economically sustainable apple farming? On this research question the Agroscope Changins-Wädenswil Research Station (ACW) has conducted a representative survey in co-operation with the Fruit Union Swiss (SOV). This article summarizes the results about the IP producers. Data analysis shows that commercialisation, production costs and apple orchard size are…
