Demand, supply and value of insect pollination for the swiss agricultural production

For some field crops, and especially fruits and berries, harvested yield quantity and quality are dependent on pollination by insects. According to global estimates, honeybees and wild bees contribute equally to this ecosystem service, although there are no systematic studies for Switzerland. Now, for the first time, and with the help of data on the…

Increased SOM stocks in a seven-year-old agroforestry system in central Switzerland

Modern agroforestry systems have the potential to combine productive agriculture with increased environmental benefits. Because these systems have only recently been tested by a few farmers in Switzerland, there is hardly any data available on the environmental impacts of modern agroforestry systems. In this study, we examined the changes in soil organic matter (SOM) stocks…

Agricultural extension gives rise to greater proportions of biodiversity priority areas of higher quality

The shortage of high-quality Biodiversity Priority Areas (BPAs) is one reason for the ongoing decline in biodiversity in the cultural landscape. Many farm holdings have the potential to increase the quality of their BPAs. One approach to leveraging this potential is whole-farm extension, which takes into account both the ecological and economic parameters of the…

Reduced tillage in organic farming – climate aspects

The conversion from ploughing to reduced tillage is discussed in the context of increased humus accumulation as an opportunity to mitigate climate change. To date, little attention has been paid to the question whether reduced tillage systems in organic farming result in increased nitrous oxide (N2O) emissions. Thus, as part of FiBL’s long-term tillage trial…

GM potato plants are resistant to late blight

Late blight of potato, caused by the pathogen Phytophthora infestans, is the most significant disease in potato cultivation. Large quantities of fungicides are used to control this disease. New, resistant varieties of potato have heretofore not caught on, owing to deficiencies in agronomic traits or tuber characteristics compared to the established breeds. Agroscope studied genetically…

Nitrogen fertilisation of linseed influences seed yield and oil quality

Despite the oilseed production payment, linseed has remained a relatively unimportant oil plant in Switzerland. Nitrogen (N) fertilisation is a core component of linseed cultivation, since linseed is considered to be a fairly undemanding crop, yet one that is susceptible to lodging when over-fertilised with N. With the aim of studying the reaction of recently…
