FiBL field trials demonstrate that sown wildflowers together with the spontaneous arable weed flora in cabbage fields can promote predatory beneficial insects and pollinators. This makes it possible to enhance the ecological value of production areas.

Run-off and erosion contribute to the pollution of water by plant protection products. Targeted measures to reduce this pollution require detailed field analysis. Existing methods have now been compared for the first time in order to assess their suitability.

In Swiss agriculture, conflicts arise between production and the protection of water resources. These were studied by means of multi-criteria decision analysis (MCDA): objectives are defined, evaluation functions proposed and measures analysed.

In the Swiss lowland, the quantity of biodiversity promoting areas (BPA, i.e. options of the Swiss agri-environment scheme) clearly exeeds the stipulated 7%.The quality of the BPA has been improved as well. However, three forth of the BPA are still barely recognizable as semi-natural areas in the field.

Agroscope examined whether it is possible to forgo the use of PPPs with a high risk potential for the environment. The results show that this would make effective crop protection more difficult, especially for field and vegetable crops, but also in organic farming.

Sown wildflower strips improve pest control, and diverse, perennial strips also improve pollination services. Hedgerows in Switzerland yielded good results, while internationally effects were inconsistent. The effects on yield were variable.

Ever decreasing amounts of plant-protection products are being used in field crops; however, the quantity alone does not determine the risk for the environment, as discussed in a new Agroscope study on the use and risk of plant-protection products in Swiss field crops.

In order to understand the diversity of insects colonizing oilseed rape, a survey focusing on beetles was conducted in a plot of winter rape in Agroscope Changins (Prangins VD). Beetles were captured with yellow water bowls over the whole cultivation period from August 2017 to June 2018. In total, 11,856 individuals were caught from exactly…

Recent studies show a decline in the abundance and diversity of wild pollinators, as well as an increase in honeybee mortality. These pollinators are an integral part of biodiversity and play an essential role in the growing of certain crops and in wild plant reproduction. In the Swiss cantons of Vaud and Jura, and in…

Plastic products are omnipresent in our everyday lives and are so versatile and efficient that it is difficult to imagine modern agriculture without them. However, in combination with littering and as foreign materials in digestate and compost fertilisers, they are also the main source of plastic inputs on agricultural land. Using material flow analysis, this…

Nowadays, the term «sustainability» is ubiquitous – in politics, in science, and in everyday speech. What it means, however, and what ideas are associated with it, varies significantly. Thus, for example, the social dimension is largely neglected in the discourse on sustainability. Perception of sustainability is influenced inter alia by the media, political programmes or…

The intensification of agricultural practices has led to an alarming decline in farmland biodiversity. With the aim of stopping and even reversing this trend, biodiversity promotion areas (BPA – formerly named «ecological compensation areas») were introduced in the 1990s. In this study, the influence of BPA on the biodiversity of butterflies and breeding birds was…

Phosphorus is an essential nutrient for plant growth. Switzerland is reliant upon the import of phosphorus fertilisers, which come from deposit reserves and are increasingly burdened with pollutants. On the other hand, there are hitherto unused phosphorus stocks in sewage sludge and slaughterhouse waste that could completely replace fertiliser imports. Therefore, Switzerland has introduced the…

The Swiss agricultural and climate policy- making sector has set itself the target of reducing agricultural greenhouse gas emissions by at least one-third by 2050 compared to 1990’s figures. This target can be achieved via technical measures on the production side and/or by reorganising agricultural structures (area percentages, animal populations). Animal husbandry is responsible for…
