Different cultural backgrounds lead to different uptake of biodiversity agri-environmental schemes at the inner-Swiss French-German language border. Economic policy incentives could mitigate culture-driven behavioral differences.

Cheese varieties from Switzerland are characterised according to various criteria. Agroscope analysed the free volatile carboxylic acids in ten cheese varieties and demonstrated that the latter are suitable for characterisation and differentiation.

Symbiotic nitrogen fixation by bacteria in the soil coexisting with legumes leads to reduced fertiliser requirement. It is not easy to measure this variable on farms, however. Now researchers from Agroscope have developed a method for estimating nitrogen input via symbiotic fixation at farm level.

The agricultural sector as an aggregate proved resilient to the COVID-19 shock. But how did it impact agribusiness firms within the sector? Using the Swiss case, we provide the first set of evidence on how agri-food importing firms survived the pandemic economically.

Safeguarding the clonal diversity of Muscats in the Valais has enabled the characterisation of 42 Muscat à petits grains and 36 Moscato Giallo clones. The characteristics of the two are quite distinct, particularly their aromatic potential. The best clones will be included in the Swiss certification scheme.

Tuta absoluta is one of the most destructive pests of solanaceous crops. Agroscope has developed a statistical model to study the population dynamics of the pest and its parasitoids and allows interventions to be optimally planned.

Swiss vineyards are often small and arranged in a mosaic of separate plots and management practices. Therefore, it can be assumed that spray drift from conventional to organic vineyards occurs regularly. Nevertheless, no pesticide residues are detected in most organic wines.

Agricultural economics research uses a multitude of methods and approaches to assess existing and new policy measures. This is the basis for agricultural policy that demonstrably makes a difference, i.e. is evidence-based.

Bread, sauerkraut, cheese, wine, beer, yoghurt, chocolate, coffee, kimchi, tempeh, soy sauce, miso, etc. – all these are fermented foods and are part of our daily diet. What exactly are fermented foods and what role do they play in a healthy and sustainable diet?

Pre-flowering leaf removal is a recent practice in viticulture. As well as reducing fungal disease pressure, it limits yield and improves grape composition. An Agroscope study shows that mechanising pre-flowering leaf removal saves effort but also involves risks.

With increasing global and regional temperatures, even in Switzerland the growing season has lengthened considerably. Using data from the Federal Office of Meteorology and Climatology, Agroscope has traced the development of the growing season since the start of the previous century.

Tomato is a special case among vegetables, as its seeds can only be extracted from the pulp after a fermentation step. In order to optimise this working process, various harvesting frequencies and extraction timepoints were tested at the Research Institute of Organic Agriculture FiBL.

Even in temperate climate zones, an increase in the ambient temperature and solar radiation can cause heat stress in grazing dairy cows. Agroscope studied the physiological changes in cows caused by increasing heat load.

Perennial ryegrass is one of the most important forage grasses in Swiss agriculture. Agroscope can now recommend three new cultivars based on the results of variety tests conducted from 2020 to 2022. Three further varieties also showed promise but are yet to be approved.

To calculate erosion risk in Swiss field crops, the effect of different arable crops on the risk of erosion was determined. Calculations for the whole of Switzerland show that although erosion risk is on average low, it is not negligible everywhere.

In dairy cows, herbage-based diets often lead to increased nitrogen excretion. Tanniferous sainfoin and extract of acacia can reduce nitrogen excretion from urine and thus ammonia volatilization from slurry.

Excessive nitrogen inputs from the air lead to over-fertilisation of sensitive ecosystems. Continuous feeding optimisation can make an important contribution to reducing ammonia losses and thus nitrogen inputs.

Agroscope researchers calculated the nitrogen and phosphorus inputs into Swiss water bodies for the year 2020. Although these inputs decreased in comparison to 2010, the 'agriculture' environmental target for nitrogen inputs was missed by a significant margin.

The consumption of raw-milk products is considered to be healthy, but is not entirely risk-free due to the possible presence of pathogenic bacteria. Agroscope and BFH-HAFL investigated the microbiological safety of raw-milk yoghurt and showed that this is protected in several respects by fermentation.

With the change to reporting under the Paris Agreement, new bases for calculation must be taken into account. Despite this, the overall picture for agriculture remains largely unchanged.
