Agricultural economics 24.11.23

Tarruella M., Huber R., Mack G., El Benni N., Finger R.

Policies for reducing agricultural greenhouse gas emissions are both more effective and more efficient when set at regional rather than individual-farm level. This approach can help us achieve climate targets in a more cost-efficient manner.

Agriculture is aiming to reduce greenhouse gas and ammonia emissions. Agroscope showed that for dairy cattle housing, feed composition plays a role in these emissions as well as wind and temperature.

The root knot nematode (RKN) Meloidogyne incognita causes damage in field and greenhouse crops. Agroscope researchers have developed a new screening test to identify bacteria that antagonise this agricultural pest.

In wheat crops, pesticides can be used more sparingly without sacrificing cost-efficiency. With oilseed rape the situation is more difficult, since the reduced yields are not offset by higher revenues. These are the findings of the analysis of the first two harvest years of the PestiRed project.

Tannin-containing feedstuffs like Acacia mearnsii and sainfoin (Onobrychis viciifolia) have a measurable impact in reducing methane emissions from dairy cows. However, since these feedstuffs in some cases lead to productivity losses, careful consideration must be given to their use.

Soil samples can be measured directly in the field by means of spectroscopy. Agroscope researchers have tested mobile devices and shown how to make the best use of them.

Three widely used and newly revised approaches that optimally complement each other are available to practitioners, trainers and educators. Videos and apps have been designed to facilitate their use.

With CULTAN fertilisation, nitrogen is injected into the soil as an ammonium solution. Multi-year trials conducted by Agroscope show that this method reduces nitrogen leaching by an average 38% without negatively affecting yields.

Agricultural economics 03.10.23

Ritzel C., von Ow A.

Global food availability is expected to remain stable in the medium term. Food security challenges in Switzerland include the decline in agricultural land area per capita, higher incidence of extreme weather events and increased pressure from pests.

Food 28.09.23

Burton-Pimentel K. J., Walther B.

Soya-, cereal-, seed- or nut-based plant drinks are consumed increasingly frequently as milk substitutes. Agroscope researchers have studied the macro- and micronutrients in these drinks and have identified major differences between the plant drinks themselves as well as in comparison with milk.

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.

Nucera E., Huguenin-Elie O., Mayer J., Liebisch F., Spiess E.

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.

Speiser B., Schleiffer M.

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.

El Benni N, Grovermann Ch., Finger R.

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.

Red clover is one of the most important legumes in European forage production. In a multi-year field trial, researchers tested Europe’s largest collection of different red clover accessions at five European locations.

Grapevine nitrogen nutrition is a key parameter for achieving production targets in terms of yield and wine quality. Here we set out the current assessment methods and their interpretation thresholds for sustainable management.

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.

Calanca P., Holzkämper A., Isotta F. A.

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.

Agroscope studied the changes in the agricultural sector over the past twenty years in three Swiss regions and compared them with the visions of three associations: Avenir Suisse, the Schweizer Bauernverband and Landwirtschaft mit Zukunft.

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.
