Rethinking the Use of Waterlogged Wet Arable Land
Many tile drainage systems on arable land are in need of renewal. Cantons and stakeholders will now be given a decision-making tool enabling them to assess such areas in detail and to find sustainable solutions.
Ammonia Emissions from Agriculture in Switzerland for 1990 to 2020
Ammonia emissions from the Swiss farming sector have scarcely declined over the past 20 years. This is because the factors leading to either an increase or decrease in emissions have for the most part cancelled each other out between 2000 and 2020.
Biodiversity in Agriculture: Understanding it Better and Promoting it More Systematically
Agroscope has highlighted for the first time the factors that are key for the targeted, large-scaled promotion of biodiversity in agriculture. Focusing on agriculture as a whole is especially important.
Scoring Points with Plant Protection in Vegetable Crops
Agroscope has developed a scoring system for plant protection in vegetable crops. The system enables the creation of incentives for reducing the use and environmental risks of plant-protection products and promoting preventive and non-chemical measures.
Pollutants in Products Containing Activated Carbon: Improving Detection Methods and Legal Bases
Many consumer goods contain activated carbon, which can be contaminated with pollutants like polycyclic aromatic hydrocarbons (PAHs). Agroscope showed that current analytical methods and legal bases used to address PAH content are incomplete.
Average Grassland Yields in Switzerland Shaped by Summer Drought
Dry summers can see a loss of up to 25% of total Swiss roughage production. This is because grassland yields are strongly correlated with summer drought, as shown by a new analysis conducted by Agroscope and the Swiss Farmers’ Union.
Temporary Carbon Sinks also Benefit the Climate
Storing carbon in the soil in the form of soil organic matter benefits the climate. A new approach allows us to quantify this effect.
More Efficient Nitrogen Use thanks to Site-Specific Fertilisation
A test of five methods using the example of winter-wheat cultivation shows that site-specific nitrogen fertilisation enables more efficient fertilising without adversely affecting yield.
Rising Expenditure for Water Use in Agriculture
The past 30 years have seen a clear trend towards rising water costs. The supply of agricultural land with water from natural sources is thus coming under increasing pressure.
Determining Soil Carbon Storage Potential
Protecting the climate whilst reaping a good harvest is possible if greater amounts of carbon are sequestered in the soil. Agroscope calculated the amount of additional carbon that the soil is capable of storing.
Long-term Monitoring Shows Effective Measures for Reducing Soil Erosion
A long-term field study conducted by Agroscope, the Soil Protection Agency of the Canton of Bern and the University of Bern shows that soil erosion on arable land can be significantly reduced with the right measures – in particular, conservation tillage practices.
Pollinator Flower Strips: Survey Shows Broad Satisfaction in Practice
Farmer acceptance plays a crucial role in establishing optimal flower strips. A survey conducted by Agroscope, FiBL and HAFL shows that pollinator flower strips work in practice, and lead to high satisfaction.
New Plant Protection Product Risk Indicators for Switzerland
Agroscope has developed risk indicators for plant protection products. These indicators highlight risk trends over time for important environmental compartments. Based on sales volumes of active substances, they take account of specific risk reduction measures.
Challenges for Sustainable Soil Management – A Stocktake
The preservation of soil fertility and multiple soil functions faces various challenges both in Switzerland and throughout Europe. A survey carried out in Switzerland among people from practice, government agencies and research highlights problems and possible solutions.
How Much More Water Will Swiss Crops Need in Future?
Model calculations show how climate change will affect the water requirement for different crops grown on the Swiss Central Plateau. This will allow us to proactively plan for crop irrigation and adaptation to the changing climate.
Soil Carbon Sequestration – Offsetting Greenhouse Gases
Together with project partners, Agroscope investigated soil carbon sequestration potentials for 24 European countries. Carbon sequestration could offset 0.1% to 27% of greenhouse-gas emissions from agriculture per annum.

What Quantity of Heavy Metals Ends Up in Agricultural Soils?
Calculations carried out by the Swiss Soil Monitoring Network (NABO) over more than 30 years reveal that fertiliser applications and plant-protection products can lead to excess heavy metals in agricultural soils.
More Cherries and Bigger Apples from Optimal Pollination
Certain crops in Switzerland can benefit from more-species-and-individual-rich wild-bee communities. An Agroscope report shows how this could be achieved.
Risk Maps for Plant-Protection Product Input into Surface Waters
What are the possible routes of entry of plant-protection products into surface waters? Agroscope shows the potential input risks in terms of tile drainage, runoff and agricultural point sources for over 20 000 catchment areas.
More Soil Life in Organic Vegetable Production
Nematodes are important indicators for soil life. An Agroscope study shows that nematode numbers and species diversity are significantly higher in organic vegetable fields than in conventionally farmed fields.
Protecting the Climate with Biochar
An Agroscope study commissioned by the Federal Office for Agriculture shows that the use of biochar clearly has potential, yielding benefits for the climate and ecosystems.
Sustainable Weed Management: Towards New Tools
New tools are being developed to limit the use of herbicides in crops and improve the efficacy of alternative management methods. An update.
Weeds? – Sown Wildflower Strips and Crop-Accompanying Flora Promote Beneficials in Cabbage Production
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.
Losses of plant protection products to water: what is the best risk assessment method?
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.
Managing Conflicting Objectives in Agricultural Production and Water Resource Protection
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.
Quantity and Quality of Semi-Natural Elements within the Swiss Lowland Farmland
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.
Drinking-Water Initiative: Better Water Quality in Switzerland, Higher Environmental Impacts Abroad
In Switzerland, implementing the Drinking-Water Initiative would have positive consequences for the environment, but more food would have to be imported. A life-cycle assessment study by Agroscope analyses the overall impact.
High-Risk Plant Protection Products – Is Effective Crop Protection Possible Without Them?
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 and Hedgerows – Good for Pest Control, Pollination and Yields?
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.
