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.

Monitoring systems for indoor housing and home or alpine pastures are gaining in importance owing to their potential for uninterrupted remote monitoring of livestock and for automating administrative tasks. Identitas AG and Agroscope tested the suitability of a sensor ear-tag for cattle for this purpose. The agricultural sector is evolving towards larger farms with bigger…

A quarter fat Appenzeller cheese usually has significantly more holes (‘eyes’) than a full fat Appenzeller. Is this really due to the fat content? Agroscope researchers looked into this issue.

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.

Transport to the slaughterhouse and the time spent in the slaughterhouse are often very stressful for farm animals. A comparative study by the Research Institute of Organic Agriculture FiBL shows that on-farm slaughter can significantly reduce stress for animals.

An ancient fodder crop that had been largely forgotten, sainfoin is experiencing a revival thanks to its ability to reduce ruminant emissions. Agroscope demonstrated a methane- and ammonia-reducing effect for dairy cows fed with fresh sainfoin.

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.

By 2025, the SBB (Swiss Federal Railways) aims to control the vegetation in the track area without herbicides. Agroscope tested the effectiveness of hot-water treatments in a three-year trial and rates this method as a suitable alternative to herbicides.

Agroscope compiles annually updated inventories and projections for Swiss agricultural greenhouse gas emissions. 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.

The dairy sector is urged to reduce negative environmental impacts. But dairy is not only milk: depending on the production system and cow breed, relevant amounts of meat as by-product result. How can emissions thus be allocated to milk and meat?

Pest prevention plays an important role in reducing pesticide use. Nevertheless, the use of such measures is below the social optimum. A generally cautious attitude towards risk and adoption of other risk management measures hinder farmers' prevention efforts.
