Goats may be appealing, but very few goat farmers can make money from them. Dairy goats become economically viable only when annual milk production reaches at least 100 tonnes, which equates to around 120 to 180 dairy goats, depending on yield.

Food waste in primary production is rarely recorded – yet this data is key to devising effective reduction strategies throughout the entire value-added chain. This analysis evaluates existing measurement methods with the focus on vegetables. Around 37% of edible food is wasted every year in Switzerland. To address this issue, the Federal Council adopted the…

Designation of regional nature parks in Switzerland significantly boosts the adoption of direct payment schemes aimed at promoting biodiversity conservation (agri-environment schemes, AES), particularly in regions with relatively more intensive farming and low prior uptake of such schemes. Although both regional nature parks and agri-environment schemes (AES) aim to conserve biodiversity, the interaction between these…

Stable yields in plant production are crucial for farm profitability and food security. Model simulations show that the yield stability of many summer crops could decline substantially due to climate change, while winter crops are significantly less affected.

A recent study shows that the risk of exposure during activities involving seeds treated with plant protection products is not always properly understood. Information provided to agricultural professionals should be improved.

Duckweed can efficiently produce protein-rich biomass on nutrient-rich waters, such as wastewater or liquid farmyard manure, while simultaneously binding nitrogen and phosphorus. This presents potential for modern circular economy systems.

Imports from abroad were incorporated into Switzerland’s farm-gate-budget-based agricultural nutrient budget calculation to expand it into a food-system budget. This allows assessment of self-sufficiency, nutrient use and circularity to be assessed in addition to nutrient surpluses.

With the passage of time, crop yield losses can occur on no-till farmland. Researchers from Agroscope and the Universities of Graz and Nevada demonstrated how subsoil compaction can lead to yield losses.

White clover and smooth-stalked meadow grass make a significant contribution to persistence and grazeability in high-yielding fodder-production mixtures. Based on the 2022 to 2024 variety trials, Agroscope can now recommend two new varieties for each of these species.

If we systematically reduce inefficiencies in the food system—such as the heavy use of cropland-based feed, concentrate feed for cattle, and avoidable food waste—we can achieve much higher self-sufficiency while lowering environmental impacts.

The use of vegetable fibre can reduce plant-protection product residues by up to 80% in white musts, with a more limited effect in red musts.. The method can be applied in cellar, as a complement to the responsible use of products in the vineyard.
