Safeguarding the Genetic Diversity of Arvine

A programme has been launched for safeguarding the genetic diversity of Arvine, a grape variety formerly cultivated in Valais. Directed selection would make it possible to exploit this variety's biodiversity and to meet the ecological and economic challenges of the future.

Impoverished Soil Life Reduces Nutrient Efficiency and Increases Environmental Pollution

Nutrient losses in agricultural production are a global problem. A lysimeter test now shows that soil organisms can make a major contribution to increasing nutrient use efficiency in arable farming and reducing nutrient losses.

What Effect Do Tannin-Containing Feeds Have on Methane Emissions from Dairy Cows?

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.

Variability and Clonal Selection of Muscats in the Valais

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.
