Soils possess great potential for sequestering CO2 from the atmosphere in the form of carbon, and thus for mitigating global warming. Agroscope researchers have now shown that in extensive cultivation systems, significantly more carbon enters the soil via plant roots than previously assumed. Based on these findings, the estimated values for the National Greenhouse Gas Inventory were adjusted.

Harnessing the forces of nature and agricultural practice in all its variety - that is diversification. Diversification brings benefits - positive impacts on yields and environmental protection. This is the conclusion of an international study in which Agroscope researchers took part, and which was recently published Advances.

In an in-depth study, Agroscope analysed the possible environmental impacts of implementing the Drinking-Water Initiative. The life-cycle assessment shows that pesticide and nutrient pollution of Swiss water bodies and groundwater could be reduced. In addition, inland biodiversity could be improved slightly. Overall, however, rising food imports would lead to increased environmental pollution.

To control pests without pesticides, genetically modified organisms of the same species could be used. The latter carry a gene that is passed on with above-average frequency via sexual reproduction. This gene possesses traits that directly weaken the pest, or prevent pathogens from being transmitted. But how can the environmental impact of such gene-drive elements be recorded and assessed? Experts from Agroscope have authored a concept study on this topic.

Our soils filter drinking water and produces food. Soils only carry out these services, because they harbour thousands fungal and bacteria species which work together like the wheels in a clock mechanism. These are the conclusions reached by a study published in the renowned by researchers from Agroscope and the University of Zurich. To summarise their findings: the more species-rich the microbial community, the more ecosystem functions remain intact, which in turn has a positive impact on agriculture.

Seed treatments aim to protect germinating crops from diseases. In collaboration with the agricultural cooperative fenaco, Agroscope examined thermal methods using steam and warm water, among others, for the treatment of cereal seed. The results demonstrate the great potential of these methods.

Lutz Merbold will be heading the 'Agroecology and Environment' Strategic Research Division at Agroscope from 1 October 2020. Currently a Research Group Leader at the International Livestock Research Institute (ILRI) in Nairobi, Kenya, he brings his solid knowledge of sustainable agroecosystems to Agroscope. Lutz Merbold takes over from Robert Baur, who has decided to continue his career at Agroscope in the 'Strategy and Corporate Development' Division.

What stresses wild bees? Is it certain plant-protection products, the absence of nutrient-rich foods - or a combination of both factors? Together with research partners throughout Europe, Agroscope is investigating these issues.

The Biosafety Research Group at Agroscope has conducted a review of the literature on genetically modified plants that produce several insect-active Bacillus thuringiensis (Bt) toxins simultaneously. The experts were able to show that the toxins did not pose an increased risk for non-target organisms such as beneficials.

Dr. Joël Bérard will be taking the reins of the 'Animal Production Systems and Animal Health' Strategic Research Division at Agroscope. In this capacity he will become a member of the Executive Board. Currently Head of Research at AgroVet-Strickhof, Bérard will be joining Agroscope on 1 April 2020.
