Plant-plant interactions can contribute to yield security and resilience. The significance of these interactions in agriculture is contentious, not least of all because the mechanisms are largely unclear. This study summarises the current state of knowledge.
Incorporating the SOM:clay ratio in the Principles of Agricultural Crop Fertilisation in Switzerland (PRIF) allows us to give more specific agronomic advice at each site based on a broader considera-tion of soil quality.
Genome analysis shows that Japanese beetle populations in Switzerland have different origins. This indicates several entry and dispersal routes – knowledge that can help develop targeted prevention and containment measures.
