The changes we reveal in belowground nutrient acquisition may respond to rising atmospheric carbon dioxide, with implications for continued carbon sequestration in mature temperate forests. 5/6

Relative investment into outsourcing nutrient aquisition through root exudation and mycorrhizal production was more choregraphed to seasonal nutrient demands and the lifecycle of the tree, and was enhanced under elevated carbon dixoide. 4/6

Higher atmospheric carbon dioxide increased root branching consistently, showing mature oak trees invest in exploring more of the soil volume in this "do it yourself" strategy. 3/6

At the University of Birmingham Institute of Forest Research (BIFoR) free air carbon enrichment facility in Staffordshire, England, we quantified root exudation and ectomycorrhizal production, alongside root morphology and exudate chemistry across 1 year in a mature oak forest. 2/6

Really pleased to see "The agricultural plastic paradox: Feeding more, harming more?" led by Kai Wang at CAU published. We contextuliase negative tradeoffs of agricultural plastic use with the societial benefits delivered, showing the need for "zero-leakage" rather than "zero-use".
