Summary
This paper by Bruce Kimball, a leading researcher in CO₂ enrichment agronomy, reviews and likely meta-analyses experimental data on crop responses to elevated atmospheric CO₂, with particular attention to interactions with temperature, drought, and nitrogen. Published in Agricultural and Forest Meteorology, it is expected to provide quantitative estimates of yield stimulation under elevated CO₂ whilst noting trade-offs including reduced grain protein and mineral concentrations — the so-called 'CO₂ fertilisation' effect and its limitations. The paper likely serves as a synthesis resource for projecting future crop productivity under climate change scenarios.
UK applicability
Whilst the study is global in scope, its findings on CO₂-driven yield stimulation, nutrient dilution, and water-use efficiency are directly relevant to UK arable systems as atmospheric CO₂ continues to rise; UK policymakers and agronomists should consider these interactions when projecting food security and nutritional outcomes under climate change.
Key measures
Crop yield (relative change, %); biomass; water-use efficiency; grain mineral and protein concentration; response ratios across CO₂ treatment levels
Outcomes reported
The study likely synthesises experimental evidence on how elevated CO₂ concentrations affect crop yields, biomass, water-use efficiency, and nutrient composition, and examines interactions with temperature, water availability, and nitrogen supply. It probably draws on FACE (Free-Air CO₂ Enrichment) and other controlled-environment experiments to quantify these responses across crop species.
