Download Review of FACE (Free Air Carbon Dioxide Enrichment) results in relation to impacts of elevated carbon dioxide on future farm practices

Researchers took data from a long-term experiment on elevated atmospheric carbon dioxide (CO2) impacts on grassland and applied them to a real farm. They used an ecosystem model and a farm system optimisation model to compare the current farm with the farm in the future under elevated CO2. The future farm made more profit but required more P fertiliser, greater management input and had higher farm total greenhouse gas emissions. The next stage should be to run the farm with climate as well as CO2 changes.
