Now we’re looking at how microbial competition for P determines the responses in grasslands to elevated CO2 with @fluxsoilsleaves - focusing on acidic vs calcareous grassland responses to changing atmospheric CO2 @GarethPhoenix @PPS_UoS @BiologyatYork

Your regular reminder that solar farms take up less of the UK than golf courses - even on a pathway to net-zero carbonbrief.org/factcheck-is…

🚨BREAKING🚨 UK emissions in 2023 fell to lowest since 1879, new @CarbonBrief reveals 💷Emissions now 53% below 1990, as GDP up 82% ❤️‍🔥Drop in 2023 largely unrelated to policy ⛰️Coal now lowest since 1730s (!) 🚗Transport is largest sector, then buildings ⚡️Power now likely emits less than farms🐄 1/ carbonbrief.org/analysis-uk-…

Really great day back in Sheffield to give a seminar for @PPS_UoS. Big thanks to @GarethPhoenix for the invite to speak about my favourite subject - swamps!

Therefore, any C allocated below ground by plants simply serves to increase the soil microbial biomass, increasing competition for P between plants and microbes, and reducing acidic grassland plant growth.

These findings may have further global implications, not just for understanding P-limited ecosystem responses to CO2, but also because the contrasting soil chemistries of the two grasslands are representative of ecosystem at contrasting stages of pedogenesis.
