Now weโ€™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-isโ€ฆ

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.
