Four bar graphs showing photosynthesis and respiration rates in ‘Farthing’ and ‘Keecrisp’ blueberries. P-deficiency reduces photosynthesis in ‘Farthing’ and increases respiration in both varieties.

What happens when blueberries run low on phosphorus?
P-deficiency drives more respiration + exudation, leaving plants with 3–5× less daily C gain. Check out the application note:

Old carbon, new insights: thermal reactivity and bioavailability of saltmarsh soils Abstract. Saltmarshes are globally important coastal wetlands which can help to mitigate the impacts of climate change. They accumulate organic carbon from both modern and aged sources through in-situ...

A fresh perspective on saltmarsh carbon storage linking carbon’s thermal reactivity with its bioavailability. Must read for #CoastalCarbon, #SoilScience & #ClimatePolicy folks bg.copernicus.org/articles/22/... @bluecarbonalex.bsky.social @egu.eu
