Evidence item

Published literature reports that desert soil CO2 uptake remains undetermined and controversial because evidence is limited to site-scale observations and lacks large-scale experiments, contradicting an unqualified global 1–3 gigaton estimate based only on Mojave soils. DIRECT_TEXT

However, the overall importance of the soil CO2 uptake to Fa is still undetermined. Presently, both the field observations and the laboratory experiments are still limited on site scales. Because of the lack of large-scale experiments, the magnitude of such CO2 uptake is still a matter of controversy.
