Recently, an analysis of more than 100 experiments showed that when carbon dioxide levels increase and plant biomass increases, the amount of carbon that the soil can store will decrease instead.
Terrestrial ecosystems can remove approximately 30% of the carbon dioxide emitted by human activities each year.
One hypothesis is that elevated atmospheric carbon dioxide levels will increase the carbon sequestration capacity of plants and soils, but research by César Terrer and colleagues of Stanford University in the United States shows that this may not be the case.
The researchers analyzed 108 experimental data that increased the carbon dioxide level and found an inverse relationship, that is, when the plant biomass increases with the increase in carbon dioxide level, the carbon storage of the soil will decrease instead.
Experts point out that this mutual growth and decline relationship may be related to the way plants obtain nutrients.
