One of Earth’s giant carbon sinks may have been overestimated - study

In a nutshell, this meta research paper finds that significant increases in atmospheric CO2 will increase forest and grasses growth rates, but not necessarily the amount of carbon in the soil. Forest soil carbon actually declines after a certain amount of increase in atmospheric carbon. The article has a link to the paper’s abstract.
Does this strengthen the argument for making biochar vs planting trees?
