Too little nitrogen may restrain plants' carbon storage capability, U of M paper shows
MINNEAPOLIS / ST. PAUL (10/02/2012) —Plants' ability to absorb increased levels of carbon dioxide in the air may have been overestimated, a new University of Minnesota study shows.
The study, published this week in the journal Nature Climate Change, shows that even though plants absorb large amounts of carbon dioxide and actually can benefit from higher levels of it, they may not get enough of the nutrients they need from typical soils to absorb as much CO2 as scientists had previously estimated. Carbon dioxide absorption is an important factor in mitigating fossil-fuel ...
