As climate changes, boreal forests to shift north, relinquish more carbon than expected
It's difficult to imagine how a degree or two of warming will affect a location. Will it rain less? What will happen to the area's vegetation? New Berkeley Lab research offers a way to envision a warmer future. It maps how ...
Tillage shows very little impact on carbon sequestration
Reducing or eliminating tillage is one of the farming practices most frequently touted to improve carbon sequestration in soil. A new study by INRA and Arvalis-Institut du Végétal turns this paradigm on its head. This study, ...

Forests lose essential nitrogen in surprising way, find scientists
Even during summer dry spells, some patches of soil in forested watersheds remain waterlogged. Researchers have discovered that these patches act as hot spots of microbial activity that remove nitrogen from ...
