Climate tipping point of nitrogen fixation

March 8th, 2022

Nature, Other, 08/03/2022
A recent study suggests that the optimal temperature for symbiotic nitrogen fixation rates exceeds the plant’s preferred growth temperature in laboratory conditions. A few degrees of warming could thereby increase or decrease nitrogen fixation rates, depending on the optimal rate among species. […] Previous earth system models found that a substantial amount of additional nitrogen input or new nitrogen was needed to sustain the projected land carbon sink Access options Author information Affiliations CSIRO Oceans and Atmosphere, Aspendale, Victoria, Australia Ying-Ping Wang Department of Ecology and Evolutionary Biology and Department of Global Development, Cornell University, Ithaca, NY, USA Benjamin Z.
