Nitrous oxide emissions from permafrost-affected soils

C Voigt, ME Marushchak, BW Abbott, C Biasi… - Nature Reviews Earth & …, 2020 - nature.com
Soils are sources of the potent greenhouse gas nitrous oxide (N2O) globally, but emissions
from permafrost-affected soils have been considered negligible owing to nitrogen (N) …

[HTML][HTML] A review of the importance of mineral nitrogen cycling in the plant-soil-microbe system of permafrost-affected soils—changing the paradigm

E Ramm, C Liu, P Ambus… - Environmental …, 2022 - iopscience.iop.org
