Above-ground and below-ground plant responses to fertilization in two subarctic ecosystems
Soil nutrient supply is likely to change in the Arctic due to altered process rates associated with climate change. Here, we compare the responses of herbaceous tundra and birch forest understory to fertilization, considering both above- and below-ground responses. We added nitrogen and phosphorus t...

Soil nutrient supply is likely to change in the Arctic due to altered process rates associated with climate change.
