Soil microbial community differences drive variation in Pinus sylvestris physiology, productivity, and responses to elevated CO₂.

ABSTRACT:

Background

Soil microbial communities can affect plant nutrient uptake, productivity, and may even confer resistance to global change. Elevated atmospheric CO₂ is widely expected to stimulate plant productivity; however, this will depend on the availability of growth limiting nutrients such as nitrogen. Soil microbial communities are the main mediators of soil nitrogen cycling and should therefore play a key role in influencing plant responses to elevated CO₂.

Results

To test this, we conducted a controlled, growth chamber experiment with Pinus sylvestris to evaluate how soil microbiome variation influences plant physiology, productivity, and responses to elevated CO₂ (eCO₂; 800 ppm versus 400 ppm in the ambient treatment). Field soils were collected fr
