Root traits and soil micro-organisms as drivers of plant-soil feedbacks within the sub-arctic tundra meadow
Plant-soil feedback (PSF) results from the influence of plants on the composition and abundance of various taxa and functional groups of soil micro-organisms, and their reciprocal effects on the plants. However, little is understood about the importance of fine root traits and root economic strategi...
