How do fine root traits of fast-growing trees promote soil organic carbon stabilization?

ABSTRACT:

Background and aims

Soil represents a larger reservoir of soil organic carbon (SOC) than terrestrial vegetation, offering a great potential for reducing the widespread adverse consequences of climate change. In forests and tree plantations, fine roots significantly impact SOC stabilization through their functional traits. However, it is not obvious which fine root traits between those related to chemistry (easily decomposable or recalcitrant), architecture or morphology are the most conducive to SOC stabilization in phylogenetically related fast-growing trees. We assessed the effects of root functional traits on SOC storage and stabilization.

Methods

We studied five hybrid poplar clones with different root traits located in New Liskeard, ON, Canada. We collected soil cores a
