An estimated half of the carbon fixed by trees is transported belowground, a portion of which
is exuded into the soil where it fuels a complex belowground food web. The biological …

Roots mobilize nutrients via deep soil penetration and rhizosphere processes inducing
weathering of primary minerals. These processes contribute to C transfer to soils and to tree …

Roots are widely acknowledged to be major contributors to ecosystem nutrient cycles.
However, live roots may have very different effects than dead roots, the quality of the soil …

This chapter addresses the role of roots in carbon (C) dynamics by focusing on specific
responses that alter the quantity and quality of belowground organic matter. Roots supply C …

Soil organic carbon (SOC) is primarily formed from plant inputs, but the relative carbon (C)
contributions from living root inputs (ie rhizodeposits) vs litter inputs (ie root+ shoot litter) are …

Forests return large quantities of C to the atmosphere through soil respiration (Rsoil), which
is often conceptually separated into autotrophic C respired by living roots (Rroot) and …

Background The below‐ground component of vegetation accounts for the bulk of plant mass
and vegetation function (eg carbon sequestration) in temperate ecosystems, yet the …

While it is well-known that trees release carbon (C) to soils as root exudates, the factors that
control the magnitude and biogeochemical impacts of this flux are poorly understood.(2) We …

Carbon storage by forests has potential for contributing to 'Kyoto Protocol'greenhouse gas
emission reduction targets, but evidence about C-storage and loss below ground is …

Conserving soil carbon (C) and harnessing the potential for soil C sequestration requires an
improved understanding of the processes through which organic material accumulates in …
