Important aspects of plant-soil interactions are mediated by rhizosphere processes: Plant nutrient acquisition Root colonization by rhizosphere microorganisms Soil organic matter decomposition Increasing CO 2 concentration primarily affects processes at the leaf or canopy level Increase in plant primary production, Decrease in water-use Altered carbon allocation These changes at the vegetational level modify processes in the rhizosphere including Root growth Root turnover Rhizodeposition Nutrient and water uptake Microbial activities and associations Altered rhizosphere processes lead directly to changes in soil nutrient availability and organic matter decomposition, which affect overall tree growth and soil carbon storage (or loss to atmosphere).
