The degree to which forest ecosystems provide a long-term sink for increasing atmospheric CO(2) depends upon the capacity of trees to increase the availability of growth-limiting resources. It has been widely speculated that trees exposed to CO(2) enrichment may increase the release of root exudates to soil as a mechanism to stimulate microbes to enhance nutrient availability. As a first test to examine how the atmospheric CO(2) and nitrogen availability affect the rates of root exudation, we… CONTINUE READING
