Novel method to quantify decomposition of rhizodeposits

Rhizodeposition of labile organic carbon is one of the main pathways linking above- and below-ground biota to affect soil carbon cycling. Rhizodeposition is also a strategic physiological process for plants to cope with environmental stress, such as nutrient deficiency and drought, via the interaction with microbes. Nevertheless, separating decomposition of rhizodeposit carbon from root respiration in intact plant-soil systems has not yet been achieved due to methodological limitations, even though rhizosphere respiration has been intensively investigated.
