Dear colleagues, We are pleased to invite you to attend and contribute to session H031. 'Measurement and Modeling of Root-Zone Processes Influencing Water, Carbon and Nitrogen Cycles at Various Scales' of the American Geophysical Union (AGU) Fall Meeting 2012 to be held in San Francisco, California, on 3-7 December 2012. This session aims at bringing together scientists from multiple disciplines who use experimental approaches, advance monitoring technologies, and modelling to investigate root-zone processes from rhizosphere to the field scale. The session description is given below. The Submission deadline for abstracts is August 8, 2012.
We are looking forward to meeting you in San Francisco! Best regards, Sarah Garre, Ahmad Moradi, Rebecca Neumann and Gaj Sivandran ===================================== Session Description: Water and nutrient uptake by plants are key processes controlling mass and energy fluxes within the soil-plant-atmosphere continuum. Small-scale hydrological, biological and chemical processes occurring at the root-soil interface around plant roots can have global-scale effects on water, carbon, nitrogen and energy balances. Understanding how various processes interact within the root zone, are affected by root distribution and root behavior, and manifest themselves at the ecosystem scale is critical for predicting impacts of global change and climate variability on carbon, nutrient and hydrologic cycles. The need to incorporate recent experimental and technological advances in experimental techniques that allow for the investigation of root-soil interactions in situ at various scales in numerical models is necessary to unravel the interplay between soil, plant and atmosphere. We solicit experimental and/or numerical investigations focused on plant roots and belowground processes occurring within the rooting zone of diverse ecosystems.
