B52A:
Plant–Soil Interactions Under Global Warming: Learning Mechanisms from Multiyear Field Experiments and Natural Gradients I


Submit an Abstract to this Session


Session ID#: 59850

Session Description:
Ecosystem responses to climate change depend on the feedbacks between plants and soils. Soil resources mediate vegetation growth. In turn, plants control soil properties through the production of organic residues, the supply of photosynthates to the rhizosphere, as well as the association with belowground communities. The interactive effects of these responses have a key influence on soil biogeochemistry and the belowground storage of carbon. In this session we invite contributions from both manipulative field experiments and natural gradient studies that explore the impact of warming on plant-growth dynamics and belowground water, nitrogen, and carbon cycling. Submissions that adopt novel approaches (e.g. molecular, isotopic) or synthesize large-scale outputs focusing on plant-soil feedbacks to warmer temperatures are also highly welcome.
