Litter-Carbon Dynamics: The Importance Of Decomposition, Accretion, And Sequestration In Understanding Ecosystem Carbon Cycling, Amy Kochsiek
School of Biological Sciences: Dissertations, Theses, and Student Research
The atmospheric CO2 concentration has been increasing since the industrial revolution. A proposed mitigation strategy is sequestering carbon (C) in terrestrial ecosystems, either in plant biomass or soil organic matter. The litter-C pool is the second largest C pool in agroecosystems post-harvest, and the amount of litter-C loss has been correlated with ecosystem respiration. Yet, the potential importance of the litter pool as one of the major C pools in a system is relatively unknown. We do, however, know that the size of the litter pool can be affected by increases or decreases in both litter-C production and decomposition, …
