Soil Moisture Sensitivity Of Microbial Processing Of Soil Organic Carbon, Shikha Singh
Soil Moisture Sensitivity Of Microbial Processing Of Soil Organic Carbon, Shikha Singh
Doctoral Dissertations
Soil organic carbon (SOC) is the largest terrestrial C pool and understanding SOC decomposition in response to environmental factors is critical for accurate predictions of climatic change. Soil moisture is one of the most important, yet less explored, environmental factors controlling soil microbial respiration. The relationship between soil moisture and respiration also varies with soil texture. Currently, it is difficult to predict feedbacks to climatic changes from changes in soil moisture, as most earth system models lack site-specific, experimentally-derived parameters to represent soil moisture-texture-respiration relationships. The overarching goals of this dissertation are to gain a fundamental understanding of the interactive …
