Abstract
Mid- Infrared Spectroscopy (MIR) is currently being used in soil science to characterize the physical, biological, and chemical properties of SOM by detecting fundamental vibrations of functional groups essential for SOM decomposition and mineralization via microbial functioning. Microbial community composition, size, and activity is influenced by the abundance and composition of SOM, specifically the amount of labile C that is available to microbials. Through MIR spectroscopy, microbial community C use efficiency (CUE) and SOM composition can be analyzed to further characterize the relationships microbial community function and the structural and functional characteristics of labile C in soils to answer the question: Does ratio of labile to stable SOM reflect structural and functional differences between microbial communities at different depths in the soil profile?
