Nuclear Magnetic Resonance

Advancing Soil Health: Challenges and Opportunities in Integrating Digital Imaging, Spectroscopy, and Machine Learning for Bioindicator Analysis

“…NMR spectroscopy is recognized for its utility in analyzing radiofrequency signals that emanate from atomic nuclei positioned within a magnetic field with particular attention to carbon-13 ( 13 C) or hydrogen ( 1 H) nuclei. 103 According to the review by Audette et al, 104 NMR can be applied to distinguish different hydrocarbon carbon groups in SOM, which is indicated in Figure 8. The review also mentioned that the ratio of alkyl C to O-alkyl C groups is often indicative of the degree of SOM decomposition, as alkyl groups are often more resistant to microbial decomposition while O-alkyl groups are often derived from plant materials and are more labile.…”
