The proposed research program will employ an array of novel molecular tools that provide detailed information about soil organic matter (SOM) composition, biogeochemistry and ecosystem function. These tools, which have been pioneered by my research group, involve both targeted and non-targeted approaches using using mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy; arguably two of the most advanced structural techniques available in modern science. These techniques will be used to study the SOM in soil samples collected from several long-term field experiments in collaboration with University researchers in the United States. This program will also examine SOM mechanisms using innovative lab-based experiments.

拟议的研究计划将采用一系列新的分子工具，提供有关土壤有机质（SOM）组成，土壤地球化学和生态系统功能的详细信息。这些工具由我的研究小组开创，涉及使用质谱（MS）和核磁共振（NMR）光谱的靶向和非靶向方法;可以说是现代科学中最先进的两种结构技术。这些技术将用于研究与美国大学研究人员合作的几个长期田间实验中收集的土壤样品中的SOM。该计划还将使用创新的实验室实验来研究SOM机制。
