Understanding the critical links between soil carbon and nitrogen cycling processes in forest ecosystems is necessary for developing effective site management to enhance forest productivity and environmental benefits. In the first application of 14N-nuclear magnetic resonance (NMR) to soil humic acid (HA), we have discovered that surprisingly nitrate-N is present in soil HAs, with the HA-nitrate N extremely sensitive to forest management practices. This project represents the first attempt to integrate the use of advanced NMR and stable isotope techniques to examine both chemical and biological linkages between carbon and nitrogen cycling processes in Australian and US forest ecosystems.Read moreRead less
