The influence of the quantities and ratios dissolved organic carbon (DOC) nitrogen (DN) generated by different chemical quality classes residues on soil microbial processes in decomposition process is not well understood. If DOC-to-DN ratio (hereafter, ratio) substrate close to that C-to-N ratio, then DOC-and-DN stoichiometry balanced, resulting enhanced processing, i.e., use efficiency (CUE). Uncertainty exists about DN CUE, particularly high-quality class (high nitrogen) residue-treated...
Chemical quality of plant residues, which are the source dissolved organic C (DOC), determine molecular structure, notably functional group polysaccharides in DOC, and origins DOC-polysaccharide, transitioned from plant- to microbial-derived as decomposition progressed. The DOC-polysaccharides contribute soil (SOC) stabilization, but what factor associated with residue chemical regulates origin remains unknown. Balanced DOC N (DN) (DOC-and-DN) stoichiometry microbial substrates indicated by...
