英文摘要	Developing an understanding of the transformation kinetics of amino acids in soil is of fundamental importance to probe into the stabilization and decomposition processes central to soil organic matter (SOM) cycling. Considering the transitional function of amino acids in SOM turnover, substrate availability controls the formation and decomposition of soil amino acids critically. However, compared to broad knowledge on free amino acid turnover, how the changing bio-availability of carbon (C) and nitrogen (N) influences the accumulation and turnover of proteinaceous amino acids in soil is not well understood. Therefore, a laboratory experiment was conducted in which soil samples were incubated and supplemented weekly with glucose and N-15-labeled inorganic N as either ammonium (NH4+) or nitrate (NO3-). The concentrations of soil amino acids, differentiated into the newly synthesized (N-15-labeled) and endogenous (unlabeled) portion, were temporally quantified by an isotope-based high-performance liquid chromatography/mass spectrometric technique.
