Urea represents a common form of organic nitrogen (N)which is added to agricultural soils in large quantities in both cropping (e.g. fertiliser)and livestock (e.g. urine)systems. In addition, there is a small, dynamic ambient pool of urea in soil ass

Amino sugars can be used as indices to evaluate the role of soil microorganisms in active nitrogen (N) cycling in soil. This paper details the assessment of the suitability of gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS)

Although amino sugars represent a major component of soil organic nitrogen (ON), the assimilation of nitrate (NO3 −) and ammonium (NH4 +) into amino sugars (AS) by soil bacteria and fungi represents a neglected aspect of the global N cycle. A deepe
