Nitrite isotope characteristics and associated soil N transformations.

ABSTRACT: Nitrite (NO₂^-) is a crucial compound in the N soil cycle. As an intermediate of nearly all N transformations, its isotopic signature may provide precious information on the active pathways and processes. NO₂^- analyses have already been applied in ¹⁵N tracing studies, increasing their interpretation perspectives. Natural abundance NO₂^- isotope studies in soils were so far not applied and this study aims at testing if such analyses are useful in tracing the soil N cycle. We conducted laboratory soil incubations with parallel natural abundance and ¹⁵N treatments, accompanied by isotopic analyses of soil N compounds (NO₃^-, NO₂^-, NH₄⁺). The do
