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 inte...
