Abiotic hydroxylamine nitrification involving manganese- and iron-bearing minerals.

Hydroxylamine (NHOH) undergoes biotic and abiotic transformation processes in soil, producing nitrous oxide gas (NO(g)). Little is known about the magnitude of the abiotic chemical processes in the global N cycle, and the role of abiotic nitrification is still neglected in most current nitrogen trace gas studies. The abiotic fate of NHOH in soil systems is often focused on transition metals including manganese (Mn) and iron (Fe), and empirical correlations of nitrogen residual species including nitrite (NO), nitrate (NO), and NO(g).
