Article Synopsis
- Denitrification is an essential process in soil nitrogen cycling that primarily occurs in microbial hotspots around particulate organic matter (POM), affecting greenhouse gas emissions like dinitrogen and nitrous oxide.
- To accurately predict these emissions, it's crucial to quantify the distribution of POM, as it influences local oxygen balance and microbial activity in soils.
- Findings indicate that both proximal and distal POM contribute to greenhouse gas emissions, with distal POM significantly driving denitrification rates, particularly in grasslands, highlighting the intricate relationship between soil structure, organic carbon supply, and microbial activity.
On the basis of the principle of reaction continuous-flow quadrupole mass spectrometry, an automated sample preparation unit for inorganic nitrogen (SPIN) species was developed and coupled to a quadrupole Mass Spectrometer (MAS). The SPINMAS technique was designed for an automated, sensitive, and rapid determination of 15N abundance and concentration of a wide variety of N-species involved in nitrogen cycling (e.g.
