Summary
This review synthesises theoretical and practical aspects of 15N pool dilution techniques for measuring gross nitrogen cycling rates in soil. The authors examine how these isotopic methods can be applied to quantify key nitrogen transformations (mineralisation, nitrification, immobilisation) under varying soil and management conditions, providing guidance for researchers and practitioners seeking to understand soil nitrogen dynamics in agricultural systems.
Regional applicability
The methodological framework presented is internationally applicable and relevant to United Kingdom soil science and agronomy research. The techniques and principles would be directly transferable to UK farming systems and soil monitoring programmes, though specific calibration and environmental conditions would require local adaptation.
Key measures
Gross nitrogen mineralisation, nitrification, immobilisation, and denitrification rates quantified via 15N pool dilution methodology
Outcomes reported
The paper reviews theoretical frameworks and practical methodologies for quantifying gross nitrogen fluxes in soil using 15N isotope pool dilution techniques. It synthesises measurement approaches and their application across different soil and farming contexts.
