Summary

This 2017 field study used 15N labelling to examine nitrogen fate in irrigated maize under two treatments: conventional ammonium nitrate fertiliser and the same fertiliser amended with DMPSA, a nitrification inhibitor. The work contributes to understanding how nitrification inhibitors influence nitrogen cycling pathways and plant-available N in irrigated cereal systems, as suggested by the isotope tracer approach and focus on DMPSA efficacy.

UK applicability

The findings may have limited direct applicability to UK maize production, as irrigation is less common in the United Kingdom and soil/climate conditions differ substantially from Spain. However, insights into nitrification inhibitor performance could inform N management strategies for UK arable systems under future climate or intensification scenarios.

Key measures

15N isotope tracing; nitrogen recovery in plant biomass; soil mineral nitrogen; nitrification rates; potentially nitrous oxide emissions or nitrate leaching

Outcomes reported

The study tracked the fate of 15N-labelled ammonium nitrate in irrigated maize crops, comparing nitrogen recovery and loss pathways with and without the nitrification inhibitor DMPSA. Measurements likely included plant N uptake, soil N transformations, and gaseous N losses.
