Distribution of nitrous oxide emissions from managed organic soils under different land uses estimated by the peat C/N ratio to improve national GHG inventories

Summary

Jeifeld (2018) investigated how peat C/N ratios can be used to predict and distribute nitrous oxide emissions across managed organic soils under various land uses, with the goal of improving national greenhouse gas inventories. The work suggests that C/N ratio is a tractable proxy for estimating N₂O release from these climatically significant soil types. The findings are intended to support more robust reporting of agricultural and land-use GHG impacts in national climate accounting.

UK applicability

Given that the United Kingdom has extensive managed organic soils (particularly in Scotland, East Anglia, and the Somerset Levels) and is required to report detailed GHG inventories under UNFCCC and EU/UK climate frameworks, this C/N-ratio methodology could directly improve the accuracy of organic soil N₂O estimates in UK national inventories and inform peatland management policy.

Key measures

Nitrous oxide emissions; peat carbon-to-nitrogen ratio; land-use category; national GHG inventory estimates

Outcomes reported

The study estimated the distribution of nitrous oxide (N₂O) emissions from managed organic soils across different land-use categories using peat C/N ratios as a predictive tool. The research aimed to improve the accuracy of national greenhouse gas inventories by refining N₂O emission estimates from these high-risk soil types.
