Summary

This 2021 study examined carbon dynamics in drained agricultural peatland after coverage with mineral soil, a widespread practice intended to improve agricultural productivity. Using radiocarbon dating, the authors quantified soil carbon loss rates and assessed whether mineral soil coverage mitigates ongoing carbon losses from the degrading peat substrate. The findings contribute to understanding greenhouse gas emissions and carbon balance in converted peatland systems.

UK applicability

The United Kingdom has substantial lowland peat soils, particularly in East Anglia, parts of Scotland, and the Somerset Levels, many of which are under agricultural drainage. This research's findings on carbon loss mechanisms from drained peatland are directly relevant to UK policy on peatland restoration and agricultural emissions accounting.

Key measures

Soil carbon stocks, radiocarbon-derived carbon loss rates, soil respiration or CO₂ flux measurements from peatland under mineral soil coverage

Outcomes reported

The study measured soil carbon loss rates from drained agricultural peatland that had been covered with mineral soil, using radiocarbon dating and carbon flux measurements. The research quantified the magnitude and timing of carbon loss under this common land management practice.
