Short summary
This study demonstrates that intensively managed agricultural grasslands can sequester significant amounts of carbon in soils, especially under long-term applications of cattle slurries. There is also evidence that soil carbon sequestration can contribute to offset between 9 % and 25 % of total greenhouse gas emissions associated with the management of permanent grassland. However, to make livestock-based grassland systems more sustainable, further carbon-gain efficiencies are required.
