Ploughing grass could result in the sequestration of more carbon

Deep ploughing can reduce the amount of carbon released to the atmosphere. \ Carol Dunne
Ploughing grassland has received some bad press lately, due to the release of carbon from the soil. However, new research that Teagasc was involved in examined the effect of deep ploughing grassland on soil carbon sequestration with positive results.
The project examined sites in Ireland, Germany and New Zealand.
Teagasc has stated that ploughing to 40cm (16 inches) results in carbon-rich top soil being deposited to the lower levels of the soil, which protects the carbon stocks.
Dr Dominika Krol, a researcher at Teagasc Johnstown Castle, commented that these carbon stocks are effectively buried to where the soil biology is not as active and so carbon is not released at the soil surface.
