Top ten steps to reduce GHGs

TEAGASC has outlined a 10-step programme to help beef farmers reduce their carbon footprint over the coming years as part of agriculture’s contribution to the cutting of Greenhouse Gas (GHG) emissions.

Martina Harrington, Teagasc Beef Specialist, has outlined that 68% of all agricultural GHG emissions in Ireland are methane based while almost all the rest are nitrous oxide – less than 3% are carbon dioxide.

She explained in the latest edition of the Teagasc magazine, Today’s Farm, that methane is a by-product of the digestive system of animals while nitrous oxide (N2O) is a gas caused by the breakdown of nitrogen.

In terms of methane reductions, Martina Harrington, recommends more efficient suckler cows; better daily weight gains from calves; the possible use of feed additives; and an extension of the grazing season to reduce slurry volumes.

As regards nitrous oxide, she recommends a reduction in the amount of synthetic fertiliser to be applied by improving soil fertility, especially in relation to soil pH levels [liming].
