Dáil Éireann Debate, Thursday - 8 November 2018
207. Deputy Charlie McConalogue asked the Minister for Agriculture, Food and the Marine the details of data in his Department regarding the reduction in greenhouse gases from reduced low emissions slurry spreading. [46442/18]
View answerUsing trailing shoe, dribble bar or injector systems, termed Low Emission Spreading or LESS technologies contribute to reducing GHG emissions through improvements in nitrogen use efficiency and with a direct impact also on ammonia emission reductions.
The recent Teagasc report ‘An Analysis of Abatement potential of Greenhouse Gas Emissions in Irish Agriculture 2021-2030’ highlighted the potential for greenhouse gas (GHG) abatement to limit the emissions from the agricultural sector over the period 2021 to 2030. One of the measures identified in that document is Low Emission Slurry Spreading, which identified potential mitigation of 0.117 Mt CO2 e/year assuming 50% of slurry applied was by LESS techniques.
Additionally, research1 funded by my Department has shown that on average trailing shoe (Low Emission Slurry Spreading - LESS) equipment reduced ammonia emissions by 36% compared to the use of the splash plate. This is the average reduction across all application timings. Agriculture accounts for 98% of ammonia emissions in Ireland with land spreading of slurry accounting for almost half of this total. Using trailing shoe, dribble bar or injector system to spread slurry is significant in going towards reducing ammonia emissions and complying with our national targets.
Therefore, my Department is supporting a number of measures under the Rural Development Programme in support of low emission slurry spreading (LESS). Under GLAS almost 4,600 farmers are availing of the LESS techniques option, with potential reductions in GHG and Ammonia of the order of 1,420 tonnes of ammonia and 3,260 tonnes of CO2e . While under TAMS there is the option to avail of a 40% grant ( 60% for eligible young farmers) to purchase LESS equipment.
