An expert working group led by the former president of the Ulster Farmers’ Union, Dr John Gilliland, has presented a report to DAERA which outlines various measures aimed at tackling the problem of ammonia emissions within NI agriculture.The report, under the heading of Making Ammonia Visible, is from the same expert group that produced a sustainable agricultural land management strategy in October 2016. That work mainly focused on improving water quality in NI, principally by reducing and making better use of phosphorus within agriculture.
