The Irish Grain Growers Group (IGGG) has said it will have to consider its position on supporting the retention of the nitrates derogation going forward if the proposals from the Nitrates Expert Group are carried.

The group said that the tillage recommendations for the NAP are based on modeling “with little or no scientific evidence, especially on [the] post-harvest cultivation element”.

The IGGG said the proposals will add cost, workload and mental stress to tillage farmers in a busy time.

Commenting on the banning of spreading high nitrogen organic manures on tillage land in the autumn, the group said there is “a deep lack of concern and understanding for tillage farmers from people advising policy”.

IFA grain committee chair Kieran McEvoy has said a blanket ban on spreading high nitrogen organic manures ahead of autumn crops would have unintended consequences and that the focus on spring application would have huge logistical issues, not least getting 20t spreaders onto tillage land after a wet winter.

He noted that stubble cultivation rules caused widespread confusion when introduced and new rules will add to this. He welcomed the cut off date for cultivations being moved to 31 August, but noted 15 August would be a more realistic date.

The IFA said it is continuing to engage with Department of Agriculture officials on the proposals.
