The Ulster Farmers Union is reminding farmers of new regulations in Northern Ireland for slurry spreading for the month of February. Under the rule changes, buffer zones have been increased from 10m to 15m away from waterways and from 20m to 30m from lakes. The changes follow a review of the Nitrates Action Programme, which saw the new rules come into effect last October. The amount of slurry that can be spread at any one time has also been reduced to 30m3/ha (2,700 gallons/acre).
