Nitrate regulations in England
Some of the nitrate regulations are aimed at encouraging spreading in the Spring when nitrogen uptake by crops is greater. The current guidance was amended in November 2013:
|Closed periods for spreading organic manures with high available nitrogen, eg pig slurry (but not FYM)||Arable||Grassland|
|Sandy or shallow soils:||1 Aug* – 31 Dec
(*15 Sep where crop sown by this date)
|1 Sept – 31 Dec|
|All other soils:||1 Oct – 31 Jan||15 Oct – 31 Jan|
Organic producers may apply organic manures during closed periods up to 150kg N/ha to certain crops.
From the end of a closed period to the end of February only 30 m3/ha of slurry may be applied at any one time and with at least three weeks between applications.
