Nitrate Vulnerable Zone compliance (Scotland): 2008 Action Programme Regulations
What a farm inside one of Scotland's five nitrate vulnerable zones must do under the 2008 Action Programme Regulations, covering the fertiliser and manure plan, storage, nitrogen limits, closed periods, records and the penalties.
If any part of your farm is in a nitrate vulnerable zone (NVZ), you must follow the Action Programme for Nitrate Vulnerable Zones (Scotland) Regulations 2008 (SSI 2008/298). The Regulations apply to the whole farm and the occupier is responsible for making sure they are met. They replaced the earlier 2003 action programme. Scotland has five NVZs: Lower Nithsdale, Lothian and Borders, Strathmore and Fife, Aberdeenshire, Banff, Buchan and Moray (one zone), and Stranraer Lowlands. Check the Scottish Government's NVZ maps to see whether your land is inside one.
The Scottish Government reviewed the Action Programme in 2025. Its response, published on 17 March 2026, says the measures remain appropriate and no changes are planned. The next review is due in 2029.
- Statutory source
- Action Programme for Nitrate Vulnerable Zones (Scotland) Regulations 2008 (SSI 2008/298), as amended
- Enforced by
- The Scottish Ministers, through persons they authorise to enter land, take samples and examine records (regulation 27), in practice the Rural Payments and Inspections Division. SEPA monitors water quality
- Fertiliser and manure management plan
- Prepare it before 1 March each year. It must include a risk assessment map, storage calculation and a nitrogen fertiliser calculation for each crop. You may not apply nitrogen fertiliser to a crop until its calculation is done
- Livestock manure limit
- No more than 170 kg of nitrogen per hectare a year across the whole farm. Grassland farms can apply to the Scottish Ministers for a derogation of up to 250 kg per hectare
- Derogation deadline
- Apply by 30 April of the calendar year the derogation is for. The Scottish Ministers must approve or refuse within 21 days
- Field limit
- No more than 250 kg of nitrogen per hectare of organic manure (other than compost) on any field in a 12-month period, and no more than 500 kg per hectare of compost in a 24-month period, excluding nitrogen deposited by grazing animals
- Storage capacity
- Enough to store slurry from housed pigs for 182 days, housed cattle slurry for 154 days and housed poultry manure for 182 days, plus rainfall and cleaning water. That is about 26, 22 and 26 weeks
- Closed period for chemical fertiliser
- In the Aberdeenshire, Banff, Buchan and Moray zone, 15 September to 20 February on grassland and 1 September to 20 February on other land. In the other zones, 15 September to 15 February on grassland and 1 September to 15 February on other land
- Closed period for high-nitrogen organic manure
- On grassland, 1 September to 31 December on sandy or shallow soil and 15 October to 31 January on other soil. On other land, 1 August to 31 December on sandy or shallow soil and 1 October to 31 January on other soil. Cereals sown by 15 September, and oilseed rape, catch crops or cover crops sown by 30 September, are an exception on the sandy and shallow soil
- Spreading buffers
- No organic manure within 10 metres of surface water or 50 metres of a well or borehole used for a water supply
- Gap between applications
- At least 3 weeks between completed applications of livestock manure to the same area
- Records
- Keep field, crop, fertiliser, livestock and manure records each year and retain them for 3 years from the end of the year they relate to. Derogated farms also keep the plan, fertilisation accounts and soil analysis results
- Penalty for breach of the general duties, record keeping or a notice
- Summary conviction, a fine not exceeding the statutory maximum. On indictment, a fine
- Penalty for obstructing an inspection
- Summary conviction, a fine not exceeding level 3 on the standard scale
What you must do
- Plan before 1 March. Work out each crop's nitrogen need, the manure you produce and your storage capacity. Mark on a map every field, every watercourse, well and borehole, any slope of 12 degrees or more and any field heaps. Use the maximum nitrogen figures in Schedule 3 to the Regulations. The Nmax calculator is no longer available.
- Stay under the nitrogen limits. Keep total nitrogen from livestock manure to 170 kg per hectare across the farm, and within the 250 kg field limit.
- Respect the closed periods. Do not spread outside the permitted dates. Do not apply nitrogen fertiliser to waterlogged, flooded or snow-covered land, or land that has been frozen for 12 hours or more in the last 24, or where nitrogen is likely to reach surface water.
- Have the storage. Keep manure and silage effluent stores free from structural defects and large enough for the periods above. Do not spread slurry with a high-trajectory raised splash plate, except on growing arable crops.
- Keep the records. Keep them for 3 years and let an authorised person enter the land, take samples and examine them.
- Answer a notice. If the Scottish Ministers serve a notice you have at least 28 days to comply and 28 days to appeal to the Scottish Land Court. The appeal suspends the notice until it is decided.
Breaching the NVZ rules is also a cross-compliance breach (SMR 1), so a payment reduction can follow as well as a prosecution.
