# Nitrates derogation 2026: what changed, who's affected, and what you need to do now

*Published 2026-07-15 by FarmAI Ireland*

Ireland kept the nitrates derogation. The European Commission extended it for three years from 1 January 2026. Qualifying grassland farms can still stock up to 220kg or 250kg of organic nitrogen per hectare, instead of dropping to the standard 170kg. But the conditions got tougher. Grass measuring is now mandatory, training is coming, and the rules tighten again in 2028.

Here's what actually changed, and what it means for your farm.

## What actually happened in December 2025?

For most of last year, nobody could tell you whether the derogation would survive. It was due to expire at the end of 2025. The talk at every mart and discussion group was the same: what happens if it goes?

It didn't go. EU member states approved the Commission's proposal on 9 December 2025, and the formal decision landed just before Christmas. The derogation now runs from 1 January 2026 to the end of 2028.

That makes Ireland the outlier. The Netherlands lost its derogation — its phase-out finished at the end of 2025. Brussels didn't extend ours out of generosity. It extended it because DAFM committed to a long list of conditions, and because the next three years are effectively a trial.

The derogation sits inside Ireland's sixth Nitrates Action Programme (NAP), which also runs 2026 to 2028. Our [nitrates compliance checklist](/read/ai-nitrates-compliance-checklist) describes the fifth programme. The structure is similar, but the numbers below are the current ones.

## Are you a 220 or a 250?

The headline limits didn't change, but where they apply did.

- **250kg organic nitrogen per hectare** — for farms with at least 80% grassland, in catchments where water quality is holding up.
- **220kg per hectare** — applies in areas draining into polluted waters, waters at risk of pollution, or waters showing a worsening trend.
- **170kg per hectare** — the standard limit for everyone without a derogation.

Which side of that line you fall on is not your call. It depends on the water quality data for your local catchment. DAFM has committed to almost 600 detailed sub-catchment assessments over the programme. That means the map of 220kg zones can change as the data comes in.

If your stocking rate sits anywhere near the limits, find out which zone you're in before you plan next year's cow numbers. Your Teagasc advisor can check your townland against the current maps.

## What you have to do to keep it

The derogation is an annual application, not a standing right. Here's what the 2026 terms ask of you:

1. **Apply every year.** Applications go through DAFM's [agfood.ie](https://www.agfood.ie) portal. The 2026 deadline was 15 May 2026 — if you hold a derogation this year, that box is ticked. DAFM announces each year's window on agfood.ie; recent ones have opened early in the year.
2. **Confirm your dairy band.** Dairy farmers confirm their herd's excretion band through ICBF, where the milk data is pre-populated. Miss it, and you're defaulted to the highest band — 106kg of nitrogen per dairy cow — until you sort it. The final deadline for band submissions is 31 December.
3. **Measure your grass.** Derogation farms must record at least 20 grass measurements per grassland parcel per year, each at least five days apart, using DAFM-accepted software. PastureBase Ireland is the obvious free option.
4. **Do the training.** All derogation applicants must complete a new grassland management training programme by the end of 2027.

None of this is optional. The Commission attached these conditions to the extension, and DAFM has to show they're being enforced.

## What tightens in 2028?

The extension is three years, but the third year carries extra weight. From 1 January 2028:

- Derogation farms in areas draining into the **Barrow, Slaney, Nore and Blackwater** rivers and their tributaries face two changes. Chemical fertiliser allowances drop by 5%, and buffer strips along watercourses get wider.
- **Slurry storage requirements for dairy farms tighten.** If your storage is already borderline, 2028 is the year it stops being borderline.

If you farm in the south-east or in Munster's river catchments, that's your two-year warning. Storage is the expensive one. Tanks don't get built in a fortnight, and grant applications add months to the lead time.

## How can AI help you keep up with this?

The honest answer: AI won't measure your grass or build your tank. But the derogation is now a paperwork-and-data game, and that's where it earns its keep.

**Check your own numbers first.** Paste your herd numbers, land area, and dairy band into an AI chatbot and ask it to walk through your organic nitrogen loading per hectare. It's a rough check, not a nutrient management plan — but it tells you in five minutes whether you're near a limit.

**Translate the terms and conditions.** The derogation T&Cs run to dozens of pages. Ask AI to summarise what applies to a farm like yours, then verify the parts that matter against the DAFM documents. Our guide to [reading soil sampling reports with AI](/read/how-to-read-soil-sampling-ai-report) uses the same approach.

**Prepare for the advisor meeting.** A prompt worth stealing:

> "I'm an Irish dairy farmer with a nitrates derogation. Stocked at 235kg organic N/ha, 90% grassland, in a catchment that may be reclassified to 220kg. Give me a list of questions to ask my Teagasc advisor about my options."

The cost of getting this wrong isn't small. Breaching nitrates rules risks cross-compliance penalties that come straight off your [BISS payment](/schemes/biss) — typically 1–5% for a first issue, more for repeats.

## What does it cost?

Applying for the derogation is free. Keeping it is not.

Grass measuring costs time — 20 measurements per parcel adds up, though a plate meter and PastureBase make it routine. The training programme is expected to run through approved providers. And if 2028's storage rules catch you short, you're into real money: slurry storage is a five-figure job on most farms, even with TAMS support.

Against that, losing the derogation costs more. Dropping from 250kg to 170kg means cutting cows or finding land. For a 100-cow dairy farm near the limit, that's not a spreadsheet adjustment — it's a different business.

## Common questions

**Can I still apply for the 2026 derogation?**

No — the 2026 application deadline was 15 May 2026. If you missed it and you're stocked above 170kg organic N/ha, talk to your Teagasc advisor now about managing the rest of the year. Then be ready when DAFM opens the 2027 window.

**Do I need the derogation at all?**

Only if your farm's organic nitrogen loading is above 170kg per hectare per year. Most drystock farms are nowhere near it. It's mainly dairy farms, and beef farms with high stocking rates, that need it.

**Is the derogation safe until 2028?**

The decision runs to the end of 2028, but the 220kg zones can expand if water quality worsens in your catchment. And the next renewal fight starts all over again in 2028 — with water quality data deciding the outcome.

## The bottom line

The derogation survived, but it's on probation. Keep applying annually, measure your grass, confirm your band — and if you're in a south-eastern river catchment, start planning for 2028 now.

Check your zone and your numbers with your Teagasc advisor before you make any stocking decisions.
