N, P & ammonia

These pages tell you a little more about the revised NAP and its key elements. Below are the key changes in terms of N, P and ammonia.

Phosphorous & nitrogen limits

You told us

There are concerns about proposed phosphorus and nitrogen limits, including feasibility, production impacts and lack of clarity.

Our response

A combination of measures to reduce nutrient surplus over time, rather than relying on a single limit. This approach focuses on improving efficiency while allowing flexibility for different farm systems to contribute to overall reductions.


Soil analysis & nutrient planning

You told us

Soil analysis should be mandatory and fertiliser and manure applications should be based on crop need.

Our response

Expanded requirements for soil testing and nutrient management planning, linking fertiliser and manure use more closely to soil need and crop demand.


Air pollution (ammonia) controls

You told us

Nutrient controls should address air pollution as well as water pollution.

Our response

Introduce ammonia mitigation measures including LESSE, urea controls and storage cover requirements, linked to wider air quality policy.


Nutrient efficiency roadmap

You told us

A joined-up, sector-wide roadmap is needed for improving nitrogen and phosphorus efficiency.

Our response

Development of a Nutrient Efficiency Roadmap for NI, co-designed with stakeholders and supported by governance arrangements.


Review phosphorus balance targets for intensive farms

You told us

Proposed phosphorus balance targets, particularly for more intensive farms, should be reviewed to ensure they are sufficient to achieve environmental outcomes.

Our response

Introduction of measures to reduce phosphorus surplus, including a 30% reduction in the national average surplus and requirements for higher stocking farms to reduce P balance through the Nutrient Stewardship Programme or other controls.
