Irish dairy and livestock farmers continue to face increasing pressure under the Nitrates Derogation. Rising land lease costs, tighter nutrient management requirements, and uncertainty around future regulations have left many farms looking for practical ways to maintain productivity while remaining compliant.
Although Ireland has yet to implement the new EU RENURE framework fully, the legislation presents an interesting opportunity. In theory, qualifying RENURE fertilisers could allow farmers to recover surplus nitrogen from livestock manure, reducing pressure on their organic nitrogen allowance and making greater use of the additional mineral nitrogen allowance available under the new rules.
The Challenge of Nitrates Derogation
Many intensive dairy farms produce more organic nitrogen than they can utilise within the standard limits of the Nitrates Directive. Traditionally, farmers have relied on several options to remain compliant:
- Leasing additional land.
- Exporting slurry to neighbouring farms.
- Reducing livestock numbers.
- Purchasing additional fertiliser to balance nutrient requirements.
Each option carries financial or operational costs that can affect long-term farm profitability.
Table 1: Traditional Options for Managing Organic Nitrogen
| Option | Potential Challenge |
|---|---|
| Lease additional land | Rising rental costs |
| Export slurry | Transport and handling costs |
| Reduce livestock | Lower production potential |
| Continue current practice | Increased compliance pressure |
Where Could RENURE Make a Difference?
RENURE introduces a different way of thinking about nutrient management.
Instead of viewing livestock manure solely as an organic fertiliser, nutrient recovery technologies process manure or digestate into products with a higher proportion of readily available nitrogen. Under the new EU framework, qualifying RENURE products can be treated differently from untreated organic manure, subject to national implementation and regulatory requirements.
In theory, this creates an opportunity to recover surplus nutrients already available on the farm rather than relying entirely on imported mineral fertilisers.
Rather than increasing the amount of nitrogen applied, the focus shifts to improving the management and utilisation of existing nutrients.
A Different Approach to Nutrient Planning
If implemented in Ireland, RENURE could provide farmers with greater flexibility when planning nutrient applications.
Potential advantages may include:
- Recovering nitrogen from existing manure resources.
- Reducing dependence on purchased fertilisers.
- Improving nutrient efficiency across the farm.
- Supporting more accurate nutrient management plans.
- Reducing pressure to secure additional leased land in some farming systems.
Every farm is different, and the benefits will depend on factors such as stocking rate, land availability, crop requirements, and national regulations.
Table 2: Traditional Nutrient Management vs a RENURE-Based Approach
| Traditional Approach | Potential RENURE Approach |
|---|---|
| Organic manure counted within the organic nitrogen limit | Part of the recovered nitrogen may qualify under the RENURE framework* |
| Greater reliance on purchased fertiliser | Greater use of recovered farm nutrients |
| Additional land often required. | Improved nutrient efficiency may reduce pressure on land requirements. |
| Slurry viewed as a waste management issue | Slurry viewed as a nutrient resource |
Could Farmers Reduce Their Costs?
One of the most attractive aspects of RENURE is the opportunity to improve farm efficiency rather than reduce costs.
Research highlighted by Teagasc suggests that nutrient recovery systems could help farmers replace part of their purchased nitrogen fertiliser while making better use of nutrients already available on the farm.
Potential financial benefits could include:
- Lower fertiliser purchases.
- Reduced slurry transport costs.
- Improved nutrient utilisation.
- Better returns from anaerobic digestion systems.
- Reduced exposure to fertiliser price volatility.
While these outcomes will vary across farms, they demonstrate that nutrient recovery can support both economic and environmental objectives.
Looking Ahead
RENURE is not a replacement for good nutrient management, nor does it remove the need to comply with Ireland’s environmental regulations. However, it does introduce a new way of managing nitrogen that could help farmers respond to future challenges.
As Ireland considers how to implement the EU framework, RENURE may become another tool that allows farmers to recover more value from existing resources, improve nutrient efficiency, and reduce some of the pressures associated with nitrates derogation.
For farms operating close to regulatory limits, that flexibility could prove just as valuable as the fertiliser itself.
