10. What assessment has the Welsh Government made of the impact of nitrate vulnerable zones? OQ57004

The designation of nitrate vulnerable zones was a requirement of the EU nitrates directive, and the effectiveness of the NVZ designation was assessed as part of our commitment. Natural Resources Wales review NVZ designation on a regular basis to determine areas for new designation, continued designation or de-designation.

Thank you, Minister. The NVZs in Wales limit agriculturalists to spread no more than 170 kg of nitrates per hectare, whilst the zones in other nations enable farmers to spread up to 250 kg per hectare. This limitation means that slurry is held back and can't be spread and causes difficulties to farmers, or it will do so. Can you explain, therefore, what the rationale of the Welsh Government is for limiting to 170 kg here, whilst other places limit it to 250 kg?

We no longer have bespoke designated nitrate vulnerable zones in Wales, as you're aware, and on 27 January this year, I introduced the Water Resources (Control of Agricultural Pollution)(Wales) Regulations 2021, and as you know, those initial measures came into force on 1 April. Those regulations revoked and replaced the Nitrate Pollution Prevention (Wales) Regulations 2013, which obviously previously designated NVZs, and as you know, at the moment, permission has been granted for those regulations to be reviewed by the courts.

I thank the Minister.
