Information for farmers. Find out if the land you farm is in a nitrate vulnerable zone, and what you need to do if it is.
European Commission nitrates directive
The European Commission (EC) nitrates directive requires areas of land that drain into waters polluted by nitrates to be designated as Nitrate Vulnerable Zones (NVZs). Farmers with land in NVZs have to follow mandatory rules to tackle nitrate loss from agriculture.
The Nitrates Directive is implemented by separate regulations in England and Wales. We are responsible for enforcing and assessing farmers' compliance with these regulations.
We have position statements on compliance assessment and enforcement for Nitrate Vulnerable Zones (NVZs). We have both an over-arching position statement and a specific position statement on enforcement of slurry storage provisions in England and Wales.
NVZs in England
The regulations that implement the Nitrates Directive in England are called the Nitrate Pollution Prevention Regulations 2008 (as amended). These came into force on 1 January 2009, though some parts will be phased in. NVZs now cover 62 per cent of England.
If you farm in England and want to check whether your fields are in an NVZ, you can do this using the detailed maps that are available on Defra's website.
NVZs in Wales
The equivalent regulations in Wales are the Nitrate Pollution Prevention (Wales) Regulations 2008 (as amended), which became law on 1 January 2009. The rules that Welsh farmers must comply with are effectively the same as those in England.
If you farm in Wales and want to check whether your fields are in an NVZ, maps are available on the Welsh Assembly Government (WAG) website. You can also see printed versions at WAG and local authority offices. Approximately two per cent of Wales is designated as NVZ.
