As part of this decommissioning the Nitrate Vulnerable Zones data will be removed on Thursday 27 July

The 2017 Nitrate Vulnerable Zones can be found on Defra's Magic Map from the Wednesday 5 July

The 2017 Nitrate Vulnerable Zones data is available to download under an Open Government Licence from DATA.GOV.UK 

 

What are Nitrate Vulnerable Zones

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.

Key to understanding the Nitrate Vulnerable Zones map:

2017 Nitrate Vulnerable Zones

The 2017 Nitrate Vulnerable Zones are the NVZ boundaries which apply from 2017.

  Surface Waters - areas of land that drain into a freshwater water body which has or could have is action is not taken, a nitrate concentration greater than 50mg/l

  Groundwater - water held underground in the soil or in pores and crevices in rock, which has or could have if action is not taken, a nitrate concentration greater than 50mg/l

  Eutropic Waters - bodies of water, mainly lakes and estuaries, that are or may become enriched by nitrogen compounds which cause a growth of algae and other plant life that unbalances the quality of the water and to organisms present in the water .

The Nitrate Vulnerable Zones are the zones which applied from 1 January 2013 to 31 December 2016

  Surface Waters - areas of land that drain into a freshwater water body which has or could have is action is not taken, a nitrate concentration greater than 50mg/l

Guidance for farmers in Nitrate Vulnerable Zones (NVZs)

Decision Notice Batch

Notices of farms inclusion within a proposed NVZ with be posted to farmers in 3 groups called tranches.

  Tranche 1 - farms that are affected by a proposed NVZ which are within the Tranche 1 area will receive their notifications from the 3rd January 2017

  Tranche 2 - farms that are affected by a proposed NVZ which are within the Tranche 2 area will receive their notification from the 23rd January.

 Tranche 3 - farms that are affected by a proposed NVZ which are within the Tranche 2 area will receive their notification from the 20th February.
