Using fertiliser

Organic or manufactured nitrogen fertilisers that you use on your land can pollute surface and ground waters.

What you must do

Store and apply fertilisers safely

Make sure you comply with regulations on storing and applying fertilisers by checking our guidance on chemical and man-made fertilisers

Check if you need to comply with spreading limits for manure and fertilisers

If your land is in a nitrate vulnerable zone (NVZ) Scotland you may have to comply with limits on the amount of livestock manure and manufactured fertilisers you can spread on your land. These limits apply to all land in Northern Ireland.

Read our guidance on NVZs for more information and to find out if you are in an NVZ.
