Farming in an NVZ can sometimes prove challenging. Certain operations will be governed by regulations, including demonstrating adequate slurry storage capacity and restrictions over times of year when organic manures can be applied to land.

My farm is in an NVZ, what must I do?
Do not apply more N than your crops require – there are limits within NVZs on the amount of N from livestock manure and manufactured N fertiliser you can use
Plan your N use before making any applications
Do not exceed a loading of 170kg total N content per ha per year (N/ha/year) from livestock manures averaged over the total area of your farm. This includes manure applied by spreading and manure deposited by grazing animals
Comply with closed periods for spreading organic manures and manufactured N fertiliser
Provide adequate storage capacity for livestock manures. You should have sufficient storage in place by 1 Jan 2012 at the latest
Requirements are 5monhts slurry storage for cattle slurry and 6 months for pig slurry
Keep records of the N applied to each of your fields and some records and calculations relating to your farm as a whole. You must keep all records for at least 5 years
Produce a risk map for any land where you intend to spread organic manures
If you are a grassland based system, with at least 80% of your fields to grass you may be elgible to apply for a derogation from the 170kgN/ha/year to 250kgN/ha/year
** In NVZ leaflet 3, table 8 the livestock manure efficiencies are to be increased for cattle slurry from 35% to 40% and for pig slurry from 45% to 50% for 1st January 2014.
