If your farm sits in a Nitrate Vulnerable Zone, the NVZ scheme page in [[company/farmwalk|Farmwalk]] gives you the calculators, planners and trackers you need to demonstrate compliance with the rules on nitrogen, manure storage and spreading.
Opening NVZ tools
From the farm choose Schemes and open your NVZ agreement. The detail page has nine tabs.
Nitrogen tab
The Nitrogen calculator tracks nitrogen use against the limit. It shows nitrogen per hectare and the percentage of the allowable maximum used so far. Save calculations to refresh your live status.
Storage tab
The Storage tab is the manure storage capacity calculator. Enter your storage facilities and livestock numbers; the calculator works out how many months of capacity you have and whether it meets the regulatory [[company/minimum|minimum]].
Closed Periods tab
A reference for the application embargo dates. Spreading isn't allowed during these windows - the page makes the dates easy to find.
Manure Inventory tab
A [[company/tally|tally]] of livestock by category, with their nitrogen contribution. Combined with the Nitrogen tab, this is your annual nitrogen balance.
Spreading Tracker and Applications
Spreading Tracker - log applications by field, including amounts and dates
Applications - the parcel-level spreading log used during inspections
History tab
A year-on-year nitrogen trend chart so you can see how your inputs are evolving and spot upward drift before it becomes a compliance issue.
Reports and Tasks
The Reports tab generates an evidence pack for inspectors. The Tasks tab lists farming work tied to NVZ - such as testing soils before applications.
Tips
Keep livestock numbers up to date in Farming > Livestock - the Manure Inventory feeds off them
Save Nitrogen calculations after every application so the dashboard reflects reality
Generate a History snapshot at the end of each year and store it in the vault
