If your farm land is in a Nitrate Vulnerable Zone (NVZ), [[company/farmwalk|Farmwalk]] helps you meet the strict rules on nitrogen applications - including closed periods, storage requirements, and annual application limits. The NVZ module includes built-in calculators so you can stay compliant without manual spreadsheets.
Adding NVZ to your farm
Go to your farm's Schemes page
Click Add Scheme and select NVZ
Confirm your NVZ designation and affected parcels
Built-in NVZ tools
Your NVZ scheme includes specialist calculators and record-keeping tools:
Nitrogen calculator - Track total N applications against your 170 kg N/ha limit
Storage calculator - Verify your slurry and manure storage meets capacity rules
Closed periods - View and track the closed spreading periods for your land type
Manure inventory - Record manure and slurry volumes produced and moved
Spreading tracker - Log each spreading event with date, field, and volume
Applications - Full history of all nitrogen applications by parcel
History chart - Visual trend of N applications over time
Reports and tasks
Generate NVZ compliance reports for your records. Any outstanding actions can be tracked as tasks.
Tips
Log spreading events promptly - NVZ records must be kept for at least 5 years
Check closed period dates before each spreading operation
Use the nitrogen calculator before each application to avoid exceeding your annual limit
