Frequently Asked Questions
Do I subtract exported manure from my total N?
YES — exported organic manure (with contracts) is deducted. Enter in the “Nitrogen Exported” box.
Can I include chemical fertiliser in the calculation?
NO — NVZ limit applies only to organic manures (slurry, FYM, poultry). Chemical N is separate.
Will the PDF report be accepted by RPA?
Yes — it includes all required data, date, and clear compliance statement. Farmers use our reports annually.
