Milking platform: means that area devoted to feeding cows on a daily basis during the milking season.

Nitrogen Reference Point: The nitrogen loss number (units of kgN/ha/year) that is derived from an OVERSEER® use protocol compliant OVERSEER® file that describes the property or farm enterprise and farm practices in an agreed year or years developed by a Certified Farm Nutrient Advisor, using the current version of the OVERSEER® model (or another model approved by the Council) for the property or enterprise at the "reference" point in time.
