Dairy Nitrogen Fertiliser Advisor Tool

Is your N fertiliser application profitable for your current grazing rotation? Check your thinking against predicted pasture responses determined from nearly 6,000 nitrogen fertiliser experiments undertaken across southern temperate Australia over the past 40 years.

Select your season and region for the current rotation

Select your most likely pre and post-grazing dry mass for the prevailing conditions and your typical N application

Estimate your 'as spread' cost of urea and the 'equivalent market value' of extra pasture consumed
