Nutrient Calculator Tool

Spring has sprung!

If you’re planning a spring fertiliser application on your farm, a free online nutrient calculator can help you work out how much fertiliser each paddock needs!

Input your own soil test results, select the right fertiliser and calculate the application rate needed. The nutrient calculator is a specialised tool for pastures in the high rainfall zone (annual rainfall greater than 600mm) of south-west Western Australia.
