Nitrate quick test mass balance tool (calculator)

This tool is a simple calculator to convert quick test strip results into an estimate of the crop's demand for nitrogen. N supply estimates are automatically calculated from the input information.

This tool should be used alongside the 'Quick test mass balance user guide' which may downloaded from this website (keyword search: nitrate), or from the FAR website (www.far.org.nz).
