Analysis
In 2014, nitrogen use efficiency in New Zealand stood at 5.2%. That is the lowest value across all 54 years on record.
That represents a change of down 49.3% on the previous year and down 47.7% over ten years.
Over the whole period, nitrogen use efficiency in New Zealand peaked at 26.7% in 1978 and was at its lowest, 5.2%, in 2014.
That places New Zealand 196th out of 205 countries with data for 2014, putting it in the bottom quarter.
The long-run direction has been consistently falling across the 54 years of available data.

About this data
Nitrogen use efficiency (NUE) is the ratio between nitrogen inputs and output. A NUE of 40% means that only 40% of nitrogen inputs are converted into nitrogen in the form of crops.
