Analysis
In 2014, nitrogen use efficiency in Singapore stood at 2.2%.
The figure is up 18.6% on the previous year and up 561.7% over ten years.
Over the whole period, nitrogen use efficiency in Singapore peaked at 2.5% in 1971 and was at its lowest, 0.2%, in 1994.
That places Singapore 199th out of 205 countries with data for 2014, putting it in the bottom quarter.
The series is highly variable year to year, so single readings are best treated with caution.

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.
