Analysis
Seychelles recorded 16.7% for nitrogen use efficiency in 2014.
Compared with earlier readings it is up 46.4% on the previous year and up 56.8% over ten years.
Over the whole period, nitrogen use efficiency in Seychelles peaked at 204.2% in 1964 and was at its lowest, 6.0%, in 1982.
Seychelles ranks 170th of 205 countries on this measure, 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.
