Analysis
The most recent figure for nitrogen use efficiency in Puerto Rico is 7.5%, measured in 2014.
That represents a change of up 48.7% on the previous year and up 2.3% over ten years.
Over the whole period, nitrogen use efficiency in Puerto Rico peaked at 58.0% in 1961 and was at its lowest, 4.8%, in 1999.
That places Puerto Rico 187th 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.
