Nitrogen use efficiency in Equatorial Guinea, 1961–2014
Source: Lassaletta et al. (2014) – processed by Our World in Data. Measured in %.
Analysis
Equatorial Guinea recorded 506.2% for nitrogen use efficiency in 2014. That is the highest value across all 54 years on record.
Compared with earlier readings it is up 232.3% on the previous year and up 302.8% over ten years.
Over the whole period, nitrogen use efficiency in Equatorial Guinea peaked at 506.2% in 2014 and was at its lowest, 40.4%, in 1972.
That places Equatorial Guinea 2nd out of 205 countries with data for 2014, putting it in the top 10%.
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.
