Analysis

Yemen recorded 27.8% for nitrogen use efficiency in 2014. That is the lowest value across all 54 years on record.

Compared with earlier readings it is down 29.5% on the previous year and down 23.7% over ten years.

Over the whole period, nitrogen use efficiency in Yemen peaked at 164.5% in 1965 and was at its lowest, 27.8%, in 2014.

That places Yemen 146th out of 205 countries with data for 2014, putting it in the middle of the range.

The series is highly variable year to year, so single readings are best treated with caution.
