- Nitrogen (N) application to agricultural land has increased
steeply in recent decades.
- Pakistan was among the top four in terms of N use but had low
mean yields, with the lowest NUE and highest N surplus.
- During 1961–2014 in Pakistan, N fertilizer use, and N surplus
grew at a much faster pace than mean yields; however, nitrogen
use efficiency (NUE) continued to decline.
