Global wheat production and fertilizer use

S Phillips and R Norton

Global wheat production has risen over two and a half times since 1960 as the result of better farming practices, improved cultivars, and balanced nutrition. At the same time, fertilizer use in all agriculture has risen 4.3 times to keep up with growing food demand. It is estimated that growers use around 15% of the fertilizer consumed to produce the current 647 M t of wheat grain.
