Because there are significant differences in the uptake of nutrients by different crops,
their impact on fertilizer consumption could be higher for certain crops than for others
(Figure 2).

According to estimates of the IFA (IFA - FUBC assessment 2010) nitrogen applied to
cereals, amounting up to 57.5 Mt, represents 55.2% of the global N-fertilizer consumption in
2010-11 (18.1% wheat, 16.8% maize, 15.4% rice, 4.8% other cereals). Oil crops contributed
7.3%, cotton 4.3%, sugar crops 3.5% and root & tubers 2.8%. Fruits and vegetables
accounted 14.9% of the total, and other crops for 12.0%.
