Nitrogen Use Efficiency, Facts and FiguresThe USA produces 367,936,410 Mt of cereal grain, which is over 1/10 the world total of 2,242,997,310 (2005)

The USA consumes 6,555,660 Mt of N Fertilizer for Cereal Grain Production Annually

FACT: Nitrogen Use Efficiency for Cereal Production in the World is 33%

>94,000,000 Mg of N fertilizer are consumed each year the world, 60% of which is used for cereal production

A
1% increase in NUE in the WORLD would be worth $1,113,208,507 (2005)

20% increase in cereal NUE worth >$10,811,044,050 TODAY
(value gets smaller as % increase goes up, due to decreasing size of loss)

2005: 1 english ton N fertilizer ($350)
2005: 1 metric ton N fertilizer ($836) (actual N)


94,000,000 Metric tons of N Fertilizer used in the world (2005)
60% of N fertilizers used in cereals = 56,400,000 Metric tons

 

N fertilizer savings per year for each 1% increase in NUE (same yield) 549,595 64,261
2007 value using $650/metric Ton of actual N     $357,236,591 $41,769,907
2007 value using $650/metric Ton of actual N (20% increase) $7,144,731,815 $835,398,135
