Facts and Figures Concerning Nitrogen Use Efficiency

Facts and Figures Concerning Nitrogen Use Efficiency
Precision Sensing Solutions for Improved NUE in Corn and Wheat Production Systems

The 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/yr, each 1% increase in NUE (same yield)
