Synthetic fertilizers expanded five-and-a-half fold since 1961; Nitrogen fertilizer expanded nine-fold

July 15, 2015

Total NPK consumption for the world (in thousands of tonnes of nutrients): 1961-2011
2011=176,173.8
1961=31,658.2
Math:
176173.8/31658.2=5.56
~ five-and-a-half-fold increase in world consumption of total fertilizer

 

Total Nitrogen consumption for the world (in thousands of tonnes of nutrients)1961-2011
2011=108,159.7
1961=11,784.4
Math:
108159.7/11,784.4=9.17
~ nine-fold increase in world consumption of nitrogen fertilizer
