World Fertilizer Price Index 1960 to 2014 rose unevenly from 65 to 107
Global fertilizer prices have fluctuated since 1960. They started at $65 in 1960, were fairly stable for a decade, then increased nearly threefold to $182 in 1974. Two years later the price index dipped back down to $59, and then slowly increased more than three-fold to a peak value of $196 in 2008. Since then, the global fertilizer price index has decreased to $107. This index uses the 2005 US dollar value as a base value. World Bank collects commodity price data annually... and publishes "pink sheets" with the price indices. This data came from a larger excel worksheet published by the World Bank. To find it, go to the World Bank's Commodity Markets page via this link (http://econ.worldbank.org/WBSITE/EXTERNAL/EXTDEC/EXTDECPROSPECTS/0,,cont...), and at the bottom of the page is a list of featured products. One of them, in the lower left corner, is labeled "Historical Data." Then on the 4th tab/page called "Annual Indices Real" is a column of fertilizer price index (column M) with annual updates from 1960-2014.
