The volume of global phosphate rock reserves has been widely debated, with some arguing production could ‘peak’ within decades.

Dr. Amit Roy, president and CEO of IFDC, argues that the immediacy of a crisis due to phosphate rock depletion is overstated, pointing to the knock-on effect that rising fertilizer prices have on economically viable reserves. Prices have risen considerably over the past decade, more than doubling to $500 per metric ton between 2007 and 2011, according to World Bank data.
