In the News Feature 'The Disappearing Nutrient' ( Nature 461, 716–718; 2009), Amit Roy was misquoted as saying there was a possibility of "market manipulation" with phosphates. His full quote was: "The biggest challenge is that concentration of supply is only in a few hands and there is the possibility of manipulation of supply, demand and prices." Roy did not mean to imply that there is a possibility of market collusion.
