# Iowa State University Study Can’t Refute that Increased Production Costs and Commensurate Supply Chain Issues Drove Increase in Fertilizer Prices - The Fertilizer Institute

> The Iowa State CARD study, commissioned by the Iowa Attorney General, found insufficient evidence to refute that production costs and supply chain issues were the main cause of 2021-22 fertilizer price increases. The Fertilizer Institute welcomed the finding and listed factors such as the pandemic, energy costs, sanctions and the Russia-Ukraine war.
