Soaring fertilizer prices put global food security at risk (Axios) 

Axios published an article that the rolling crises of the past few years rendered visible so many vital commodities that plenty of us never gave much thought — nickel, silicon chips, lumber. The latest entrant into this camp: Fertilizer. Skyrocketing fertilizer costs — like those made from nitrogen, phosphorus, and potassium (NPK) — are driving up food prices and, worse, threatening food security around the globe. Prices for NPK were up 125 percent in January from a year before, and rose another 17 percent from the beginning of the year to March, according to data compiled by IFPRI. The article also published a figure by IFPRI on the “World fertilizer price index.”
