Fertilizer prices, a new threat
WASHINGTON/WINNIPEG: It powered the Green Revolution and helped save millions from starvation, but now one of the most important tools on the farm is being priced out of reach for many of the world's growers. With food prices soaring and stocks thinning, the world is in need of bumper harvests but once one of most bountiful of commodities, fertilizer, is becoming scarce and expensive. It's estimated that one third of the protein consumed by humans is a result of fertilizer. So high prices and spot shortages are yet another stress on the world's ailing food system.
