Iowa debate: Whose yardstick to measure farm runoff?

With hundreds of millions of dollars at stake in carrying out Iowa's Nutrient Reduction Strategy, which calls for a 45 percent cut in nitrogen and phosphorus levels in waterways, "a new and controversial debate is looming," says the Des Moines Register.
