Note: Recovery efficiency is the average of recovery efficiencies from each observation. A 100-percent recovery is achieved when the amount of phostphate removed from a field is equal to the amount of phosphate applied to the field. Efficiency above 100 percent indicates more phosphate is removed than applied.
