28 December 2011 - Planning crop nutrition for the coming season starts with looking back at what the previous crop removed. Across Eastern Canada and the Northeastern USA, crop yields varied considerably last year. The following table provides nutrient removal estimates for the average crop yields in a few selected states and provinces. Consider soil test levels to help decide how much to replenish!
