Total annual consumption of commercial fertilizer is now more than 45 million metric tons product in the U.S.A. and 4.2 million metric tons product in Canada. Nutrient use per acre of corn stopped increasing in the early 1980's. Nitrogen use per acre for corn has been relatively stable since then, while P and K use has declined. During this same period, corn yields have continued to increase at a rate exceeding 1.5 percent per year. These practices reduce nutrient losses and produce a cropping system that more efficiently utilizes all inputs, including commercial fertilizer.
