Nitrogen holds the first rank among all essential nutrients applied to the crops worldwide. The invention of synthetic Nitrogen fertilizer over a century back (early 1900s) led to dramatic increase in grain yields and global green-revolution. Yet after a >100 years of progress we haven’t attained the level of 50% global nitrogen use efficiency. I cannot think of any other operation or process in agricultural industry that tolerates 50% or lower efficiency rates. We have long ways to go in achieving 5-R Precision Stewardship. What would it take? Can data-driven nitrogen management be the solution? This presentation will provide a holistic approach to Past, Present, and the Future of Nitrogen management.
