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.

Dr. Raj Khosla is a Robert Gardner Professor of Precision Agriculture at Colorado State University. His main research focus has been on management of in-field soil and crop variability using geo-spatial technologies for precision management of crop-inputs. He has generated many discoveries in precision agriculture, most widely recognized among them is the innovative technique of quantifying variability of spatially diverse soils using satellite based remote-sensing to create management zones. Most recently, he was recognized with the Werner L. Nelson Award for Diagnosis of Yield-Limiting Factors by American Society of Agronomy. Previously, in 2015, he was recognized as the “Precision Ag Educator of the Year”, a national honor bestowed by the agricultural industry and in 2012, he was named the Jefferson Science Fellow by the National Academy of Sciences. Previously, he has served two 2-yr terms on NASA’s US “Presidential Advisory Board on Positioning, Navigation and Timing”.

He is a Fellow of the American Society of Agronomy; Soil Science Society of America; Soil and Water Conservation Society; and Honorary Life Fellow of International Society of Precision Agriculture.

He is the Founder and Founding-President of the International Society of Precision Agriculture.
