Nitrogen (N) is one of the most important element for crop production because it is required by plants in the largest quantity. Depending upon crop species, it may vary from 1-5% of total plant dry matter.  Nitrogen is an integral component of proteins, nucleic acids, chlorophyll, co-enzymes, phytohormones, and metabolites. Atmospheric N, is not readily available to most plants.  The availability of N in soil varies significantly in time and space.  This variability is driven by soil properties such as texture, ph, moisture, and microbial activity. The challenge for precision N management is to account for all available sources of N and synchronize it with the crop N need in all: place, time, and amount. How do we overcome this challenge will be discussed in this presentation with a focus on precision N management.

Biography

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.
