The webinar is part of a free series, hosted by ILF, through Adobe Connect. The series is held on the third Wednesday of each month. A computer with Internet access is all that is needed to participate.
Barker’s presentation will discuss field research trials and on-farm demonstrations using remote sensing technolgies (active canopy sensors) in order to vary application of in-season nitrogen fertilizer in corn. He will discuss total amounts of nitrogen fertilizer applied, efficiency of nitrogen rates and timings, and yield benefits with sensor nitrogen strategies.  
Daniel Barker, Ph.D., is an assistant scientist in the Iowa State University agronomy department. He has research and extension responsibilities in soil fertility, nutrient management and remote sensing.
