Variable rate fertilizer applications have been used for many years. How may new sensor technology, advances in integrating map data from several sources, and application technology affect the current applications in the field. How can CCAs take advantage of these advances to assist producers to apply nutrients for minimizing environmental losses while optimizing plant response?

Speaker Information:
Dr. Dave Franzen 
Professor of Soil Science and Extension Soil Specialist 
North Dakota State University 

Dave Franzen is a Professor of Soil Science and Extension Soil Specialist at North Dakota State University. He is an alumnus of the University of Illinois, with a BS (1975), an MS in Soil Fertility (1976), and a PhD in Soil Chemistry (1993). He was employed for 18 years as agronomist/manager at retail fertilizer chain in Illinois, and became the North Dakota State University Extension Soil Specialist in 1994. Dave has conducted extensive research in soil sampling strategies for variable-rate nutrient management, into the use of satellite imagery as a predictive tool of in-season N requirements of several crops, and the use of ground-based active-optical sensors to direct in-season N requirements of those crops. Most recently, he published an NDSU Extension circular with algorithms for use in directing in-season N application to corn in North Dakota using two active-optical sensors in different soils and tillage systems at two different corn growth stages.
