SWAT Agronomy Insights with Dr. Dave Franzen

About this event

The change in North Dakota crop choices from dominant small grains to more corn and soybean resulted in drastic reductions in soil test potassium (K) values. Potassium rate studies on corn were conducted to determine whether the ‘old’ K recommendations were predictive, and we found that they were not about half the time.

The clay species at the K rate sites were examined based on work from D. Sparks at University of Delaware. During this SWAT Agronomy Insights webinar, Dr. Dave Franzen will discuss what was found in these examinations and why it’s important to factor in clay species when considering the need for tillage and the type required.

Dave Franzen received a BS in Forest Soils from the University of Illinois, followed by an MS in Soil Fertility and a PhD in Soil Chemistry. His research has included whole-field studies in site-specific nutrient management, including the development of zone soil sampling techniques. He has also developed algorithms for the use of active-optical and height sensors for small grains, corns, sunflower and sugarbeet.

CCAs: 1 CEU in nutrient management.
