  • 4. 2019 cropping year in review: Soils, crops and weather (1.0 CM)

    Sotirios Archontoulis, associate professor, Agronomy, Iowa State University, Ames, IA

    I will present data on corn and soybean yields from Iowa field experiments as well as regional scale yield estimates for Iowa, Illinois, and Indiana. Then I will synthesize data on soil water, soil nitrogen, weather, management with simulation modeling to explain the 2019 yield levels across scales.
    Session H - Thursday, 8:00 AM - 8:50 AM
    Session I - Thursday, 9:00 AM - 9:50 AM

  • 5. Harvest crop quality 2019... Another year of new experiences (1.0 CM)

    Charles Hurburgh, professor, Agricultural and Biosystems Engineering and professor in charge, Iowa Grain Quality Initiative, Iowa State University, Ames, IA; Erin Bowers, associate scientist, Agricultural and Biosystems Engineering, Iowa State University, Ames, IA

    From start to finish, the 2019 growing season continued the recent trends of extremes and rapid changes, which made outcomes very hard to forecast in advance. This presentation will summarize the season and its results from a crop quality perspective. The authors will offer management recommendations for the increasingly longer term storage periods that market changes have created.
    Session F - Wednesday, 3:10 PM - 4:00 PM
    Session G - Wednesday, 4:10 PM - 5:00 PM

  • 6. Understanding post-maturity in-field grain dry down (1.0 CM)

    Mark Licht, assistant professor and Extension cropping systems specialist, Agronomy, Iowa State University, Ames, IA

    When corn and soybean maturity is delayed there is also a decline in the amount of grain dry down that can occur in the field. The old rules of thumb are vague and less than precise. A recent research project evaluated the genotype by environment interactions to develop a grain dry down calculator to estimate post maturity in-field grain drydown.
    Session F - Wednesday, 3:10 PM - 4:00 PM
    Session G - Wednesday, 4:10 PM - 5:00 PM

  • 7. Agronomic implications of new planter technologies (1.0 CM)

    Péter Kovács, assistant professor, Precision Ag Cropping Systems, South Dakota State University, Brookings, SD

    New developments in farm machinery has also impacted planter technologies in the last few years that is available for producers. Results from replicated field research trials which involved high-speed or multi-hybrid planter technologies will be discussed. The presentation will also cover the potential implications for crop management practices of these new technologies.
    Session B - Wednesday, 10:00 AM - 10:50 AM
    Session C - Wednesday, 11:00 AM - 11:50 AM

  • 8. Quality of digital aerial imagery and implications for various uses in agriculture (1.0 CM)

    Peter Kyveryga, director of analytics, Iowa Soybean Association, Ankeny, IA; Aaron Prestholt, Agricultural Data Analyst, Iowa Soybean Association, Ankeny, IA

    Agriculture is seeing a significant surge in different digital aerial and drone imagery technologies. Quality of imagery often dictates its utility. For the last 4 years, we worked with more 15 imagery providers to study this topic. This presentation will emphasize, using examples, the implications of various image related issues (e.g., spatial accuracy, band-to-band registration, mosaicking and calibration quality). Ultimately, an understanding of these image quality differences will have an impact on the utility for visual assessment and quantitative measurements by crop scouts, agronomists and agricultural researchers alike.
    Session H - Thursday, 8:00 AM - 8:50 AM
    Session I - Thursday, 9:00 AM - 9:50 AM

  • 9. Is Cannabis really the right crop for you? (1.0 CM)

    Robin Pruisner, state entomologist and ag security coordinator, Iowa Department of Agriculture & Land Stewardship, Ankeny, IA

    Iowa is abuzz with excitement about hemp becoming the best cash crop in Iowa. This session will explain the various hemp crops (know before you grow!), federal and state regulations, and discuss the challenges and risks that need to be carefully considered before diving in to hemp in Iowa in 2020.
    Session J - Thursday, 10:10 AM - 11:00 AM
    Session K - Thursday, 11:10 AM - 12:00 PM

  • 10. Interactive web-based tool for profitable decision making from on-farm trials (1.0 CM)

    Peter Kyveryga, director of analytics, Iowa Soybean Association, Ankeny, IA; Suzanne Fey, Data Analyst, Iowa Soybean Association, Ankeny, IA

    This presentation will demonstrate the use of the web-based Interactive Summaries of On-Farm Strip Trials (ISOFAST) tool developed by Iowa State University and Iowa Soybean Association. We will present how to make economic decisions using dynamic and interactive summaries generated from 15 years of historical on-farm replicated strip trials. The tool is perfect for farmers and crop consultants who want to know the odds of break-even crop response for a variety of field management practices using different input costs and grain price scenarios for different parts of Iowa, under different weather conditions.

    Session M - Thursday, 2:00 PM - 2:50 PM

  • 11. Cover crop interseeding: A new pathway for enhanced adoption (1.0 CM)

    M. Scott Wells, assistant professor, Agronomy and Plant Genetics, University of Minnesota, St Paul, MN

    The lecture frames the primary externalities associated with annual row crop production in the Upper Midwest and offers potential plant-based technologies (i.e., cover crops and new cropping systems) with the promise of improved sustainability. Topics covered include but not limited to interseeding cover crops in vegetative and reproductive stages in corn and soybean and a new systems approach to dealing with the corn/soybean externalities. No prior knowledge required. I will discuss the potential limitations and future research and opportunities.
    Session J - Thursday, 10:10 AM - 11:00 AM
