Iowa Learning Farms, AgVantage FS Host Field Day Near Sumner
AMES, Iowa — Iowa Learning Farms, AgVantage FS and Iowa State University Extension and Outreach will host a field day at the AgVantage FS test plot located west of Sumner, Iowa, beginning at 10 a.m. on Wednesday, June 27. The field day will focus on in-season urea nitrogen fertilizer application with GreenSeeker technology and its impact on corn and water quality.
The field day will include presentations by John Sawyer and Dan Barker, ISU Extension and Outreach agronomists. They will highlight corn yield results from 2011 on-farm trials with in-season urea fertilizer application and potential for the crop management practice.
GreenSeeker precision agriculture specialist Russ Linhart will address questions about GreenSeeker technology, which uses sensors on the fertilizer applicator equipment to assess corn leaf greenness. Corn plants that are less green may not have sufficient nitrogen to optimize plant growth and resulting yield. The GreenSeeker sensors and variable-rate application technology fine-tunes the amount of urea nitrogen applied, targeting these nitrogen-deficient plants. This technology will be demonstrated at the field day.
GROWMARK field sales agronomist John Grandin will discuss nitrogen management as a system. ISU Extension and Outreach water quality engineer Matt Helmers will demonstrate the ILF Conservation Station rainfall simulator and discuss the relationship between fine-tuning nitrogen application rates and timing and the potential to reduce nitrate leaching into nearby streams and rivers.
The field day includes a complimentary lunch. The event is free and the public is invited to attend. The AgVantage FS test plot is located on at the intersection of Highway 93 and Whitetail Ave. just west of Sumner.
