Field day: Sidedressing for water quality

By Staff | Jun 26, 2014

CLARION – Iowa Soybean Association experts and others will help farmers learn how to improve water quality and nutrient management at a nitrogen sidedressing field day at 10 a.m. on Tuesday near Clarion.

The Boone River Nutrient Management Initiative event will begin with registration at 9:30 a.m. at North Central Co-op’s test plot, just north of Clarion near the intersection of county roads R38 and C20.

Pre-registration is suggested, but not required. Send RSVPs to agronomy@hagie.com.

Farmers in the Boone River Watershed are targeted for this event There is no admission cost to this event, sponsored by Hagie Manufacturing in Clarion.

ISA’s On-Farm Network and its Environmental Programs and Services team will discuss replicated strip trial results focused on nitrogen timing and rate adjustments.

Farmers will also learn how they can participate in On-Farm Network studies, stalk-nitrate testing and water quality monitoring.

“This field day will provide farmers information about nitrogen timing and rates,” said Adam Kiel, ISA’s Environmental Programs and Services state water resources manager, “a cornerstone of the Iowa Nutrient Reduction Strategy.”

Other speakers and topics include:

A). Sarah Caldwell, a Dow sales representative, on the importance of nitrogen stabilization.

B). John Holmes, a North Central Co-op agronomist, on late-spring nitrate test sampling and interpretation.

C). Bruce Voigts and Emily Funk, of the Natural Resources Conservation Service, offering updates on local water quality and soil conservation efforts.

The Boone River initiative is one of eight watershed demonstration projects in Iowa to receive more than $12 million in funding through the Iowa Water Quality Initiative and matching contributions for the next three years to support water quality improvements.

Soil and Water Conservation Districts in Wright, Humboldt and Kossuth counties received more than $1.8 million in public support and from industry partners to provide educational programs and cost-share funds to farmers to try nutrient reduction practices outlined in the Iowa Nutrient Reduction Strategy.

Hagie, which manufactures self-propelled sprayers and equipment, will conduct demonstrations – weather permitting – featuring a nitrogen toolbar.

Rachel Halbach, a Hagie agronomist, said the event is geared for farmers interested in enhancing their nitrogen management plan and protecting the environment.

Topics will revolve around nitrogen use efficiency in corn and how growers can increase yield without adding more fertilizer.

“When nitrogen is timed to crop uptake,” Halbach said, “rates can be adjusted and risk of loss is reduced. And, a yield response of 10 to 15 bushels per acre is possible.”
