AMES, Iowa – The Iowa State University Dairy Farm will host the in-season manure application field day on June 14. Solving nutrient water quality issues originating from agriculture requires the development of innovative strategies that are climate smart. Iowa State researchers are teaming up with industry partners for developing and demonstrating in-season manure and nutrient management strategy.

“Manure application past the V4 vegetative growth stage of corn has not been done mainly due to wet weather concerns and compaction issues,” said Kapil Arora, field agricultural engineer with Iowa State University Extension and Outreach. “As corn grows taller, higher clearance machines are required to apply manure past V4 corn growth stage.”

Manure application in standing corn.The field day will demonstrate one such technology, Agrometer SDS 8000, which enables manure application up to 3 feet corn plant height. The field day flyer explains the activities for the day. The program will begin at 11:30 a.m. with a free lunch for registered participants. Discussions will be held on the topics of in-season manure application strategy, corn plant nutrient needs and supply, economics of in-season manure application, and what it all means for overall on-farm manure management. Field demonstration will be held after the presentations and will conclude by 3 p.m.

Commercial and confinement manure applicators, agency staff involved in manure management, manure planners and consultants, watershed coordinators and other interested stakeholders are encouraged to attend. The field day is a collaborative effort between the Iowa Pork Producers Association, Agrometer and Iowa State University Extension and Outreach.  

Registration is required. Register by June 10 to ensure a free meal. Call the ISU Extension and Outreach Story County office at 515-337-1601 or email xstory@iastate.edu.
