CHECK IT: Careful planning goes into applying manure uniformly. Application rate, operating pressure, outlet location and discharge hose arrangement are important operating factors that govern how uniformly a manifold distributes manure across the toolbar points.Kapil Arora

Uniform liquid manure distribution across the application toolbar is important for proper use of nutrients. Uniform distribution of manure across the toolbar swath ensures minimal variability among application points. Uneven manure application, especially under low application rates, can potentially lead to uneven response in crop growth.

Iowa State University Extension has scheduled four field days to help manure applicators better understand manure distribution, calibration and the value of manure. Checking a flowmeter’s calibration is important to achieve accurate application rates in the field. Understanding the value of manure can help producers to use nutrients appropriately, leading to better manure management for their livestock operations.

“We want to remind producers to check their manure application equipment to make the most out of the distribution manifold, as the cost to supplement nutrients with commercial fertilizers can be expensive,” says Kapil Arora, ag engineering specialist with ISU Extension.

Speakers to share their knowledge
Speakers for the Manure Distribution and Calibration field days include Dan Andersen, assistant professor and ag engineering specialist with ISU Extension and coordinator of the Iowa Manure Management Action Group. Also speaking at the field days will be Kapil Arora, Greg Brenneman, Kris Kohl and Shawn Shouse, all ag engineering specialists. ISU Extension agronomists Mark Johnson, Mike Witt, Joel DeJong, Paul Kassel, Meghan Anderson and Rebecca Vittetoe will also be present at the field days.

The program for each field day will begin at 11:30 a.m. with registration, followed by a free lunch at noon. Presentations and demonstrations will begin at 1 p.m. and will cover manifold distribution, flowmeter verification and value of manure as fertilizer. Information on manifold distribution, collected through research funded partly by the National Pork Board, will also be shared.
