PRINT VERSION (pdf) Download the Fall 2007 issue of Iowa Manure Matters - Odor and Nutrient Management Newsletter in pdf format.

Do you know how much manure you apply? The following photos represent five different rates of solid beef manure applied to cornstalk residue.  Can you guess the rates? The manure was hand-applied to the plots on Aug. 21, 2006 as part of the field demonstration activities at the 2006 Manure Management Clinic. Answers appear at the bottom of the page. 

For more information on solid manure calibration and uniformity of distribution please see Iowa State University Extension Publication PM 1941 Calibration and Uniformity of Solid Manure Spreaders. This publication can be ordered through any ISU Extension county office or online at https://www.extension.iastate.edu/store/ .
