Iowa State University Extension and Outreach has recently released a publication that complements existing extension manure management resources. How to Interpret Your Manure Analysis, PM 3014, explains the value of manure sample analyses that indicate nutrient concentrations. Such analyses help define application rates that increase the potential of manure as a crop nutrient source.
Having manure analyzed is the best way to determine nutrient concentration. This publication explains the numbers producers see in laboratory analysis results and tells how to use those numbers in the nutrient management planning process."
The publication explains how frequently to sample, what tests to request, what the results mean and how to use those results in a nutrient plan. "How to Interpret Your Manure Analysis" also provides examples of lab reports and a list of common conversions.
By viewing the publication online, readers can click on highlighted text and reach Web pages with additional nutrient planning information. The publication can be viewed or downloaded from the ISU Extension Online Store. The print version of the publication can be ordered from the store online, by calling 515-294-5247 or emailing firstname.lastname@example.org.
