Manure Nutrient Value Software Now Available from Iowa Pork Industry Center


By Ken Stalder, Department of Animal Science

Livestock producers and other interested individuals can use a new software program to help determine the value of nutrients found in all types of manure. The Manure Nutrient Value Calculator (V1.0) is a spreadsheet program that works with Microsoft ® Excel 95 or newer and uses approximately 265 K of space. It is available from the Iowa Pork Industry Center (IPIC) at Iowa State University.

Ken Stalder, assistant professor, Animal Science and Garland Dahlke, assistant scientist, Animal Science, developed a program that uses data on available manure including form, quantity and analysis results. The program determines the value of manure used on the farm or that could be sold to an area crop producer and assists with the determining the remaining commercial fertilizer needs.

This software asks for information on what form and quantity of manure you're using and its handling cost. By entering soil and nutrient analysis results, along with the desired application rate and price of commercial fertilizer, the program calculates how many acres your manure will cover (based on nitrogen or phosphorus needs), how much commercial fertilizer you'll need to apply and the total cost of applying all necessary fertilizer.

The Manure Nutrient Value Calculator (V1.0) has many tips and help screens that are built into the program making the program easy to use. The comment and tip boxes are located throughout the program to help users understand where to enter specific inputs and use the spreadsheet itself. The program requires users to enable macros in Excel.

In addition to seeing calculator results on-screen, users also may print a summary of the information from the program, which can be used by producers as they work with neighbors, ISU Extension field specialists, crop consultants and others to develop manure and nutrient management plans for their operations.

To find out more about the Manure Nutrient Value Calculator (V1.0) software or to order a copy, contact Stalder at the IPIC at (515) 294-4683 or in Iowa , (800) 808-7675.
