It’s true that livestock manure offers nutrient value to crops and the soil. However, keeping tabs on that offering is a challenge. Now you can access a new software program to help determine nutrient values from all types of manure.

The Manure Nutrient Value Calculator (V1.0) is a spreadsheet program that works with Microsoft Excel 97 (or newer) and uses approximately 265K of space. It is available on floppy disk from the Iowa Pork Industry Center at Iowa State University.

Ken Stalder, assistant animal science professor, and Garland Dahlke, program specialist, developed the program that uses data on available manure, including form, quantity and analysis results, to provide recommendations for any additional commercial fertilizer needs as well as a financial breakdown based on manure and commercial fertilizer values.

“This software asks for information on what form and quantity of manure you’re using and its handling cost,” says Stalder. “You also enter soil and nutrient analysis results, along with the desired application rate and price of commercial fertilizer. The program can tell you how many acres your manure will cover, how much commercial fertilizer you’ll need to apply and the total cost of applying all necessary fertilizer to that specific piece of land.”

He says the Manure Nutrient Value Calculator (V1.0) is easy to use because of the “Tips” and “Help” screens that are built into the program.

While you can view the calculator results on-screen, you also can print a summary of the information, which you can use as you work with neighbors, Extension field specialists, crop consultants and others to develop manure and nutrient-management plans for the operation.
