A new software program from Iowa State University (ISU) can help determine nutrient values from all types of manure.
The Manure Nutrient Value Calculator is a spreadsheet program that works with Microsoft Excel 95 or newer. It’s available on floppy disk from ISU’s Iowa Pork Industry Center.
ISU Animal Scientist Ken Stalder and program specialist Garland Dahlke developed the software.
“This software asks for information on what form and quantity of manure you’re using and its handling cost,” says Stalder. “You can also enter soil and nutrient analysis results, along with the desired application rate and price of commercial fertilizer, and 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.”
