Today on Advancing Nitrogen Smart we ask an unusual question: What is manure, really? We all know manure is made of the liquids and solids that pass through an animal's digestive system, but what has to happen for manure to become usable? Is all manure created equal, or do differences in animal type - and their feed - result in manure with variable nutrient values? How do factors like handling, storage and animal bedding impact available nutrients in manure? What are some of the long-term benefits of manure application? Is there an optimal time of year to apply manure? Brad Carlson and Melissa Wilson answer these questions and many more on this 39th episode of the Advancing Nitrogen Smart podcast.

Guests:

• Brad Carlson, Extension educator (Mankato)
• Melissa Wilson, Extension manure nutrient management specialist (St. Paul)
