This study attempted to find the agronmic value and loss of nitrogen from different application methods and timing methods of swine manure.  The areas that were tested were ammonia volatilization, soil inorganic nitrogen levels, and nitrogen uptake and yield for corn. Some of the different application methods were pretilage with aerator, deep or shallow injection, surface applied with the crop in and without the crop in, different rates of nitrogen per hector as well as others methods. The timing was tested by doing experiments in late summer, fall, spring, and side dress. This study found that deep or shallow injecting resulted in virtually no ammonia volatilization, and the aerator treatment had lower emissions than the surface applied treatment. Soil inorganic N was found to be generally similar regardless of manure application method. The study found that manure application method and application timing significantly affected the amount of nitrogen lost by volatilization except under cool wet conditions in which the application method had no effect.
