The objectives of the 2005 nitrogen (N) source study were to compare the turf response and N release rates of various experimental fertilizer products being proposed for marketing to a number of industry standards, such as Milorganite, Sustane, Nature Safe, Corn Gluten Meal, Renaissance, and urea. An untreated control was also added for comparison. The research was conducted at the Iowa State University turfgrass research area north of Ames, Iowa on Nassau Kentucky bluegrass turf.
