The objective of the 2005 nitrogen (N) source study was 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 added for comparison.
