Efficient use of manure N is important economically and because unused N is lost to the environment. Measures that reduce N losses but do not result in greater crop N uptake will increase alternate loss pathways. Manure N efficiency can be evaluated best in steadystate long-term trials in which the recovery of both the new and legacy N is determined. There have been few long term trials on slurry manure in which low-emission applicators have been used and responses of different grasses to manure and fertilizer is not well known. This long-term study compares recovery of N from surface-banded dairy slurry and fertilizer by three perennial grasses: perennial ryegrass (Lolium perenne L.), orchardgrass (Dactylis glomerata L.) and tall fescue (Festuca arundinacea Schreb.).
