Abstract
Not available – first paragraph follows:
Annual ryegrass produces superior yields of hay or pasturage with excellent palatability, a protein content above 20 percent, and other desirable qualities. The new fertilizer technology provides a highly favorable economic return. However, the nitrogen fertilization rates required for highest yields may cause plant nitrate-nitrogen concentrations that are toxic to livestock.
