Abstract/Contents:Nitrogen is the major nutrient required by grasses in largest quantities and provides the most dramatic effects on turf qualities. The amount of N needed is dependent upon the turfgrass species, soil texture, N sources, rainfall or irrigation, and the desired intensity of culture. There has been a tendency in recent years to overfertilize lawn turf. Yearly N requirements for cool season lawns ranges from 2 to 5 lbs of N per 1000 sq. ft. Sources of N fertilizers differ in their release pattern and differ in their rate of providing nutrition to the turf. Generally, those N fertilizers containing large percentages of water insoluble N (WIN), such as ureaformaldehyde, methylene urea and IBDU, release their N slowly to the plant. The N release pattern, or dissolution rate, of sulfur-coated ureas, is dependent upon the type and thickness of the coating. A late fall N application is advocated in order to increase carbohydrates and stimulate rooting. Timing such as this is important since root development occurs in late winter, early spring. Early spring N fertilization is to be avoided when late fall applications are applied.
