Fact Sheet:

*When harvested for hay or silage, apply 40 pounds of nitrogen (N) per acre at planting, 60 pounds nitrogen per acre after stand establishment, and 60 pounds nitrogen per acre after each harvest except the last. If more than one cutting is anticipated, increase the phosphate (P2O5) and potash (K2O) rates by 25%.

*When used for grazing, apply 40 to 60 pounds of nitrogen per acre for establishment and 50 to 60 pounds of nitrogen per acre each month during the grazing season (June, July, and August).
