Summary

Story summary

Virginia Tech research and surveys of golf course superintendents show a shift in nitrogen management for turf, with some endorsing late-fall fertilization to boost turf vigor.
Late-fall nitrogen applications can increase root mass, particularly in Iowa and Virginia, when timing optimizes nutrient uptake.
Historically, experts advised against late-fall applications in the mid-1900s to prevent winter damage.
Superintendents should tailor fall timing to their root-development goals, balancing nutrient efficiency with cost-effectiveness.
