SUMMARY OF RESEARCH PROJECTS
Creeping bentgrass (Agrostis stolonifera L.) has long been a desired cool-season
turfgrass species for use in golf course settings. From greens to tees and fairways, it has
withstood the test of time, becoming the most sought after turf by avid golfers and
greenskeepers alike. After an in-depth look at creeping bentgrass management
recommendations in the Midwest, two main areas are identified as lacking in supporting
research: late-fall nitrogen fertility on putting greens and a cost-effective approach for
fairway establishment in annual bluegrass (Poa annua L.) infested turf.
Late-fall nitrogen fertility has been regarded as an integral component in coolseason
turfgrass nutrition programs for almost four decades. The benefits of this
application from a turfgrass quality standpoint are fairly clear, though recent
environmental concerns and rising nitrogen fertilizer costs have pressured turfgrass
researchers to re-evaluate the benefit and efficiency of these applications. The late-fall
nitrogen research herein focuses on creeping bentgrass in Upper Midwest putting green
situations, with an attempt to quantify benefits and determine nitrogen uptake efficiency
from various application strategies.
Annual bluegrass is a weedy species, which has long been problematic on golf
courses throughout the world. More time and money is devoted to controlling this
species than any other weed, and most attempts have achieved marginal success at best.
Greenskeepers are constantly looking for a cost-effective approach to establish creeping
bentgrass in annual bluegrass infested turf. This research looks at a quick and effective
way to increase creeping bentgrass populations on annual bluegrass fairways.
