Treatments included: 1) Kentucky bluegrass with a berm, 2) Kentucky bluegrass without a berm, 3) native mixture with a berm, and 4) native mixture without a berm, and they were planted in October 2005. Each plot had a separate rooftop, lysimeter, and runoff weir. Runoff and leachate volumes and samples were collected as appropriate. All samples were analyzed for NO3, NH4, total P, and dissolved P. Runoff samples were also analyzed for total suspended solids. After one year of data collection, both bermed treatments significantly reduced the amount of runoff and increased the amount of leachate when compared to both unbermed treatments. The unbermed native mixture treatments produced over two times more runoff than did the unbermed Kentucky bluegrass treatments. These results indicate that the presence of a berm appears to be the major determining factor behind rain garden effectiveness, regardless of vegetation ...

Overseeding with bentgrass is common practice on most northern championship The second hole at Merion Golf Course - site of the 1981 Open Championship. courses. Bentgrass Fairways WhyNot? by PATRICK Agronomist, M. O'BRIEN Mid-Atlantic Region, USGA Green Section Golf Club, Springfield, N.J., Winged Foot Golf Club, Mamaroneck, N.Y., and Merion Golf Club, Ardmore, Pa., have chosen bentgrass for their fairways. Our technology and ability to grow bentgrass is certainly not lacking, so what are the problems? Over-Irrigation Perhaps no grass has been so mismanaged by irrigation practices as bentgrass. It ranks favorably but slightly behind Kentucky bluegrass and the fine fescues in drought tolerance. Bentgrasses are widely used in Scotland, where there is no artificial irrigation. The bentgrasses have also been found growing in desert areas. Yet somehow bentgrasses have the reputation of needing much more water than other permanent turfgrasses. Before irrigating, it is good practice to use a soil prob ...

LOLIUM - FOLIUM Perennial Ryegrasses are Getting Better! by STANLEYJ.ZONTEK Director, North-Central Region, USGA Green Section 0NG THE 1,500 or so species of grasses growing in the United States, only about a dozen are suitable for turfgrass purposes. Even on that limited scale, ryegrasses have never received a very high rating. Their early use was limited mostly to southern golf courses for overseeding bermudagrass for winter color. They were accepted in the more northern areas of the country as a short-lived nurse or companion grass for Kentucky bluegrass and fescue blends. The annual or Italian ryegrasses (Lolium multiflorum Lam.) and early varieties of perennial ryes (Lolium perene L.) were either true annuals or, at most, shortlived perennials. They had wide and coarse leaf blades, were susceptible to a wide range of diseases, were stemmy and oftentimes difficult to cut and maintain. They had a very distinctive and not necessarily pleasing color and growth could stand alone as distinct varieties. They d ...

In addition to the turf plots, several nursery rows are maintained for identification purposes and to supply planting material. On these plots 18 varieties and strains of grass are being tested, consisting of Kentucky bluegrass , redtop, buffalo grass, and 15 strains of bent. The Kentucky bluegrass and 1 series of 8 plots, making an area 10 feet wide and 80 feet long comprising 8 strains of bent, are cut at lawn or fairway height. This is done to determine the adaptability of the bents for lawns in this locality. The Kentucky bluegrass must all be cut high, because it is quickly destroyed by close mowing in this section. The remaining 63 plots are kept cut close with a putting green mower. Fortytwo plots are devoted to tests of fertilizers. These consist of duplicate series of 7 plots each of bluegrass, German mixed bent, and \Vashington creeping bent. Each fertilizer treatment is applie ...

	SeedingintheWinter Iowa State, B 90657 Excerpt: ... Extension Notes Personal Column By Gary Hall, ISU County Extension Education Director, Cerro Gordo County, Iowa Seeding in the Winter?!?!? With all the flooding and damage done to turfgrass you may be thinking about seeding that bare spot next spring. Actually the best time to seed cool-season grasses such as tall fescue and Kentucky bluegrass is September because the turf has more time to mature before spring crabgrass germination and the heat stress of summer. However, dormant seeding of turfgrass is sometimes used. Dormant overseeding is done during the winter (December February) when it is much too cold for seed germination. As with any seeding program, good seed-soil contact is vital. A number of methods can be used to get that critical contact between the seed and the soil. One method is to seed when there has been a light snowfall of up to an inch. This is shallow enough that bare spots can still be seen. Spread seed by hand on areas that need thickening up. As the snow melts, it brings the seed in ...

	730701 Michigan State University, LIB 1973 Excerpt: ... putting green turf. annual bluegrass is a weed. Simply defined, a weed is a plant that is out of place. On putting greens in the South a heavy Poa population during the transition months tends to shade the desired bermudagrass species and slows its emergence from its winter dormancy. I n some cases this results in a painfully late and slow transition resulting in poor playing conditions. I n the North it is considered a weed because of its competition with bentgrasses and Kentucky bluegrass es for the dominant grass species on the main playing areas of the course (greens, collars, tees and fairways). When Poa annua is only a small percentage of the total grass population on the course there are few problems. However when the population becomes a majority, the possibility exists that the Poa could be thinned out or entirely lost during the summer stress period. This poor summer performance is the principal reason why Poa annua is considered a weed under most coolseason turfgrass cultures. the cool humid region ...

As for our cultivated turf grasses, notwithstandlllg the many years they h~ve been grown and studied it is l'egrettable but true that their soil relations so far as acidity is concerned have in no case been critically determined. It appears to be true, however, that at least the bents and fescues-that is, the ones that we use in making putting greens-are so constituted as to thrive vigorously on acid soils. \Vhen it is said that the soil relations of our turf grasses, so far as acidity is concerned, have not been scientifically determined, it is with full appreciation of the fact that there is almost au overwhelming notion that Kentucky bluegrass is a species that requires a so-called sweet soil for iis best growth. Furthermore, it is very generally thought that it requires a soil well supplied wi ...
	760901 Michigan State University, LIB 1976 Excerpt: ... ere is no better way to perpetuate Poa annua than by annual aeration in early spring and late fall. If no Poa annua suppressant is used, you might best save your money, time and energy. Poa annua is going to win. Choosing the right seed or stolons is important. Choices for the northern climate for fairways include the bentgrasses, bluegrasses, fescues and ryegrasses. Simply sowing the seed doesn't assure success because there are pitfalls in using some of these grasses on established turf. For example, any attempt to introduce a Kentucky bluegrass seed into a predominately Poa annua turf is virtually impossible. The bluegrasses take up to 21 days to germinate and this gives Poa annua too much of a head start in establishment. On the other hand, seeding Kentucky bluegrass es, the new perennial ryegrasses and fescues into predominately Kentucky bluegrass fairways is a good practice. This can be successfully accomplished! Seeding bentgrasses into an existing Kentucky bluegrass stand will provide results, since b ...

	mowing1 Texas A&M, AGRO 302 Excerpt: ... cape maintenance, mowing and trimming around trees and shrubs and other structures significantly increases the cost of mowing. 5 In Amarillo, Texas a Kentucky bluegrass lawn can be mowed every other week at a 4 inch height during summer months. The peak periods of growth for Kentucky Bluegrass are spring and fall. 6 Sports fields present a special problem relative to mowing practices since the use of the facility dictates availability of the site and the mowing heights required. At Texas A&M Universitys Kyle Field, at fast uniform surface is desired. The field is mowed daily at a height of between and inches to produce the speed desired. 7 The striping effect apparent on sports fields is produced by mowing the turf in different directions. In this example, the turf between the goal line and the 5 yard line is mowed away from the viewer and between the 5 and 10 yard lines toward the viewer. The light reflection produces the color response. 8 The frequent use of baseball facilities such at ...
