OBJECTIVE To compare the incidence, nature, severity and cause of match injuries sustained on grass and new generation artificial turf by male and female footballers. METHODS The National Collegiate Athletic Association Injury Surveillance System was used for a two-season (August to December) prospective study of American college and university football teams (2005 season: men 52 teams, women...

Turf is not a material frequently associated with construction. However, as cheap, easily available, and versatile it was used in antiquity (and has been various contexts since) to form unit-based mass walls, embankments, ramparts. Some of the best-preserved evidence for historical turf use comes from Roman period, when mainstay military construction, being widely forts (e.g. along Rhine Britai...

BACKGROUND Turf toe is the general term for a sprain of the first metatarsophalangeal (MTP) joint complex. Previously attributed to shoe design and artificial turf, the incidence of turf toe injury has been thought to decline with the advent of newer turf designs. However, the current incidence and epidemiology remain unknown as the majority of the literature consists of small series and addres...

Bentgrass species are widely utilized on golf course fairways in cool climatic regions. Among the 200 species of bentgrass that exist, creeping (A. stolonifera), colonial (A. capillaris), and velvet (A. canina) bentgrasses have received the greatest breeding improvements and are the most widely utilized Agrostis species for turf. Each bentgrass species retains particular qualities relating to d...

Experiments were conducted to quantify the effects of the sting nematode (Belonolaimus longicaudatus) on root reductions and quantity of nitrate (NO(3) (-)) leached from 'Tifdwarf' bermudagrass in lysimeters. Forty lysimeters were planted with 'Tifdwarf' bermudagrass, of which 20 were inoculated with B. longicaudatus and 20 were noninoculated. Root length was compared between treatments at six,...

introduction: water is the main carrier of herbicides (hc) that its quality plays an important role in herbicide performance hard water has a high concentration of ca++ and mg++ and reviews have shown that calcium, manganese and zinc are the main factors reducing the effectiveness of weak acid herbicides. weak acid herbicides such as glyphosate, paraquat, clethodim and 2, 4 d are compounds that...

The market for turf-type perennial ryegrass (Lolium perenne) continues to grow with over $70 million in seed sales in 1994. Breeders in private companies are capitalizing on this increasing ryegrass popularity by continuing to make improvements in turf quality traits such as color, density, texture, mowability and disease resistance. However, all current improved turf-type cultivars do not have...

The health of several East Antarctic moss-beds is declining as liquid water availability is reduced due to recent environmental changes. Consequently, a noninvasive and spatially explicit method is needed to assess the vigour of mosses spread throughout rocky Antarctic landscapes. Here, we explore the possibility of using near-distance imaging spectroscopy for spatial assessment of moss-bed hea...

Fall season fertilization is a widely recommended practice for turfgrass. Fertilizer applied in the fall, however, may be subject to substantial leaching losses. A field study was conducted in Connecticut to determine the timing effects of fall fertilization on nitrate N (NO3-N) leaching, turf color, shoot density, and root mass of a 90% Kentucky bluegrass (Poa pratensis L.), 10% creeping red f...
