The abundance of reef builders, non-builders and the calcium carbonate produced by communities established in Calcification Accretion Units (CAUs) were determined in three Abrolhos Bank shallow reefs during the period from 2012 to 2014. In addition, the seawater temperature, the irradiance, and the amount and composition of the sediments were determined. The inner and outer reef arcs were compa...

Plant-parasitic nematodes are important pathogens of intensely-managed turf used on golf courses. Two of these nematodes that are common in the southeastern US are Belonolaimus longicaudatus and Mesocriconema ornata. Currently, there is a lack of effective treatments that can be used to manage these important pests. Turfgrass field trials evaluated DL-methionine as a turfgrass nematicide agains...

In recent years agricultural practices in New England have undergone dramatic changes. Traditional dryland crops such as potatoes and silage corn have been replaced by irrigated “landscape” crops; specifically turf and nursery crops. For example, commercial sod production in Rhode Island has risen from 200 acres in 1972 to over 2,500 acres in 1986, while potato acreage has shown a similm declin...

Pesticides applied to turf grass have been detected in surface waters raising concerns of their effect on water quality and interest in their source, hydrological transport and use of models to predict transport. TurfPQ, a pesticide runoff model for turf grass, predicts pesticide transport but has not been rigorously validated for larger storms. The objective of this study was to determine Turf...

I B entgrasses are grown for golf purposes under conditions more severe and restrictive than for grasses grown under natural field conditions. As a result, prevention and control of disease becomes more difficult, particularly on greens. Bentgrass greens require large applications of nitrogen fertilizer each year. These high levels of nitrogen are needed to maintain the vigor of grass subjected...

Irrigation effects on pesticide mobility have been studied, but few direct comparisons of pesticide mobility or persistence have been conducted on turfgrass versus bare soil. The interaction of irrigation practices and the presence of turfgrass on the mobility and dissipation of mefenoxam [N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-D-alanine methyl ester] and propiconazole (1-[[2-(2,4-dichlorophe...

BACKGROUND Shoe-surface interactions have been implicated in the high number of noncontact knee injuries suffered by athletes at all levels. PURPOSE To examine shoe-surface interactions on newer field designs and compare these with more traditional shoe-surface combinations. The peak torque and rotational stiffness (the rate at which torque is developed under rotation) were determined. STUD...
