The objectives of this research were to evaluate nitrate N (NO³-N) leaching and turf response to nitrogen rate (NR) and irrigation regime (IR) in 'Floratam' St. Augustinegrass ( [Walt.] Kuntze.) and 'Empire' zoysiagrass ( Steud). The research was conducted in Citra, FL, from 2005 through 2007. Nitrogen (N) was applied at annual rates of 32, 64, 128, and 196 kg ha⁻¹ in 2005, and at 49, 196, 343,...

Traction between a football shoe and the playing surface influences players’ ability to perform football-specific movements. Too little traction means player might slip. much is thought increase risk of injury due foot fixation on turf. Rotational linked increased in football. Elite increasingly played hybrid reinforced natural grass surfaces. Our aim assess magnitude rotational one new turf sy...

Urban grasslands not only provide a recreational venue for urban residents, but also sequester organic carbon in vegetation and soils through photosynthesis, and release carbon dioxide through respiration, which largely contribute to carbon storage and fluxes at regional and global scales. We investigated organic carbon and nitrogen pools in subtropical turfs and found that dissolved organic ca...

The objective of this study was to determine the protective effect of glutamate (Glu) in Cu-induced oxidative injury in fish intestine in vivo and enterocytes in vitro. The results indicated that exposure to 6 mg/l Cu for 72 h induced the production of reactive oxygen species, thereby increasing protein oxidation and lipid peroxidation in enterocytes of grass carp in vitro. Cells exposed to Cu ...

Research is required on sod to explore the differences in management and postharvest practices help inform producers reduce information inefficiencies that affect supply demand of cool-season turfgrass sod. Replicated field experiments were conducted Indiana Minnesota quantify effect species (strong creeping red fescue [Festuca rubra L. ssp. Gaudin], Chewings [F. commutata tall arundinacea Schr...

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...

Title of Document: TOWARDS AN AUTONOMOUS ALGAL TURF SCRUBBER: DEVELOPMENT OF AN ECOLOGICALLY-ENGINEERED TECHNOECOSYSTEM David M. Blersch, Ph.D., 2010 Directed By: Associate Professor Patrick C. Kangas, Department of Environmental Science and Technology The development of an autonomous and internally-controlled technoecological hybrid is explored. The technoecosystem is based on an algal turf sc...

Rapid changes in practices used to produce perennial grass seed crops in the U.S. Pacific Northwest region and shortened lengths of time that perennial grass seed fields remain in production have increased the need for additional rotation crops that are adapted to the poorly drained soils found in western Oregon. This research was conducted at three sites to determine ways to manage meadowfoam ...

Nitrogen is essential for the proper growth and development of all fi eld crops including corn. Without suffi cient N, both corn yields and silage quality can be impacted. Too much N can be a waste of money and leads to environmental losses. Producers and consultants asked if additional N was needed for corn following legume and/or grass sods in the rotation (fi rst year corn) and if the answer...
