Sunflower (Helianthus annuus) growers in North Dakota and South Dakota harvested 593,522 ha in 2012, valued at $US600 million. Blackbirds, numbering about 75 million, annually damage 2 to 3% of the crop. Damage tends to be clumped around cattail (Typha spp.) dominated wetlands with standing water. In an attempt to reduce sunflower damage, three general population management strategies have been...

Experiments focused on evaluating the ability of three aquatic plant species (sweet flag, common reed, and broadleaf cattail) to decontaminate industrial wastewater effluents from a nitroglycerin and nitroglycol production factory were carried out in the framework of this study. Toxicity of a nitrate-rich wastewater toward the studied plant species was determined by measurement of plant biomass...

Evapotranspiration rate, ETaand vegetation composition strongly influence the water budget of wetland impacting available and resource management. One goals this study was to estimate areal ETa Kis-Balaton wetland, KBW (natural ecosystem) between 1997 2012. This time period free any human intervention. accounted for different classes through multiplication reference evapotranspiration, ET0 by p...

The potential of cattail (Typha latifolia) and water hyacinth (Eichhornia crassipes) biomass to remove Pb Cd ions from metal solutions was determined. removal efficiency decreased with the increase in initial concentration aqueous solution but increased doses. biosorption unaffected by pH 5.0 6.5. Metal contact time then reached equilibrium about 45 min. Higher qmax (the Langmuir model) KF Freu...

background: constructed wetlands (cw s ) are mimic filtration process in natural wetlands that effectively remove variety pollutants from wastewater. the main objective was the feasibility evaluation for using of subsurface flow constructed wetland in nitrogen and phosphorus removal from synthetic based on domestic wastewater in lab scale. methods: in this study, a synthetic wetland subsurface ...
