Isoprene emission from wetland sedges
High latitude wetlands play an important role for the surface-atmosphere exchange of carbon dioxide (CO2) and methane (CH4), but fluxes of biogenic volatile organic compounds (BVOC) in these ecosystems have to date not been extensively studied. This is despite BVOC representing a measurable proportion of the total gaseous C fluxes at northern locations and in the face of the high temperature se...
متن کاملEffects of Citric Acid on Growth Performance and Nutrient Retention of Broiler Chicken Fed Diets Having Two Levels of Non-Phytate Phosphorus and Rice Bran
Citric acid has been reported to increase utilization efficiency of dietary phytate-bound phosphorus and protein. Objective of this study was to determine the effects of citric acid on growth performance and nutrient retention of broiler chickens fed diets having two levels of non-phytate phosphorus and rice bran. Giving a completely randomize design in 2 × 2 × 2 factorial arrangement, 144 broi...
متن کاملEffect of influent nutrient ratios and hydraulic retention time (HRT) on simultaneous phosphorus and nitrogen removal in two-sludge sequencing batch reactor
A laboratory-scale anaerobic-anoxic/nitrification sequencing batch reactor (A2N-SBR) fed with domestic wastewater was operated to examine the effect of varying ratios of influent COD/P, COD/TN and TN/P on the nutrient removal. With the increased COD/P, the phosphorus removals exhibited an upward trend. The influent TN/P ratios had a positive linear correlation with the phosphorus removal effici...
متن کاملWet Feeding Mitigates the Adverse Effectsof High Dietary Rice Bran Levels on Growth Performance and Nitrogen Retention of Broiler Chickens
The objective of this study was to evaluate whether the adverse effects of high dietary rice bran (RB) inclusion levels on the feed intake, performance, bone status and nitrogen (N) retention of broilers could be mitigated by wet feeding. Giving a completely randomized design experiment in 2 × 2 factorial arrangement, seventy two broiler chickens, managed in 24 floor pens received one of the tw...
متن کاملA test of four plant species to reduce total nitrogen and total phosphorus from soil leachate in subsurface wetland microcosms.
Four wetland plant species (Scirpus validus, Carex lacustris, Phalaris arundinacea, and Typha latifolia) were grown in monoculture and as a four-species mixture to compare effectiveness of nutrient removal in controlled 18.93-l outdoor subsurface treatment wetland microcosms. A nutrient treatment that mimicked single-resident domestic effluent consisted of two levels of nitrogen (N) and phospho...
