Avaliou-se o efeito da dose de N-ureia (40, 80 e 120 kg ha -1 de N) e da distância (0,27 e 35 cm) entre dreno (folhas) e fonte (ureia aplicada ao solo) sobre a absorção foliar de amônia por pastagem de Panicum maximum cv. Tanzânia. Adotou-se um delineamento inteiramente casualizado no esquema de parcelas subdivididas, com quatro repetições. Não houve efeito da distância sobre a absorção foliar de amônia (p>0,05), mas esta diminuiu exponencialmente (p<0,05) com o incremento das doses de N-ureia ou da taxa de volatilização de amônia, variando de 2,5 a 16,4% do N volatilizado.

Air Emissions of Ammonia and Methane from Livestock Operations: Valuation and Policy Options

AgEcon

Shih, Jhih-Shyang; Burtraw, Dallas; Palmer, Karen L.; Siikamaki, Juha.

The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter, arguably the number-one environment-related public health threat facing the nation. We present an integrated process model of the engineering economics of technologies to reduce methane and ammonia emissions at dairy operations in California. Three policy options are explored: greenhouse gas offset credits for methane control, particulate matter offset credits for ammonia control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane gas. Individually, any of these policies appears to be sufficient to...

This study uses a linear programming approach to compare the potential effectiveness of uniform rules (under the Integrated Pollution Prevention and Control Directive) and a landscape-scale based policy for reducing ammonia (NH3) emissions and their related impacts from a case study poultry installation. The model incorporates a variety of potential NH3 abatement techniques. It also incorporates the first application of a spatial model of the diffusion of environmental impacts from NH3 emissions. This models N deposition at a nearby nature reserve. The model finds that the uniform rules proposed under the Integrated Pollution Prevention and Control Directive are likely to be ineffective in certain contexts and that a landscape-scale approach is more...

Little is known about gaseous carbon (C) and nitrogen (N) emissions from traditional terrace agriculture in irrigated high mountain agroecosystems of the subtropics. In an effort towards filling this knowledge gap measurements of carbon dioxide (CO_2), methane (CH_4), ammonia (NH_3) and dinitrous oxide (N_2O) were taken with a mobile photoacoustic infrared multi-gas monitor on manure-filled PE-fibre storage bags and on flood-irrigated untilled and tilled fields in three mountain oases of the northen Omani Al Jabal al Akhdar mountains. During typical 9-11 day irrigation cycles of March, August and September 2006 soil volumetric moisture contents of fields dominated by fodder wheat, barley, oats and pomegranate ranged from 46-23%. While manure incorporation...

Combined effect of external ammonia and molt stage on the blue shrimp Litopenaeus stylirostris physiological response

Mugnier, Chantal; Justou, Carole.

The effect of ambient ammonia and molt stage on the physiological response of the blue shrimp Litopenaeus stylirostris was studied. Shrimps were submitted to 54.6 mg l(-1) ammonia-N (1.76 mg l(-1) NH3-N) for 24 h. Only shrimps in stages C, D-0, D-1 and D-2 were used for the analysis. Haemolymph was assayed for osmoregulatory capacity (OC), magnesium ion (Mg ion), total proteins, oxyhaemocyanin, lactate and glucose. Molt stage had an effect on OC, Mg ion and total proteins in control shrimps, and on OC, Mg ion and lactate in treated animals. Ammonia treatment decreased OC and lactate, and increase Mg ion concentration in haemolymph, for all molt stages. It decreased significantly total proteins and oxyhaemocyanin for stages D-1 and D-2, and increased...

Comparison of brown trout (Salmo trutta) reared in fresh water and sea water to freshwater rainbow trout (Oncorhynchus mykiss) .1. Growth and nitrogen balance

Dosdat, Antoine; Metailler, Robert; Desbruyeres, Elisabeth; Huelvan, Christine.

Brown trout and rainbow trout (average weight 100 g) were reared in fresh water at 12 degrees C under the same conditions before transfer of brown trout to sea water, in order to compare nitrogen utilisation in the two species. Apparent protein digestibility (ADC), nitrogen (ammonia and urea) excretion, protein productive value (PPV) and actual observed nitro en mass balance were determined. Rainbow trout raised in fresh water had a higher growth rate (1.1 vs 0.8%. d(-1)), better food conversion ratio (0.7 vs 1.0), better ADC (91 vs 85%) and PPV (45 vs 35%) and lower ammonia excretion rates than brown trout reared in fresh water. Transferring brown trout to sea water induced lower PPV (30%) and ammonia and urea excretion. Salinity did not modify metabolic...

[[abstract]]Manure management systems are conducive to nutrient and carbon losses, but the magnitude of the loss highly depends on the nutrient element, the manure management system and the environmental conditions. The aim of this paper is to contribute to the understanding of the diffusive nutrient losses. Firstly, we discuss the main mechanisms loss path ways of nutrients from manure management systems to groundwater, surface waters and air, using some data from the European Union (EU-27). Secondly, we discuss possible measure to decrease diffuse pollution and to increase the environmental performance of livestock production and manure management. Finally, we give some policy recommendations. In general, losses from animal manure...

Distribución espacial del amonio en fiordos y canales comprendidos entre Puerto Montt y Laguna San Rafael en período de primavera

OceanDocs

Prado-Fiedler, R..

An oceanographic expedition was carried out between October 18th and November 15th 1995 in the inlets region and fjords located between Puerto Montt (41° 20’S and San Rafael Lagoon (46° 40’ S) in Southern Chile. The main purpose of the present work is to characterise the spatial distribution of ammonium and its concentration range in the studied region during spring onset. Water samples were collected from a total of 101 oceanographic stations of the expedition Cimar-Fiordo 1. The main part of the water body showed concentrations lower than 1 µmol/L. The higher ammonium concentrations were found in the continental fjords, specially in the area situated south of the narrows of Meninea island, where subsurface maximums greater than 2 µmol/L were found. The...

Effect of chronic exposure to ammonia on alterations of proteins and immunoglobulins in sea bass (Dicentrarchus labrax) serum

Lemarie, Gilles; Dosdat, Antoine; Coves, Denis; Dutto, Gilbert; Gasset, Eric; Person, Jeannine.

Chronic effects of ammonia were studied in juvenile seabass, Dicentrarchus labrax (mean weight= 11 g), exposed for 63 days to eight stable ammonia concentrations, ranging from 0.24 to 0.90 mg l(-1) unionised ammonia nitrogen (UIA-N), respectively, from 6.1 to 22.3 mg l(-1) total ammonia nitrogen (TA-N). Temperature (21.8 degreesC), pH (8.0), salinity (37.0 ppt), and oxygen concentration (over 80% saturation at the outlet) were maintained constant. Fish were fed using a self-feeder device, and they were starved during the last 8 days. Mortality of 28.9 and 42.6% occur-red within the first 8 days at the two highest UIA-N concentrations, respectively, 0.90 and 0.88 mg l(-1). From days 0 to 55, a 1.8-fold increase in weight gain was observed under the 0.90-mg...
