Abstract. Nitrous oxide (N2O) is an important greenhouse gas. N2O emissions from soils vary with fertilization and cropping practices. The response of N2O emission to fertilization of agricultural soils plays an important role in global N2O emission. The objective of this study was to assess the seasonal pattern of N2O fluxes and the annual N2O emissions from a rain-fed winter wheat (Triticum aestivum L.) field in the Loess Plateau of China. A static flux chamber method was used to measure soil N2O fluxes from 2006 to 2008. The study included 5 treatments with 3 replications in a randomized co

Abstract:

Seven different methods of source apportionment were applied in an analysis of the nutrient emissions from point and diffuse sources of 14 river basins in Northeastern Germany. The aim was to compare the results relating to the uncertainties of the methods and to test whether the difference between the emissions and load is caused by systematical errors or by retention and loss processes in the river systems. Beside the simplest method, where the diffuse emission is the difference between the observed transport and the point source inventory, other immission methods including a nutrient retent

Abstract:

Nutrient emissions by point and diffuse sources were estimated for 388 sub-catchments of the Danube river basin for the period 1998–2000 by means of the Model MONERIS. For nitrogen total emissions of 684 kt/a N were estimated for the Danube basin. 80% of these emissions were caused by diffuse sources (mainly groundwater, urban areas and tile drainage). For phosphorus the emission was 57 kt/a P, with a contribution of diffuse sources to this sum of 58%. The comparison of calculated and observed loads shows that the mean deviation for the investigated sub-catchments of the Danube river basin is

The cycle of key nutrient elements nitrogen (N) and phosphorus (P) has been massively altered by anthropogenic activities. Little is known about the impacts on greenhouse gas (GHG) emission of the large nutrient additions occurring in the alpine grasslands of the Tibetan Plateau.

Compared to the control, CO2 flux significantly increased by 14.6% and 27.4% following P and NP addition, respe

Abstract. Nitrogen (N) deposition is generally considered to increase soil nitrous oxide (N2O) emission in N-rich forests. In many tropical forests, however, elevated N deposition has caused soil N enrichment and further phosphorus (P) deficiency, and the interaction of N and P to control soil N2O emission remains poorly understood, particularly in forests with different soil N status. In this study, we examined the effects of N and P additions on soil N2O emission in an N-rich old-growth forest and two N-limited younger forests (a mixed and a pine forest) in southern China to test the followi

Abstract. Leguminous tree plantations at phosphorus (P) limited sites may result in higher rates of nitrous oxide (N2O) emissions, however, the effects of nitrogen (N) and P applications on soil N2O emissions from plantations with N-fixing vs. non-N-fixing tree species has rarely been studied in the field. We conducted an experimental manipulation of N and P additions in two tropical plantations with Acacia auriculiformis (AA) and Eucalyptus urophylla (EU) tree species in South China. The objective was to determine the effects of N- or P-addition alone, as well as NP application together on so

Abstract:

Environmental pollution is defined as the disruption of normal ecological balance with emmision of various substances and energy residues as a result of human activities. Animal production is one of the major human activity that enables this emission to increase significantly. Although ruminants play an important role in the effects of animal production on environmental pollutant emissions, the effects of poultry production and broiler production are also worth considering. As in all livestock types, the main factor that has a direct impact on environmental pollutant emissions is feeding for t

Abstract:

Nitrogen laser induced photoluminescence (PL) emissions from (ZnS: ZnO):Cu powder phosphors have been carried out under varying conditions of sample preparation. The conditions for optimum efficiency of PL emission in (ZnS: ZnO):Cu phosphors and their spectral characteristics have been investigated. The emission peak in the PL spectra was found to shift towards longer wavelengths side as the concentrations of ZnO in (ZnS: ZnO) mixture was varied from 0% to 100%. The mechanism of PL emission in the above phosphor is explained on the basis of classical “Schon-Klassen” model.

Designing efficient agri-environmental policies for agricultural nutrient load reductions calls for information on the costs of emission reduction measures. This study develops an empirical framework for estimating abatement costs for nutrient loading from agricultural land. Nitrogen abatement costs and the phosphorus load reductions associated with nitrogen abatement are derived for crop farming in south-western Finland. The model is used to evaluate the effect of the Common Agricultural Policy reform currently underway on nutrient abatement costs. Results indicate that an efficiently designe

The contamination of waters with nutrients, especially nitrogen and phosphorus originating from various diffuse and point sources, has become a worldwide issue in recent decades. Due to the complexity of the processes involved, watershed models are gaining an increasing role in their analysis. The goal set by the EU Water Framework Directive (to reach “good status” of all water bodies) requires spatially detailed information on the fate of contaminants. In this study, the watershed nutrient model MONERIS was applied to the Hungarian part of the Danube River Basin. The spatial resolution was 10

In this study, a two-step fed sequencing batch reactor (SBR) was employed to treat dairy manure wastewater to remove nutrients, including nitrogen, phosphorus, 5-day biochemical oxygen demand (BOD5), and chemical oxygen demand (COD), and to examine the associated nitrous oxide (N2O) emission by the SBR treatment. The SBR was operated on an 8 h cycle with preset time periods for different phases, including anoxic/anaerobic/aerobic phases. The results showed that the SBR system could effectively reduce the nutrients in the wastewater, with removal efficiencies reaching 86.6%, 95.6%, 98

The results showed that the soil had a low pH (3.89 - 5.12), a high total phosphorus (0.1 % P2O5) and lower potential redox (from -186 to -145 mV). The organic matter (54.6 %) and total nitrogen (1.15 %) were high in thick peat layers. The organic matter (2.15 - 3.
