These keywords were added by machine and not by the authors. In addition, reliable quantitative data are needed to estimate trace gas fluxes on regional scale. More detailed studies of the influence of vegetation and C dynamics on trace gas emission rates in riparian areas are necessary. In course of the year, relations between available N compounds in the soil and trace gas emissions have been superimposed by environmental factors of the site (water level, vegetation, temperature). In connection with the actual vegetation, eutrophication led to an increase of the two climate-relevant trace gases. High water level led to slightly decreased N 2O-emissions as well as to drastically enhanced CH 4-emissions, and vice versa. All investigated kettle holes have been identified as significant sources of N 2O and, particularly, CH 4. Here you can gently pry the lid upwards.Emission of nitrous oxide and methane in riparian areas with alternating water levels of two strongly eutrophic (polytrophic) kettle holes (“Breites Fenn”, “Krummer Pfuhl”) and one less eutrophic kettle hole (“Klarer Pfuhl”) on agriculturally used sites in Northeast-Germany have been measured and compared. When a battery replacement is needed, please stick with a thin knife or similar into the small slot at the lower end of the red cover. The device even works with aluminum gas cylinders if it is pressed against the cylinder manually. The GASLEVEL® Classic has a magnetic back, so you simply place it up against the gas cylinder and move it downwards until the indicator changes from red to green – when it reaches the area filled with liquid gas. Within seconds the GASLEVEL® Classic measures the level of gas remaining in 5 kg, 11 kg and 33 kg propane gas cylinders. It is the ideal accessory for all people who use gas bottles. The reliable fill level indicator is light weight and has slight dimensions, so it is easy to put away and readily available. Practical, handy, fast – the GASLEVEL® Classic shows the actual fill level of a standard propane cylinder within seconds.
