Schätzrahmen zur Beurteilung von Ammoniakverlusten nach Ausbringung von Rinderflüssigmist

Abstract: In den Jahren 1988 und 1989 wurden auf verschiedenen Standorten und bei unterschiedlichen Umweltbedingungen mit Hilfe der Integrated Horizontal Flux Methode Messungen der NH3‐Verluste nach Ausbringung von Rinderflüssigmist durchgeführt. Ziel dieser Untersuchungen war es, die NH3‐Verluste zu quantifizieren sowie die dafür verantwortlichen Einflußfaktoren zu erfassen und zu bewerten. Je nach Umweltbedingungen und Infiltration betrugen die NH3‐Verluste der in dieser Arbeit dargestellten Versuche zwischen 12 und 6… Show more

“…There are various nutrient solution studies indicating that root growth is severely inhibited by high ammonium supply whereas with a low N supply ammonium-fed plants exhibited at least equal root growth to that of nitrate-fed plants (for review see Bloom et al, 1993). In field studies maximum root-length densities were achieved with lower ammonium than nitrate concentrations in the soil ( Bloom et al, 1993) and, at a given N supply, mean root-length densities in the top soil were higher with ammonium than with nitrate fertilization (Horlacher, 1991). This may improve the uptake of nutrients with low mobility in the soil and has, therefore, a synergistic effect with the nutrient mobilization resulting from acidification of the rhizosphere.…”

“…All treatments showed maximum volatilization rate during the measurement period immediately following application, with a subsequent decrease of the rate to low NH, release during the night (1 1-19 hours after application). High NH, volatilization rates soon after slurry application are quite common (Amberger, 1990, Horlacher & Marschner, 1990, Mannheim et al, 1995. The highest volatilization rate measured during this experiment (untreated, broadcast slurry in dry weather) reached 210 pg NH,-N m-' s-I, corresponding to nearly 8 kg NH,-N ha-' h-' or a loss of 48% of TAN from applied slurry during the first 3.5 hours.…”

“…A mmonia (NH 3 ) volatilization after spreading of liquid organic fertilizers is an important vector of N loss from agricultural systems. Up to 90% of NH + 4 –N applied with slurry can be lost through NH 3 emissions (Horlacher and Marschner, 1990), substantially reducing the amount of plant‐available N. In the early 20th century research was performed to improve the fertilizer effect of liquid waste. In addition to the use of slurry additives, application technique was also identified as a possible means to reduce NH 3 losses (Blanck, 1918; Gerlach, 1918; Heck, 1931).…”
