Abstract:
:Ammonia volatilisation from field applied slurries causes environmental hazards and loss of fertilizer value. Acidification of slurry, usually with inorganic or organic acids has previously been used to reduce NH3 emissions. In this study, we present an alternative technique for the acidification of slurry, namely the use of fermentation by endogenous microbes to form organic acids from readily degradable organic compounds. In laboratory experiments, the addition of different sugars (sucrose in dosages of 0.003, 0.01, 0.03, 0.1 and 0.3 mol l(-1), glucose in dosages of 0.05 and 0.1 mol l(-1)) and organic residues (sugar beet residues in dosages of 33 and 330 g fresh weight l(-1), biowaste at 50 g fresh weight l(-1)) to cattle slurry resulted in a considerable decrease in pH, with a minimum pH of 4.7. A subsequent pH increase indicated that the organic acids were probably further degraded with a resultant loss of acidity in the slurry. In a field study, the NH3 emissions from untreated and acidified (pH = 6) slurries were compared after field application (20 m3 ha(-1)). During the first 20 hours, the acidified slurry showed NH3 emissions of less than 5% of the applied ammonia compared to a 26% loss from the untreated slurry. The total emissions of NH4+-N were 32% for acidified and 54% for untreated slurry. Easily degradable organic amendments therefore have the potential to effectively reduce NH3 emissions from slurries and may be an alternative for the use of acids.
