Effects of Antibiotics on the DAMO Process and Microbes in Cattle Manure

Environmental Science & Technology
Denitrifying anaerobic methane oxidation (DAMO) can mitigate methane emissions; however, this process has not been studied in cattle manure, an important source of methane emissions in animal agriculture. The objective of this study was to investigate the occurrence of DAMO microbes in cattle manure and examine the impacts of veterinary antibiotics on ...

Influence of liquid cattle manure on reduction processes in soil

Biology and Fertility of Soils, 1993
Reduction processes in cultivated soil during the decomposition of liquid cattle manure were studied in laboratory experiments. Anoxic slurries of soil and manure in different proportions or alone were followed over 5 weeks. Upon NO inf3 sup- depletion, ferrous Fe appeared in solution in soil-manure ...
