Abstract
Laboratory studies were conducted to evaluate some of the factors which influence the microbial degradation of anaerobically digested sewage sludge in soils and the population of microorganisms involved in these processes. Anaerobically digested sewage sludge was rather resistant to decomposition with a maximum of about 20% of the sludge carbon evolved as CO2 in six months. The rate of decomposition at the high loading rates of 90 and 224 metric tons/ha of dry solids was found to be independent of differences in soil chemical properties. Differences in soil texture influenced sludge decomposition indirectly by influencing soil aeration under saturated moisture conditions. A relationship was shown between the percent sludge carbon evolved as CO2 and monthly degree days which will provide a method for predicting the amount of sludge decomposition in a given climatic area based on available temperature data. Accumulation of soluble soil nitrogen and soluble salts in sludge amended soils could limit the rate of application sewage sludge to soils.
