abstract:
This paper reviews the characteristics of sewage sludge and its influence on the microbiological and biochemical properties of soils. Among others, changes of the enzymatic activity (protease, urease, dehydrogenases and phosphatases) as the effect of sewage sludge application to soil are discussed. The next part of this paper is concerned with the impact of sewage sludge on ammonification and nitrification as well as population numbers of microorganisms responsible for those processes, and on the respiration activity and total number of soil microorganisms.
