ABSTRACT: In order to preserve the
environment, various treatment processes of wastewater discharges are used.
Anaerobic digestion is part and allows among other things the production of
sludge. The use of sewage sludge in semi arid, characterized by a binding
climate, anthropozoogenic pressure and erosion, more increasingly
important, is a solution for the restoration of degraded forest lands. In this
study, the effect of an intake of composts from urban sewage sludge on soil
quality has been studied in-situ soils degraded in semi arid area. The research followed in this work
methodology is the first to evaluate the effectiveness of contribution of
compost over time on the restoration of the physico-chemical quality of forest
soils, then to evaluate the effectiveness of compost quality depending on the state
of disturbance of the ecosystem to restore the chemical quality of these soils.
Our results show a significant effect of sewage sludge on soil’s physical and
chemical characters that have been processed. This effect was delivered by the
holding capacity increase, ammonium ions, inorganic phosphorus, total nitrogen,
the carbon and the organic matter in these soils. This research is to show that
sewage sludge are rich in easily mineralizable organic matter and are supposed
to be the most suitable for the restoration of soil most impacted by the antropozoogene action. These contributions would
quickly revitalize these soils by labile resource inputs.
