The elimination of sewage sludge is one of the current environmental problems; their valorisation appears as a matter of organization and optimization of the techniques of their management or elimination can play the role of organic fertilizer because of their richness of organic matter and mineral compounds.

This study examines the use of sludge compost elaborated as a fertilizer and compares it with compost without sludge, Manure (traditional input) and bare soil (no input). We studied the impact of these fertilizers on the soil (before and after cultivation), on the parameters of vegetative growth (morphological) and on the parameters of production. The application test was carried out on two crops: radishes and potatoes.

The obtained results showed a significant increase in vegetative growth and production levels compared to bare soil (without input) and manure. For the physicochemical characterizations studied of the soil before and after the planting of the culture tested, the results show that the compost has an effect on soil.
