In order to valorize the sludge from refining sugar as compost, we are interested to studying the effect of the sludge on the chemical quality of an agricultural soil in the area of Casablanca. The device split plot with three repetitions was used in two crops (wheat and Lucerne). The valorization of sludge is conducted by testing three progressive doses of 50g, 100g and 200g of sludge for both cultures. Chemical indicators assessed soil quality namely: organic matter (OM), pH, calcium carbonate and salinity. Analyzes of soil samples taken at different stages of the life cycle have shown that the contribution of sludge contributes to the enrichment of organic matter and calcium carbonate and an increase in the salinity. This enrichment is higher in cultivated soils compared to uncultivated soils. In contrast, the pH values do not seem to be affected by the addition of sludge, but they record different effects depending on the two cultures.
