International audienceTwo levels of sewage sludge (10 and 100 tons DM ha-1) were mixed in the 0-20 cm layer of an oxisol in Guadeloupe (French West Indies) (table I). A field experiemnt was conducted with microplots (20 m2) during a 500-d test period: control without sewage sludge (T), (10 T) and (100 T). After soil sampling, sewage sludge clods over 5 mm diameter were handsorted from soil samples. The evolution of various soil phosphorus forms total (Pt), organic (Po), mineral (Pm) and extracted with bicarbonate-fluorure (P NaHCO3-F) was studied. In the 10 t treatment sludge clods disappeared within 110 d, and the total soil phosphorus content significantly increased 3 months after burying up to 600-650 μg●g-1. In the 100 t treatment, sewa...
