The main objective of this work was to determine the total mineral nitrogen in three soils with three organic residues pig slurry, urban waste and sewage sludge, after 42 weeks in laboratory incubation. When the residue was pig slurry the results showed that the cumulative N mineralized (NH4+NO3)-N lor soil A was 600 mg (NH4+NO3) -N/kg; 313 and 408 mg (NH4+NO3)-N /kg for soil B and sand respectively. The cumulative N mineralized (NH4+NO3)-N /kg for sewage sludge was 253 mg (NH4+NO3)-N /kg in soil A, 366 mg (NH4+NO3) -N /kg in soil B and 258 mg(NH4+NO3) -N /kg in sand. Finally, in urban waste, nitrogen was immobilizated in the three studied soils.
