A calcareous soil (Haploxeroll calcic) was amended in two different fo
rms according with the standard nutritional requirements of tomato pla
nt. The treatments applied were: i) an organic fertilization applying
sewage sludge (SS), ii) an inorganic fertilization (IN) using mineral
fertilizers (NPK), and iii) a treatment called W where no fertilizer w
as applied. For each treatment, cadmium (Cd) pollution was added to th
e soil establishing different concentrations (0, 3, 30 and 100 mg kg(-
1) d.w.). The availability of macronutrients and micronutrients were a
nalyzed in the soil. Phosphorus (P), iron (Fe), and copper (Cu) were t
he nutrients more affected by Cd. In general, sewage sludge favored th
e availability of nutrients in the same degree of the inorganic fertil
ization.
