Nutrients in a calcareous soil affected by Cadmium

Abstract A calcareous soil (Haploxeroll calcic) was amended in two different forms according with the standard nutritional requirements of tomato plant. 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 was applied. For each treatment, cadmium (Cd) pollution was added to the soil establishing different concentrations (0, 3, 30 and 100 mg kg‐1 d.w.). The availability of macronutrients and micronutrients were analyzed in the soil. Phosphorus (P), iron (Fe), and copper (Cu) were the nutrients more affected by Cd. In general, sewage sludge favored the availability of nutrients in the same degree of the inorganic fertilization.
