Abstract

Background and Objectives: Soil pollution with heavy metals is increasing significantly and created major environmental problems worldwide. CADMIUM and LEAD are among the heavy metals entering into the soil through various means such as the burning of fossil fuels, municipal solid waste, chemical fertilizers, pesticides, sewage sludge, etc. Several studies have shown that the use of phosphate fertilizers resulted in the transfer of heavy metals to agricultural crops. On the other hand, potential of calcareous soils in the stabilization of P have caused the need for using natural modifier along with phosphate fertilizers for increasing their effectiveness.Materials and Methods: In order to compare the native PHOSPHATE ROCK and imported TRIPLE SUPERPHOSPHATE treated with sulfur and THIOBACILLUS in transferring LEAD and CADMIUM into Pistachio seedling, CADMIUM and LEAD contamination in imported TRIPLE SUPERPHOSPHATE and native rock phosphate samples were first analyzed and then, the ability of the two phosphorus fertilizers treated with elemental sulfur and THIOBACILLUS to accumulate LEAD and CADMIUM in pistachio seedlings was evaluated. For this purpose, a pot experiment was conducted as factorial based on completely randomized design with three replications including three levels of phosphate fertilizers (control (P0), 2000 mg PHOSPHATE ROCK per kg soil (PR) and 67 mg TRIPLE SUPERPHOSPHATE per kg soil (TSP)), two levels of elemental sulfur (0 (S0) and 2000 mg sulfur per kg soil (S1)) and two levels inoculums (no inoculation (T0) and THIOBACILLUS inoculation (T1)). CADMIUM and LEAD concentrations in shoots and roots were measured and also analyzed in both phosphate fertilizers.Results: Results showed that the mean value of CADMIUM concentration in imported TRIPLE SUPERPHOSPHATE with 17.75 mg Cd/kg fertilizer was about 5 times higher than CADMIUM concentration in native rock phosphate with 3.05 mg Cd/kg fertilizer. LEAD concentrations in imported TRIPLE SUPERPHOSPHATE and native rock phosphate were found 0.932 and 1.05 mg Pb/kg respectively and no statistically significant difference was observed between two fertilizers. Application of TRIPLE SUPERPHOSPHATE had the greatest effect on shoot CADMIUM concentration (10.5%) compared to the PHOSPHATE ROCK. Using THIOBACILLUS increased significantly shoot CADMIUM concentration (6%) and CADMIUM translocation factor. Application of phosphate fertilizers decreased LEAD concentration in shoot and the highest LEAD concentration was observed in the control treatment.Conclusion: In general, the results indicated that the application of phosphate fertilizers not only didn’t cause LEAD transmission to the plant but also inhibited LEAD entrance to the plant, but the use of sulfur and THIOBACILLUS along with phosphate fertilizers increased LEAD uptake in plant in comparison with application of only phosphate fertilizers, so that, it was classified with control treatment in one group. Imported triple super phosphate fertilizer also raised shoot CADMIUM concentration up to 10.5% in compared to phosphate soil because of high CADMIUM contamination. A very little CADMIUM pollution in phosphate soil suggests the good quality of phosphate soil sources in our country compared to imported TRIPLE SUPERPHOSPHATE. However, further studies in this context, will provide more specific results.
