Effect of Phosphorus and Organic Compounds on Bioavailability of Chromium (VI) and its Uptake by Pepper

Occurrence of chromium (Cr), particularly Cr (VI), in water and soil has created serious problems for human life and the environment. Its fixation by various methods in contaminated environments has attracted the attention of many researchers. In this regard, in order to investigate the uptake of chromium in red pepper (local cultivar),an experiment was conducted at Faculty of Agriculture, Shahrood University in the greenhouse conditions as randomized complete block design with three replications. The treatments consisted of control, diammonium phosphate, triple super phosphate, alfalfa powder, humic acid, diammonium phosphate alfalfa powder, alfalfa powder triple superphosphate, humic acid ammonium phosphate, triple superphosphate humic acid. Analysis of the results revealed that there were significant differences between treatments with regard to soil solution phosphorus, Cr (VI) (in root, shoot, and soil) and soil pH value (P
