Plant treatment of lead-contaminated soil using Dodonnaea viscosa

Abstract

A field experiment was conducted in Al-Zuhoor Private Arboretum from February to April 2022 to find out the best plant treatment to determine the ability of the Dodonnaea viscosato to absorb the element of lead added to the soil. The field experiment was conducted in 6 kg plastic flowerpots (Capacity 6 kg per flowerpot) according to a full random design and at a rate of 7 treatments and 3 replications for each treatment. Results of the field experiment on soil and shoot total revealed that the treatment with the symbol (NSIP) exceeds natural soil with the plant and the addition of bacterial vaccine and the addition of lead element at a concentration of 750 mg / liter. This has achieved the highest percentage of removal of the lead element amounted to 74.093% in the soil and a percentage of removal in the shoot total 78.513%. Results of the study showed a significant increase in some of the characteristics of the shoot growth in the number of leaves, with the highest number of treatment leaves (SSP) of the sterile soil sterilized with bacterial additive and a concentration of 750 mg/l of lead.
