A field trial phyto-Fenton process was conducted at a site in Ha Tinh province, Vietnam, to remove pesticides in soil. Magnetite (Fe3O4), fertilizers and elicitors for oxidative burst were added to soil in the different experimental treatments. DDT and isomers were removed in all experimental lots. The removal efficiency was highest in lot B1 (98.4%, final DDT content of 0.09 mg/kg), where only iron materials were added. The conversion of DDT to dichloro-diphenyl-dichloroethylene was more favorable with elicitors present. Soil property analyses indicated that the phyto-Fenton process could occur at neutral soil pH when there are minimal changes in soil organic carbon content and cation exchange capacities. Shifts in the composition of the microbial communities were observed. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9525602/pdf/41598_2022_Article_20687.pdf
