In order to reduce heavy metal contamination in agricultural soils, we decided to assess the effect of organic amendments (compost and vermicompost). The work was carried out using sunflower as a fitorremediator. For this purpose, the agricultural soils of the Mantaro and Muqui localities of the Mantaro Valley were used. The results indicate that the soils of the locality of Muqui, contain the greatest amount of Pb and Cd, presenting negative effects on biomass production. The sunflower plant absorbs heavy metals as evidenced by the increased accumulation of lead and cadmium at the root of the sunflower, no significant differences were found between the accumulation of lead in stems and flowers, stems and leaves, for cadmium on the stems and leaves, confirming that the application of organic amendments contributes to solubilizing the Pb and Cd of the soil, in addition to contributing to ...
