A greenhouse experiment was performed using soil artificially contaminated with As at two doses. Sewage sludge composted with pruning waste was used (40 t/ha) as amendment. After the plants reached the end of their growing cycles, As uptake, plant physiological and biochemical parameters, and As availability and physicochemical properties in soil samples were analyzed. The plant species exhibited different behaviors with compost application. Compared to wheat and irrespective of As doses, barley plants in compost-amended soils showed an enhanced As translocation to the aerial part. Although either species could be used for phytoremediation of As-polluted soils, barley is of greater interest for phytoextraction due to its higher biomass and high As translocation when compost is applied to As-contaminated soil.
