Abstract Semiarid regions’ soils have been degraded by salinization. The use of chemical conditioners makes this management very expensive. As an alternative, organic can be used with plants adapted to the salts and phytoremediation, such as Atriplex nummularia Lindl. This study aimed evaluate phytoremediation in recovery attributes a saline‐sodic soil Brazil Northeast. A was carried out testing A. application (gypsum anionic polymer) (bovine sheep manure), control treatment. experiment conducted for 18 mo sampling at 6, 12, mo. treatments did not modify pH but were effective reducing electrical conductivity. All reduced sodium adsorption ratio exchangeable percentage. efficient improve attributes, suggesting these techniques degradation Our also suggests that local seasonal patterns physical characteristics influence effectiveness on extraction dynamics salts. Phytoremediation may complementary produced farm, making more sustainable.
