Resumen:
The soil is a system of fundamental importance for the planet, it is vital for any food chain, to the quality of air and water, but in recent decades is afflicted by adverse actions, such as the accumulation of salts in the soil, which harm productivity and environmental balance. The Atriplex nummularia typical family of Chenopodiaceae Australia arises as a source of salvation these contaminated soils, which uses techniques such as phytoextraction to remove soil such salts. This study's main objective is to review literature that addresses how to assess the potential of Atriplex nummularia as plant fitoextratora of salts in the soil of semiarid Paraiba by water stress. Salinity is a major problem that plants face, that significantly reflects the drop in crop yield; these types of problems originate in soils that were used inappropriately for irrigation management. There are techniques used to recover saline soils, phytoextraction is the transfer of the salt into the soil by the roots to the upper parts of the plant where it is removed from the polluted environment. The halophytes, they thrive in soil that has concentrations of salts, the genus Atriplex is a species that has adapted to this semi-arid soils, besides being used as a secondary source of fodder for livestock. Through this literature review it was observed that the use of halophytes such as the Atriplex genus becomes possible and extremely important for the semiarid region.
