Resumen

Saline soils are caused by different problems such as salinization, acidification, erosion and various human activities that disturb soil quality. The phytoremediation tests were carried out in 50 m x 50 m soil plots for each plant species, prioritizing only the growth of Sesuvium portulacastrum and Aptenia cordifolia in the respective plots. The treatment was carried out in situ for a period of 63 days, monitoring at times of 0, 30 and 63 days after planting, in order to obtain the reduction values. The results showed that, Sesuvium portulacastrum was able to reduce soil salinity from 5.58 to 3.30 mS/cm and from 5.58 to 1.06 mS/cm in 30 and 63 days, respectively. While, Aptenia cordifolia was able to reduce salinity from 5.51 to 4.60 mS/cm and from 5.51 to 3.6 mS/cm in 30 and 63 days, respectively. This highlights the potential of both plants, reaching a salinity reduction of 81 % with Sesuvium portulacastrum. Therefore, it is concluded that the use of both plants are efficient methods to reduce salinity in saline soils, and can be applied in different agricultural areas, considering their adaptability and growth.
