“…(BA): Due to the impact of salinization leaving soils unvegetated or poorly covered, BA has therefore emerged as an alternative option [4]. It was introduced in 1997 by the IAEA (International Atomic Energy Agency) via a project in collaboration with INRA (National Institute of Agronomic Research) and ORMVA (Regional Office for Agricultural Development) of Tafilalet [28]. This first test study was carried out in Aïn El Atti, where 11 species of trees and shrubs, notably Ecalyptus camaldulensis and Atriplex lentiformis, were irrigated with highly salinized water (10 g/L).…”

“…Other studies were conducted in other regions impacted by salinization. For example, the case of Foum El Oued where soil and water are salinized, alternative species are tested, such as Quinoa, Pearl millet, barley, Panicum Blue, etc., and have shown very high tolerance to salinity [28]. DS: Water salinization is observed in most hydraulic basins of Morocco.…”

“…Devi et al (2016) characterized Suaeda fruticosa and Atriplex lentiformis as salt hyperaccumulator species. Hirich et al (2021) reported that the introduction of alternative crops, such as blue panicum, quinoa and sesbania, reduces the impacts of soil and water salinity. Moreover, the reclamation of saline and sodic soils can be achieved using integrated soil reclamation approach including physical, chemical, hydrological and biological methods, based on the scientific diagnostics of both the salinity and sodicity, such as PG (Smaoui-Jardak et al, 2017;El Mejahed et al, 2020), and G (Makoi and Verplancke, 2010;Zaman et al, 2018).…”

Salinity and sodicity are the most agricultural challenges in arid and semi-arid regions. A pot experiment was undertaken, to evaluate the effect of Phosphogypsum (PG) and Gypsum (G), to remove salts, nutrients and trace elements in leached water from saline and saline-sodic soils. In order to determine the efficiency and safety of these amendments, as an affordable strategy, for overcoming salinity and sodicity stress. The PG at 0, 15, 30 and 45 t/ha and G at 15 t/ha were mixed with the upper 9 cm soil in the pot before being leached. The soils were collected from Sed El Masjoune and Sidi El Mokhtar areas of morocco with ECe of 140.6 mS/cm and 11.7 mS/cm respectively. The highest doses of PG (≥30 t/ha) removed significant amount of salts and nutrients. Calcium sulfate supplies calcium ions to replace salt ions (sodium, especially). The replaced salts are leached from the soil. The PG was more efficient compared to G in terms of salts leaching. Quantities of trace elements in the leachate, for most analyzed elements, were below the recommended limits of drinking and irrigation water. Because the experiment’s alkaline conditions (basic water and soil) reduce the solubility and mobility of trace elements. The amendment application did not affect saturation index (SI) of the main minerals. However, water passing through the soil increased the SI. which could result in groundwater mineral precipitation.

“…Biosaline agriculture can be a judicious solution to bring salt-affected land back to production through the introduction of salt-tolerant and halophytic crops. Crops such as blue panicum, halophytic grasses, quinoa, sesbania, and barley showed great performance, and have already been adopted by farmers [1]. The application of organic amendments is one of the best practices used to cope with salinity and water stress [2].…”
