“…As human population growth is estimated to reach 9 billion people by 2050 (United Nations, 2014) and the salinized areas increase at a rate of 10% per year, it appears that by 2050 more than 50% of arable land will be salinized (Jamil, Riaz, Ashraf, & Foolad, 2011). Therefore, it's important to recover these areas to make them productive again and contribute to the increase of arable land in semiarid regions (Leal et al., 2019) in order to meet the food demand around the globe.…”

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

“…According to [11], the inhibitory effect of salinity stress on the growth and productivity of different crops depends on several factors, such as salt concentration in the soil solution, time interval, plant species, plant growth stage, gas exchange properties, photosynthetic pigments, and environmental conditions. Therefore, it is important to explore sustainable management practices to reduce the harmful effect of this problem through genetic techniques, breeding programs of crops for salinity tolerance, soil conditioners, and biological products [12][13][14]. Within these practices, beneficial microorganisms (plant growth-promoting rhizobacteria, PGPR) play an important role in ameliorating salt stress and the ability to release nutrients from organic and inorganic forms to soluble forms, which appears to be a promising process for enhancing the tolerance of crops to salinity [15].…”

The use of phosphogypsum (PG) and plant growth-promoting rhizobacteria (PGPR) for agricultural purposes are good options to improve soil properties and increase crop yield. The objective of this study was to investigate the effect of different rates of PG (ton ha−1; 0 (PG1), 3 (PG2), 6 (PG3), and 9 (PG4)) combined with PGPR inoculation (Azospirillum lipoferum (control, T1), A. lipoferum + Bacillus coagulans (T2), A. lipoferum + B. circulance (T3), and A. lipoferum + B. subtilis (T4)) on soil properties, plant physiology, antioxidant enzymes, nutrient uptake, and yield of maize plants (Zea mays L., cv. HSC 10) grown in salt-affected soil. Over two growing seasons, 2019 and 2020, field experiments were conducted as a split-plot design with triplicates. The results show that applying PG (9 ton ha−1) and co-inoculation (A. lipoferum + B. circulance) treatment significantly increased chlorophyll and carotenoids content, antioxidant enzymes, microbial communities, soil enzymes activity, and nutrient contents, and showed inhibitory impacts on proline content and pH, as well as EC and ESP, thus improving the productivity of maize plant compared to the control treatment. It could be concluded that PG, along with microbial inoculation, may be an important approach for ameliorating the negative impacts of salinity on maize plants.

“…Considerando que o aumento populacional é estimado para alcançar 9 bilhões de pessoas até 2050 (United Nations, 2014), que as áreas salinizadas aumentam a uma taxa de 10% ao ano e que as estimativas indicam que até 2050 mais de 50% das terras aráveis serão salinizadas (Jamil et al, 2011), há a necessidade de recuperar estas áreas para torná-las produtivas novamente, contribuindo para o aumento de terras cultiváveis em regiões semiáridas (Leal et al, 2019). Desta forma, é necessário o desenvolvimento de tecnologias alternativas rápidas e eficientes para manejar plantas em solos salinos (Liu et al, 2019).…”
