“…On the other hand, the results of the plant transfer correspond to the data on DTPA extractable Cu fraction [72]. However, many researchers questioned the use of organic manures as remediation agents in soil systems, claiming that manures could be a source of contamination as well as remediation [73]. Salt stress increased the uptake of heavy metals by plants grown without compost compared to the amended soils ( Figure 3B and Table 2), leading to the remediation effect of compost in saline soils.…”

The use of saline water for the irrigation of forage crops to alleviate water scarcity has become necessary in semi-arid and arid regions and researchers have been seeking ways to offset the harmful results of soil salinity. Soil amendments with compost, manure and other organic material provide a valuable source of plant nutrients and appear to speed up soil recovery. The aim of this study was to compare the benefits of farmyard manure and a municipal solid waste (MSW) compost (40 mg ha−1) for raising alfalfa (Medicago sativa, cv. Gabès) under salt-water irrigation. Both compost and manure improved plant mineral uptake and growth of alfalfa cultivated in clay soil. Using compost in clay soil increased the content of copper (Cu), cadmium (Cd), and zinc (Zn) in plant tissues compared to manure, while the bio-accumulation factor (BAF) of Cu, Pb and Zn was higher in plants grown with manure compared to MSW compost with salt stress. Compost addition could enhance alfalfa growth under salt stress, which depends on salt doses and can greatly improve the recovery effects in a cost-effective way, although additional amendment type should receive special attention in order to be used as a tool for sustainable agriculture.

“…Cadmium (Cd) is considered one of the most polluting HMs, characterized by a long half-life (Dutta et al 2020). The sources of environmental contamination by Cd are mainly anthropogenic, such as phosphate fertilizers, irrigation with wastewater, metal industries, and heating systems (Sohail et al 2019). Reduced growth, chlorosis, necrosis, phosphorus and nitrogen deficiency, and disturbance of photosynthetic metabolism are the prevalent Cd poisoning-related symptoms (El Rasafi et al 2020;Thind et al 2020).…”

The objective of the present study was to elucidate the mechanism by which oxalic acid (OA) alleviates cadmium (Cd) stress. Chickpea (Cicer arietinum L.) seeds were treated with 200 µM CdCl 2 for 6 days or 3 days followed by the combination 200 µM Cd + 100 µM OA for three additional days. Exogenous OA mitigated the growth inhibition by Cd of both roots and shoots. This positive effect can be attributed to the increased OA exudation from roots and the alleviation of the Cdinduced depletion of endogenous OA in shoots (80% increase versus Cd-stressed). The combination Cd + OA proved to be effective in protecting cell membrane integrity. This beneficial effect was reflected by 36 and 24% decrease in lipoxygenase (LOX) activity in roots and shoots, respectively, and 60% decrease in the accumulation of the harmful aldehyde, 4-hydroxy-2-nonenal (4-HNE) in roots when compared to Cd-treated samples. Besides, OA restored the Cd-imposed disruption of the plasma membrane function. This effect was depicted by an optimal H + -ATPase activity and proton exudation rate. Oxalic acid counteracted the Cd-induced overproduction of hydroxyl radical (OH•) and NADPH-oxidase activity increase, leading to restore a steady cellular redox state. Furthermore, OA modulated the impact of Cd on Cu/Zn-superoxide dismutase (Cu/ Zn-SOD), ascorbate peroxidase (APX), and catalase (CAT) activities in chickpea seedlings. Present results indicate that OA is able to alleviate Cd toxicity by protecting plasma membrane integrity and modulating antioxidant activities. Moreover, our findings shed light on the interplay between plasma membrane H + -ATPase and the accumulation and root exudation of OA.
