“…Chlorophyll content has been proved to be an important reference index for plant response to environmental stress, nutrient status and photosynthetic e ciency (Zou et al, 2018). Previous studies have shown that the salinization of soil could adversely affect chlorophyll synthesis by accelerating the degradation of chlorophyll and decreasing the uptake of N (Van Hoorn et al 2001;Liu et al, 2018;Song et al, 2022). Many studies have con rmed that biochar addition increases the chlorophyll through decreased the manufacture of reactive oxygen species and DPPH activity of leaf cells in saline soil (Torabian et al, 2018;Bashir et al, 2020).…”

“…The oxidative stress in crop cells was caused by the accumulation of reactive oxygen species, which was triggered by salt stress (Munns and Tester 2008). These negative effects can cause nutritional disorders, limit the uptake of essential plant nutrients and water, change the structural integrity and function of cell membrane, restrict the leaf photosynthesis, thus reducing the yield (Wong et al 2010; Chaganti and Crohn 2015; Song et al, 2022). Therefore, how to reduce soda saline-alkali stress and promote the growth and development of crops in saline-alkali land have important meaning to ensure food security.…”

Aims Saline-alkali soil seriously restricts the crop growth and production. Biochar addition could alleviate the adverse impacts of saline-alkali stress in crops. However, little information is available on the ionic accumulation and photosynthesis rate of rice in highly saline-alkali paddy fields. This study aimed to evaluated the influence of the peanut shell biochar on leaf ionic concentration, stress physiology indices, photosynthesis related parameters and rice yield in highly saline-alkali paddy field condition. Methods Field experiment was conducted using two nitrogen applied rate treatments (0 and 225 kg N ha− 1) and four biochar applied rate treatments (0%, 1.5%, 3.0% and 4.5% w/w). The field experiment was arranged in a complete randomized design with three replications. Results The results show that peanut shell biochar significantly reduced the leaf Na+ concentration, Na+/K+ ratio, abscisic acid and malondialdehyde concentration of rice, while enhanced leaf K+ content, and improved leaf water status and relative electrical leakage in treatments both with or without N fertilization. Furthermore, peanut shell biochar could provide beneficial effects on chlorophyll content, leaf N content, leaf area index, photosynthetic potential, stomatal conductance, and transpiration rates, which is of great benefit to the enhancement of leaf photosynthesis rate and net assimilation rate of rice population. In addition, the biomass, grain yield and harvested index were remarkably increased. Conclusions These results indicated that peanut shell biochar could effectively ameliorate saline–alkali stress and increase rice yield by regulating of leaf ionic concentration and improving leaf photosynthesis rate.

“…A number of studies show that VC enhanced salinity tolerance and improved the morphological characteristics such as stem and root length, fresh and dry weight of root-shoot, vigor index, leaf area, and dry weight per plant [ 54 , 57 , 58 , 59 ]. It has been reported that VC boosted Na + exclusion and K + accumulation, alleviated stomatal restriction, raised leaf pigment concentrations, improved root activity, decreased oxidative damage in Fountain Grass, and improved salt tolerance [ 60 ]. In addition, VC application in maize and tomato plants under salt stress improved Chl a, Chl b, Total Chl, carotenoids, CAT, POD, and SOD and lowered H 2 O 2 and MDA [ 27 , 61 ].…”

Natural and/or human-caused salinization of soils has become a growing problem in the world, and salinization endangers agro-ecosystems by causing salt stress in most cultivated plants, which has a direct effect on food quality and quantity. Several techniques, as well as numerous strategies, have been developed in recent years to help plants cope with the negative consequences of salt stress and mitigate the impacts of salt stress on agricultural plants. Some of them are not environmentally friendly. In this regard, it is crucial to develop long-term solutions that boost saline soil productivity while also protecting the ecosystem. Organic amendments, such as vermicompost (VC), vermiwash (VW), biochar (BC), bio-fertilizer (BF), and plant growth promoting rhizobacteria (PGPR) are gaining attention in research. The organic amendment reduces salt stress and improves crops growth, development and yield. The literature shows that organic amendment enhances salinity tolerance and improves the growth and yield of plants by modifying ionic homeostasis, photosynthetic apparatus, antioxidant machineries, and reducing oxidative damages. However, the positive regulatory role of organic amendments in plants and their stress mitigation mechanisms is not reviewed adequately. Therefore, the present review discusses the recent reports of organic amendments in plants under salt stress and how stress is mitigated by organic amendments. The current assessment also analyzes the limitations of applying organic amendments and their future potential.

Soil salinization is a common form of land degradation in coastal regions. The Yellow River Delta is a typical coastal saline‐alkali soils distribution region, with saline‐alkali soils accounting for nearly half of the total area of the region. In view of the lack of fresh water in the region, the use of brackish water and biochar made from agricultural waste to improve coastal saline‐alkali soils has a good application prospect, but there are fewer studies on this at present. To explore water conservation, fertilization, and yield enhancement solutions appropriate for saline‐alkali soils in the Yellow River Delta region, this study focused on investigating the impact of biochar addition on the fertility, enzyme activity, and winter wheat yield in saline‐alkali soils under brackish water irrigation conditions. The research was conducted through outdoor potting experiments, utilizing a local moderately saline‐alkali soil as the subject of study. The study design established three different irrigation water mineralization levels (0, 2, and 4 g L−1) during the research. Two types of biochar, wheat straw biochar (WB) and corn straw biochar (CB) were used with four different applications (0, 5, 10, and 20 t ha−1). There were 21 treatments; each replicated three times. The research findings indicated that brackish water irrigation adversely affected soil fertility and soil alkaline phosphatase activity and soil sucrase activity but increased soil urease activity and soil peroxidase activity. In contrast, biochar application improved soil fertility and enzyme activities. The soil fertility and enzyme activities of K2Y10 treatment was higher than that of CK (fresh water, no biochar application) except for soil total nitrogen, which increased by 5.5%–71.2%. While brackish water irrigation decreased winter wheat yield. Biochar application increased winter wheat yield, with the K2Y10 treatment showing the highest yield under brackish water irrigation conditions, and increased by 17.7% compared to CK. In conclusion, the study recommends a combination of water‐saving measures, fertilizer cultivation, and yield increase strategies to improve saline‐alkali soils in the Yellow River Delta region effectively. Specifically, irrigating with 2 g L−1 brackish water and application 10 t ha−1 of CB demonstrated greater efficacy in addressing the challenges of saline‐alkali soils in the region.
