“…Furthermore, PFA directly provides nutrients and also improves soil nutrient availability for the plants. In this study, PFA improved physicochemical properties of the soil under salt stress, such as OM, NN and AP (Table 1), which is in agreement with the report of Kumar Sootahar et al ( 2019) and Sun et al (2022). The relative abundance and composition of bacterial communities in the rhizosphere soil (A) and root (B) samples at the phylum level, the significance comparisons of bacterial communities in the rhizosphere soil (C) and root (D) samples at the genus level.…”

“…Therefore, the correlations between nutrient status and dominant microorganisms of the rhizosphere soil were evaluated in this study (Figure 6). These results suggested the evolutions of microbial community affected by PFA was closely related to the changes of soil nutrient status (OM, AN, NN, S-UE, S-SC and S-NPT), as supported by some studies (Zheng et al, 2021;Sun et al, 2022;Yin et al, 2022).…”

“…Soil salinity, mainly caused by chaotic fertilization, poor irrigation and anthropogenic pollution, has seriously affected more than 6% of the world’s lands ( Hassani et al., 2020 ; Mukhopadhyay et al., 2020 ). High salinity affects the growth and production of crops by preventing absorbing water and various nutrition elements from the soil ( Mukhopadhyay et al., 2020 ; Sun et al., 2022 ; Zied et al., 2022 ). Citrus belongs to sweet-soil plant that is extremely sensitive to salt ( Mokrani et al., 2020 ; Wei et al., 2020 ).…”

“…Trifoliate orange ( Poncirus trifoliata ) is a widely used rootstock in citrus industry, which is sensitive to salt stress ( Wei et al., 2021 ). Cl - and Na + are the major elements for citrus salt stress, and excessive Cl - and Na + can break the potential balance and increase the permeability of plasma membrane ( Lin et al., 2015 ; Bankaji et al., 2019 ; Sun et al., 2022 ). Under salt stress, many adverse symptoms occur, such as chlorosis, scorching of leaf tip, early leaf falling and even trees dying ( Wu et al., 2010 ; Navarro et al., 2014 ; Syvertsen and Garcia-Sanchez, 2014 ).…”

Salt stress damage to plants has been becoming a global concern for agriculture. The application of potassium fulvic acid (PFA) is a promising strategy to alleviate the damage to plants and improve soil quality. However, the study of PFA on plant growth and rhizosphere microbial community remains limited. In this study, microcosmic experiments were conducted to verify the effect of PFA on citrus. Trifoliate orange (Poncirus trifoliata), the most important citrus rootstock, was used to evaluate the effect of PFA on salt damage. The results showed that PFA significantly increased the contents of chlorophyll a, chlorophyll b and carotenoid by 30.09%, 17.55% and 27.43%, and effectively avoided the yellowing and scorching of leaves under salt stress. Based on the results of two-way ANOVA, the mitigation of salt stress on trifoliate seedlings primarily attributed to the enhancement of protective enzyme activities, K+/Na+ ratio and the contents of soluble sugar, soluble protein and proline. Moreover, PFA enhanced neutral protease (S-NPT), sucrase (S-SC) and urease (S-UE) of rhizosphere soil and improved soil nutrition status. The abundance of Bacillus, a kind of rhizosphere beneficial bacteria, was improved by PFA under salt stress, which was mainly associated with the increased activities of S-NPT, S-SC and S-UE. Overall, the application of PFA showed great potential for the alleviation of salt damage on citrus.

“…Peanut is relatively sensitive to salt and drought stress [ 22 , 23 ]. Usually, improper irrigation and excessive evaporation of soil moisture result in aggravated soil salinization, induces damage to peanut crops [ 24 , 25 ]. Under the changing climate, the frequent and unpredictable drought and cold periods occur during the life cycle of peanut, and the seed yields are negatively impacted [ 26 , 27 ].…”

Background Arbuscular Mycorrhizal Fungi (AMF) are beneficial microorganisms in soil-plant interactions; however, the underlying mechanisms regarding their roles in legumes environmental stress remain elusive. Present trials were undertaken to study the effect of AMF on the ameliorating of salt, drought, and cold stress in peanut (Arachis hypogaea L.) plants. A new product of AMF combined with Rhizophagus irregularis SA, Rhizophagus clarus BEG142, Glomus lamellosum ON393, and Funneliformis mosseae BEG95 (1: 1: 1: 1, w/w/w/w) was inoculated with peanut and the physiological and metabolomic responses of the AMF-inoculated and non-inoculated peanut plants to salt, drought, and cold stress were comprehensively characterized, respectively. Results AMF-inoculated plants exhibited higher plant growth, leaf relative water content (RWC), net photosynthetic rate, maximal photochemical efficiency of photosystem II (PSII) (Fv/Fm), activities of antioxidant enzymes, and K+: Na+ ratio while lower leaf relative electrolyte conductivity (REC), concentration of malondialdehyde (MDA), and the accumulation of reactive oxygen species (ROS) under stressful conditions. Moreover, the structures of chloroplast thylakoids and mitochondria in AMF-inoculated plants were less damaged by these stresses. Non-targeted metabolomics indicated that AMF altered numerous pathways associated with organic acids and amino acid metabolisms in peanut roots under both normal-growth and stressful conditions, which were further improved by the osmolytes accumulation data. Conclusion This study provides a promising AMF product and demonstrates that this AMF combination could enhance peanut salt, drought, and cold stress tolerance through improving plant growth, protecting photosystem, enhancing antioxidant system, and regulating osmotic adjustment.

For the current situation of saline‐alkali soil amelioration, it is urgent to explore a multi‐objective amelioration strategy involving crop income increase and environmental benefits. This study used pine‐needle hydrochar to ameliorate saline‐alkali soil and conducted column and pot experiments to investigate its effects on soil properties and crop growth. And the environmental advantages of hydrochar are evaluated through Life Cycle Assessment (LCA). The electrical conductivity, exchangeable sodium percentage, and pH of saline‐alkali soil ameliorated with hydrochar using the column elution method are reduced by 60%, 58%, and 1.2 pH units, respectively, compared to the original soil. Also, the gene copy number of the ameliorated soil has doubled according to qPCR determination. Pot experiment results show that the root length, fresh weight, and germination rate of wheatgrass are increased by 107, 75, and 20%, respectively. These results demonstrated that the exchange of Na+ with H+ released from hydrochar reduced the soil alkalinity and the viability of organisms is enhanced. Moreover, based on this study's data including the hydrochar dosage and wheatgrass yield, the LCA results showed 3.7 × 109 t CO2e carbon sequestration potential and significant environmental benefits.
