“…Biomass plays a role in the stable adsorption of exogenous organic acids into the soil and uses the unique water retention and nutrient metabolism characteristics given by their own physical and chemical structure; together with the function of organic acids, biomass also generates added value for the formation of the physical and chemical properties and microbial diversity of saline–alkaline soil ( Abd El-Mageed et al., 2020 ; Abd El-Mageed et al., 2021 ). The effects of different organic acids and biomass materials on soil nutrient turnover and water–salt movement can lead to changes in the composition, structure, and function of soil microbial communities ( Yao et al., 2021 ; Zhang et al., 2020a ); such complex changes will be reflected back to plant productivity and the soil nutrient cycle through downward control ( Lu et al., 2020 ; Tiwari et al., 2022 ). The process and role of soil microbial diversity in regulating the feedback of “salt-tolerant herbage—coastal saline–alkaline soil” will be further studied in the future.…”

IntroductionIn coastal saline lands, organic matter is scarce and saline stress is high. Exploring the promotion effect of intervention with organic acid from biological materials on soil improvement and thus forage output and determining the related mechanism are beneficial to the potential cultivation and resourceful, high-value utilization of coastal mudflats as back-up arable land.MethodThree exogenous organic acids [humic acid (H), fulvic acid (F), and citric acid (C)] were combined with four kinds of biomass materials [cottonseed hull (CH), cow manure (CM), grass charcoal (GC), and pine needle (PN)] and applied to about 0.3% of medium-salt mudflat soil. The salinity and nutrient dynamics of the soil and the growth and physiological differences of sweet sorghum at the seedling, elongation, and heading stages were observed under different treatments to screen for efficient combinations and analyze the intrinsic causes and influencing mechanisms.ResultsThe soil salinity, nutrient dynamics, and forage grass biological yield during sweet sorghum cultivation in saline soils differed significantly (p < 0.05) depending on the type of organic acid–biomass composite applied. Citric acid–pine needle composite substantially reduced the soil salinity and increased the soil nutrient content at the seedling stage and improved the root vigor and photosynthesis of sweet sorghum by increasing its stress tolerance, allowing plant morphological restructuring for a high biological yield. The improvement effect of fulvic acid–pine needle or fulvic acid–cow manure composite was manifested at the elongation and heading stages.DiscussionCitric acid–pine needle composite promoted the growth of saline sweet sorghum seedlings, and the effect of fulvic acid–pine needle composite lasted until the middle and late stages.

Purpose In coastal saline lands, organic matter is scarce and saline stress is high. Exploring the promotion effect of intervention with organic acid from biological materials on soil improvement and thus forage output and determining the related mechanism. Methods Three exogenous organic acids (humic acid, fulvic acid, and citric acid) were combined with four kinds of biomass materials (cottonseed hull, cow manure, grass charcoal, and pine needle) and applied to about 0.3% of medium-salt mudflat soil. The salinity and nutrient dynamics of the soil and the growth and physiological differences of sweet sorghum at the seedling, elongation, and heading stages were observed under different treatments to screen for efficient combinations and analyze the intrinsic causes and influencing mechanisms. Results The soil salinity, nutrient dynamics, and forage grass biological yield during sweet sorghum cultivation in saline soils differed significantly (p < 0.05) depending on the type of organic acid–biomass composite applied. Citric acid–pine needle composite substantially reduced the soil salinity and increased the soil nutrient content at the seedling stage and improved the root vigor and photosynthesis of sweet sorghum by increasing its stress tolerance, allowing plant morphological restructuring for a high biological yield. The improvement effect of fulvic acid–pine needle or fulvic acid–cow manure composite was manifested at the elongation and heading stages. Conclusions Citric acid–pine needle composite promoted the growth of saline sweet sorghum seedlings, and the effect of fulvic acid–pine needle composite lasted until the middle and late stages.
