“…Phosphatases dephosphorylate organic phosphorus such as phosphomonoesters, diesters, DNA, ATP, and phosphohexose, releasing Pi for absorption into the roots (Robinson et al, 2012;Shen et al, 2011). Plant roots secrete APase to hydrolyze Po, releasing Pi into the rhizosphere (Aslam et al 2022;Li et al 2022), and it has been shown that APase activity increases under phosphate deficiency stress (Li et al 2017;Tran et al 2010). Here we found that OF application induced an increase in APase activity in rice root secretions (Fig.…”

“…As reported by Jarosch et al (2019) APase in soil promotes utilization of organic fertilizer Phosphatase is the main enzyme responsible for hydrolyzing phosphomonoesters, which are the main form of Po in OF (Shen et al 2011). After OF is applied in the field, Po dissolves and diffuses in the soil, this induces APase secretion from plant roots, which hydrolyzes Po and releases Pi in the rhizosphere (Li et al 2022). Inositol hexaphosphate, the main phosphomonoester in OF, is the substrate of APase (Liu et al 2018).…”

Background and aims Organic fertilizer (OF) is beneficial for crop yield and quality, however, most phosphorus in OF are in organic forms, and cannot be utilized until they are hydrolyzed to inorganic phosphate (Pi). Although root-secreted acid phosphatases (APases) play an important role in hydrolyzing organic phosphorus (Po), it is unclear whether they improve the utilization efficiency of OF, and whether purple acid phosphatase (PAP) genes function in plants’ utilization of OF. Methods We report on a 10-year field study of OF application to rice, and the response of rice root-secreted APase activity to organic fertilization. Wild type (WT), OsPAP10c overexpressing, and OsPAP10c deficient rice were used to evaluate the role of this gene on the regulation of root-secreted APase activity in response OF and its subsequent utilization. Results Over 10 years of OF application, the APase activity of rice root secretions increased, over rice that had been fertilized with chemical fertilizer (CF). The APase activity in the rhizosphere soil of OF treated rice increased as well compared to CF treated rice. In PAP10c-OE rice, APase activity in the root secretions was greater than in WT rice, the activity in pap10c rice was less than in WT in OF treatment. Conclusion OF application enhances the APase activity of rice root secretions and improves the APase activity in the rhizosphere soil, which facilitates the hydrolysis of Po in OF. This hydrolysis generated sufficient available Pi for rice growth and production. OsPAP10c positively regulates root-secreted APase activity and Po utilization efficiency in rice in OF treated fields.

“…Biomass has a unique microporous structure and some functional groups that can cut off the continuity of soil capillaries, inhibit the transport and accumulation of water and salts to the upper layers of the soil ( Wu et al., 2021c ), and improve soil porosity and structure by forming iron complexes to increase soil aggregates ( Li et al., 2021 ; Chen et al., 2022 ). In addition, the exogenous application of biomass increases the content of energy substrates and bioactive substances in soil ( Kaur et al., 2005 ; Wong et al., 2009 ), significantly increases soil microbial and enzyme activities, and regulates soil microbial community structure ( Wu et al., 2021a ), thus favorably affecting plant root and aboveground growth and soil ecology ( Chen et al., 2021b ; Li et al., 2022a ). However, the differences in composition and internal mechanism among biomass materials lead to their varying effects on the growth of salt-tolerant forage grasses in saline–alkaline soil and the improvement of the soil itself ( Amini et al., 2016 ).…”

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.
