“…Among these, an environmentally sound and cost-effective option is the use of beneficial microbes for providing assistance to plants ( Nazli et al, 2020 ). These beneficial bacteria including plant growth promoting rhizobacteria (PGPR) have been widely reported to help crop plants in various kinds of stresses under varying environmental conditions ( Khan et al, 2013 ; Raza et al, 2021 ; Nadeem et al, 2022 ; Rafique et al, 2022 ). These PGPR protect the plant from the negative impact of salinity through a number of their direct and indirect mechanisms and therefore enable it to withstand stress environment ( Zahir et al, 2009 , 2019 ; Fu et al, 2010 ; Glick, 2013 ; Nadeem et al, 2016 ; Ullah et al, 2017 ; Al-Barakah and Sohaib, 2019 ; Rafique et al, 2021 ; Saeed et al, 2021 ; Singh P. et al, 2022 ; Upadhyay and Chauhan, 2022 ; Upadhyay et al, 2022 ).…”

Owing to inconsistent results of a single bacterial strain, co-inoculation of more than one strain under salinity stress could be a more effective strategy to induce salt tolerance. Co-inoculation of more than one bacterial strain could be more effective due to the presence of several growths promoting traits. This study was conducted to evaluate the effectiveness of multi-strains bacterial consortium to promote wheat growth under salinity stress. Several plant growth promoting rhizobacteria (PGPR) had been isolated and tested for their ability to grow in increasing concentrations of sodium chloride (NaCl). Those rhizobacterial strains having tolerance against salinity were screened to evaluate their ability to promote wheat growth in the presence of salinity by conducting jar trials under axenic conditions. The rhizobacteria with promising results were tested for their compatibility with each other before developing multi-strain inoculum of PGPR. The compatible PGPR strains were characterized, and multi-strain inoculum was then evaluated for promoting wheat growth under axenic conditions at different salinity levels, i.e., 2.1 (normal soil), 6, 12, and 18 dS m–1. The most promising combination was further evaluated by conducting a pot trial in the greenhouse. The results showed that compared to a single rhizobacterial strain, better growth-promoting effect was observed when rhizobacterial strains were co-inoculated. The multi-strain consortium of PGPR caused a significant positive impact on shoot length, root length, shoot fresh weight, and root fresh weight of wheat at the highest salinity level in the jar as well as in the pot trial. Results showed that the multi-strain consortium of PGPR caused significant positive effects on the biochemical traits of wheat by decreasing electrolyte leakage and increasing chlorophyll contents, relative water contents (RWC), and K/Na ratio. It can be concluded that a multi-strain consortium of PGPR (Ensifer adhaerens strain BK-30, Pseudomonas fluorescens strain SN5, and Bacillus megaterium strain SN15) could be more effective to combat the salinity stress owing to the presence of a variety of growth-promoting traits. However, further work is going on to evaluate the efficacy of multi-strain inoculum of PGPR under salt-affected field conditions.

“…Etesami et al showed that sulfur oxidation by sulfur bacillus lowers soil pH and promotes phosphate solubilization in the soil, resulting in an increase in plant-available phosphorus. 87 Nadeem et al also showed that elemental sulfur application produces soil acidication which can improve Fe and Mn availability and also facilitate the conversion of more organic-P to inorganic-P. 88 Similarly, studies on sugarcane in Florida, USA by Orem et al have shown that phosphorus release can be modulated by the application of elemental sulfur. 89,90 The authors reported that due to the increase in plant available nutrients, plant growth was improved.…”

“…Although the composting rate can be enhanced through Psolubilizing bacteria (PSB) [25], consequently, bacteria-assisted compost requires less time to make an applicable form of composted RP in soil [26]. On the other hand, different types of microbes (PGPR) produced organic acids that provide a more available form of P [27,28]. Similarly, Nadeem et al [29] suggested that sulfur amended farmyard manure, and when augmented with sulfur-oxidizing bacteria (SOB), produced acidified compost (pH < 2.00), which significantly improved the wheat growth and P availability cultivated under calcareous soils.…”

The demand for a better agricultural productivity and the available phosphorus (P) limitation in plants are prevailing worldwide. Poor P availability due to the high pH and calcareous nature of soils leads to a lower P fertilizer use efficiency of 10–25% in Pakistan. Among different technologies, the use of biologically acidified amendments could be a potential strategy to promote soil P availability and fertilizer use efficiency (FUE) in alkaline calcareous soils. However, this study hypothesized that an acidified amendment could lower soil pH and solubilize the insoluble soil P that plants can potentially uptake and use to improve their growth and development. For this purpose, the test plant Zea mays was planted in greenhouse pots with a recommended dose rate of 168 kg ha−1 of P for selected phosphatic fertilizers, viz., DAP (diammonium phosphate), SSP (single superphosphate), and RP (rock phosphate) with or without 2% of the acidified product and a phosphorus solubilizing Bacillus sp. MN54. The results showed that the integration of acidified amendments and PSB strain MN54 with P fertilizers improved P fertilizer use efficiency (FUE), growth, yield, and P uptake of Zea mays as compared to sole application of P fertilizers. Overall, organic material along with DAP significantly improved plant physiological-, biochemical-, and nutrition-related attributes over the sole application of DAP. Interestingly, the co-application of RP with the acidified product and MN54 showed a higher response than the sole application of DAP and SSP. However, based on our study findings, we concluded that using RP with organic amendments was a more economically and environmentally friendly approach compared to the most expensive DAP fertilizer. Taken together, the current study suggests that the use of this innovative new strategy could have the potential to improve FUE and soil P availability via pH manipulation, resulting in an improved crop productivity and quality/food security.
