“…Nasrin et al [57] showed that the soil-salinity reduces the transformation of secondary P minerals to bioavailable P. In addition, the excessive salinity strongly effects on indigenous microbes and suppresses their activity, diversity and community dissimilarities [58], where the responsible P mobilizing microbes can be affected by salinity. Thus, the P availability for plant largely differs between saline and non-saline soil.…”

Among the environmental factors, soil salinity is one of the most detrimental factors affecting plant growth and productivity. Nutritional-imbalance is also known as one of the negative effects of salinity on plant growth and productivity. Among the essential plant nutrients, phosphorus (P) is a nutrient in which the uptake, transport, and distribution in plant is adversely affected by salinity-stress. Salinity-stress-mediated low a P availability limits the crop production. Adding additional P fertilizer is generally recommended to manage P deficit in saline-soils; however, the low-efficiency of available P fertilizer use in salt-affected soils, restricts P availability, and P fertilizers are also a cause of significant environmental concerns. The application of salinity-tolerant phosphate–solubilizing-bacteria (ST-PSB) can be as a greatly effective and economical way to improve the P availability, and recover the P-deficit in saline-land. This review focuses on soil salinization and its effect on P availability, the mechanisms of P solubilization by ST-PSB, ST-PSB diversity, their role in alleviating salinity stress in plants, the current and future scenarios of their use, and the potential application of this knowledge to manage the sustainable environmental system. According to this review, adding ST-PSB to saline soils could be an alternative for alleviating the negative effects of salinity on plants and may ameliorate salinity tolerance.

“…For example, the presence of high TDS in treated effluents may increase soil salinity at the disposal sites [ 47 ]. The salinity can accumulate at plant roots and cause osmotic effects, thus reducing plant nutrient uptake and consequently its growth [ 48 ]. Additionally, with long-term application of wastewater, TSS and other organics can change the soil properties [ 49 ].…”

In arid regions such as Saudi Arabia, wastewater treatment (WWT) facilities (meeting promulgated standards) need to adapt their continuous performance improvement (CPI) for long-term sustainability. To achieve this, the facilities need to improve their performance to comply with more strict objectives for broader reuse applications of treated effluent. The present research proposes a CPI framework based on performance benchmarking process for the stepwise improvement of WWT facilities. A grey rational analysis water quality index (GWQI) based on exceedance probability was developed. For weights’ estimation of 11 physical, chemical, and biological water quality parameters, the entropy method effectively accommodated the changes in relative importance of the parameters with including additional future reuse applications. For existing effluent reuse scenarios of restricted and unrestricted irrigation, the GWQI values were found consistent with the modified version of the Canadian WQI (GWQI). The indices’ values (ranged between 0 and 100) greater than 80 showed the efficient operation of four WWT plants in the Qassim Region of Saudi Arabia. Two hypothetical CPI scenarios with future reuse applications (fish, livestock drinking, and recreation) showed an overall decline in the average (of four plants) values of the GWQI (97 to 78) and GWQI (85 to 60). GWQI predicted stricter results for the facilities with parameters’ concentrations exceeding the targets with larger margins and was found applicable for the CPI of WWT facilities in arid regions. For existing scenarios, the assessment results suggest the facilities to control and monitor the chlorination practice. For future targets, tertiary treatment needs to be enhanced for desired nutrients and total dissolved solids removal. The proposed CPI framework provides a platform to initiate the performance benchmarking process for WWT facilities at local or regional levels in Saudi Arabia and elsewhere.

“…The reason could be the accumulation of total P because of the organic matter contributed by the crop. Subsequently, it was also fixed in the soil which might be the reason why it barely moved in the soil [15]. However, the decrease of total P in T4 and T5 could be the utilization and crop removal since high amount of organic matter was put in the soil [16].…”

Vigna unguiculata subsp sesquipedalis L. also known as string beans/pole sitao is one of the major vegetable crop produced in the Philippines all year round because of its adaptability to all types of soils except for saline soil. Thus, its response to saline soil amended with vermicompost was determined. Growth and yield of pole sitao in saline soil applied with varying amount of vermicompost was obtained. Level of nitrogen, phosphorus, potassium and pH were also tested before and after vermicompost application. The study was laid out in Randomized Complete Block Design, composed of 5 treatments and replicated 4 times. The treatments were: T1-100% Garden soil, T2-100% Saline soil, T3-75% Saline soil and 25% Vermicompost, T4-50% Saline soil and 50% Vermicompost, and T5-75% Vermicompost and 25% Saline soil. All the data gathered were analyzed using T-test and ANOVA. Generally, vermicompost helps in decreasing soil salinity, increasing potassium content of the soil and increasing root length. To increase pole sitao's yield and biomass, addition of 75% vermicompost to 25% saline soil is recommended.
