“…There is therefore a dire need to find ways to make these lands productive [5,6]. Many approaches can reclaim saline soils such as engineering, chemical, and biological techniques [2,7]. Using green plants is an efficient, sustainable, and cost-effective practice to improve salt-affected soils' quality [8,9].…”

Vachellia nilotica (L.) P.J.H. Hurther & Mabb. and Dalbergia sissoo Roxb. are two of the most important multipurpose agroforestry tree species of the Indian sub-continent, but their growth in saline soils is greatly reduced. Recently, organic amendments have showed the potential to increase plant growth in salt-affected soils; however, the influence of using these amendments for growing the above-mentioned tree species under saline conditions is not yet quantified. Therefore, an experiment was devised to analyze the interactive effects of organic amendments in saline soils on the growth of V. nilotica and D. sissoo. Under controlled conditions, a pot experiment was conducted in sandy loam saline soils (EC = 20.5 dSm−1). Organic amendments from four diverse sources: farmyard manure (FYM), poultry manure (PM), slurry (SL), and farmyard manure biochar (FYMB) were employed in this study. At the harvesting time, data regarding morphological, physiological, ionic, and biochemical parameters were obtained. The current study results indicated that both tree species reacted differently, but positively, to diverse applied amendments. The maximum increment in total above-ground biomass, total below-ground biomass, and shoot length for V. nilotica (163.8%, 116.3%, and 68.2%, respectively) was observed in FYM amended soils, while the maximum increment for D. sissoo (128%, 86%, and 107%, respectively) was observed in FYMB amended soils, as compared to control. Minimum plant growth of both species was observed in untreated soils (saline soils). Likewise, the maximum potassium ion and minimum sodium ion concentrations were present in the root and shoots of plants (both species) treated with FYMB. The use of organic amendments resulted in decreased concentrations of malondialdehyde and hydrogen peroxide, and increased concentrations of antioxidant enzymes such as SOD, POD, and CAT. Moreover, higher photosynthetic rates and stomatal conductance were observed in the plants grown in amended soils. The findings of this study can be used to include the above-mentioned high-value tree species for future afforestation programs under saline conditions.

“…High salinity in the soil is very detrimental, so mitigation measures must be taken. Various methods to overcome the problem of soil salinity have been developed by researchers, including chemical methods with ameliorant materials (Costa et al, 2018;Gangwar et al, 2020). The process is called amelioration, which means an attempt to improve saline soil by adding ameliorants.…”

Salinity stress is the major abiotic stress for crop production. The purpose of this study was to evaluate the effectiveness of zeolite on improving soil properties, the growth, and yield of Chinese cabbage. This pot experiment was conducted from September to November 2020 at the Research and Teaching Field of the Faculty of Agriculture, consisted of 6 treatment levels, i.e. (1) control, (2) soil + 6.9 g NaCl /10 kg soil, (3) soil + 6.9 g Na2SO4 /10 kg soil, (4) soil + 3.2 g zeolite /10 kg soil, (5) soil + 6.9 g NaCl /10 kg soil + 3.2 g zeolite /10 kg soil, and (6) soil + 6.9 g Na2SO4 /10 kg soil + 3.2 g zeolite /10 kg of soil, and arranged in a completely randomized design with 3 replications. The application of zeolite decreased the EC of salinized soil and increased the soil CEC. NaCl salinity stress reduced plant height (23%), number of leaves (22%), fresh weight of roots (165%), dry weight of roots (170%), stalk length (32%), and plant dry weight (131%), while Na2SO4 salinity stress only reduced the number of leaves (23%). The addition of zeolite to salinized NaCl soil increased stalk length (39%), plant fresh weight (172%), leaf fresh weight (174%), plant dry weight (133%), and leaf dry weight (23%), while to salinized Na2SO4 soil only increased plant dry weight (90%) and leaf dry weight (177%). The overall results show that the addition of zeolite can effectively ameliorate salinity stress due to NaCl.

“…Mangroves are typically tropical fragile coastal ecosystems of inter-tidal zones of river deltas and back water areas (Sanjay et al, 2014). In the recent time, many approaches have been applied to alleviate soil salinity problems (Costa et al, 2018;Gangwar et al, 2020).According to Kuamr and Verma (2019) and Mishra et al, (2019), other available methods includes bioremediation and phytoremediation. The plant growth-promoting rhizobacteria (PGPR) which mostly heterogenous bacteria contribute a lot in remediating salinity which plays a vital role in plant physiological activities.…”

Abstract This study characterized and screened NaCl tolerance in some bacterial isolates from irrigated soil of Bagwai, Kano State, Nigeria. The soil used for the study was sampled from Irrigation sites using random sampling method. The physicochemical properties and bacteriological characteristics of the soil sample were determined using culture, morphological, biochemical and molecular methods. The soil pH and electrical conductivity were 7.33 and 8.02 dSm-1 respectively. The total nitrogen and available phosphorus from the study area were 0.118% and 3.96 mgkg-1 respectively. The organic carbon recorded a very low content of 0.183%. Moisture content was 080% while temperature was found to be 29oC respectively. Bacteria isolated were identified as B subtilis, S rhizophilia and K pneumoniae. Further comfirmation using 16s rRNA sequencing showed the occurrence of Stenotrophomonas rhizophilia SBANHCu 14 (99.55%) and Klebisella pneumoniae GX 14 (98.68%). All the two bacterial isolates were able to tolerate salt concentration up to 20% but optimum tolerance was observed at 5%.
