“…Our results also concur with those of (Barra et al, 2019;Ouyang et al, 2013;Trivedi et al, 2017) who found that the application of composted poultry manure, organic fertilizer, and bio-fertilizers inoculation enhances the benefit of P-fertilization led to the increase of available P in saline-sodic soils. This increase in available P is due to the reduction in pH as a result of organic matter decomposition.…”

Abstract. In Egypt, the total area of agricultural land is 3.36 million acres, which is 3.8 % of the entire territory of the country. One of the main obstacles to agricultural production in Egypt is soil salinization and degradation. Therefore, saline-sodic soil reclamation in arid regions is highly relevant. This study aimed to use Azospirillum inoculation with eco-friendly organic wastes for free remediation of saline-sodic soils. In this work nine treatments included two levels of spent grain (S1 and S2), two levels of compost (C1 and C2), a mix of both sources (C1S1), one level of Azospirillum (A1), a mix of both sources with Azospirillum (A1S1 and A1C1) and an untreated control. The treatments were previously incubated with soil at field capacity for five months under laboratory conditions at 28 °C. The most relevant chemical and biological parameters were analysed every month for five months. Results indicate that Azospirillum inoculation with spent grain increased soil organic carbon (SOC), dehydrogenase and urease enzymes, micro-nutrients (Fe2+, Zn2+, Mn2+, Cu2+ and B+), and macro-nutrients (N, P and K); while decreased exchangeable sodium percentage (ESP), pH and EC, by 75 %, 12 %, and 43 % respectively, compared to initial conditions. The significant variation was observed in chemical and biological properties among all treatments in the order of S2 > A1S1 > A1 > C2 > C1S1 > A1C1 > C1 > control. In conclusion, the addition of Azospirillum with spent grain is highly recommended for amelioration of the saline-sodic soil and is more effective compared with compost to remediate saline-sodic soils.

Phosphorus is the second most critical macronutrient after nitrogen required for metabolism, growth, and development of plants. Despite the abundance of phosphorus in both organic and inorganic forms in the soil, it is mostly unavailable for plant uptake due to its complexation with metal ions in the soil. The use of agrochemicals to satisfy the demand for phosphorus to improve crop yield has led to the deterioration of the ecosystem and soil health, as well as an imbalance in the soil microbiota. Consequently, there is a demand for an alternate cost-effective and eco-friendly strategy for the biofortification of phosphorus. One such strategy is the application of phosphate-solubilizing microorganisms which can solubilize insoluble phosphates in soil by different mechanisms like secretion of organic acids, enzyme production, and excretion of siderophores that can chelate the metal ions and form complexes, making phosphates available for plant uptake. These microbes not only solubilize phosphates but also promote plant growth and crop yield by producing plant-growth-promoting hormones like auxins, gibberellins, and cytokinins, antibiosis against pathogens, 1-aminocyclopropane-1-carboxylic acid deaminase which enhances plant growth under stress conditions, improving plant resistance to heavy metal toxicity, and so on. Pyrroloquinoline quinine (pqq) and glucose dehydrogenase (gcd) are the representative genes for phosphorus solubilization in microorganisms. The content presented in this review paper focuses on different mechanisms and modes of action of phosphate-solubilizing microorganisms, their contribution to phosphorus solubilization, growth-promoting attributes in plants, and the molecular aspects of phosphorus solubilization.

“…To date, many studies have investigated biotechnological solutions to counteract the negative effect on crop yield. Since the last 20 years, isolation through culture-dependent techniques and inoculation of cultivable Plant Growth-Promoting Microorganisms (PGPM) have substantially improved plant fitness under laboratory conditions (Adesemoye et al, 2008;Barra et al, 2016Barra et al, , 2019Viscardi et al, 2016). However, the low extraction efficiency of the culture-dependent methods (<1%) and the limited establishment of the microorganisms under field conditions, represent an important limitation for their massive use (Alabouvette et al, 2009;Toju et al, 2018b).…”

In the current scenario of climate change, the future of agriculture is uncertain. Climate change and climate-related disasters have a direct impact on biotic and abiotic factors that govern agroecosystems compromising the global food security. In the last decade, the advances in high throughput sequencing techniques have significantly improved our understanding about the composition, function and dynamics of plant microbiome. However, despite the microbiome have been proposed as a new platform for the next green revolution, our knowledge about the mechanisms that govern microbe-microbe and microbe-plant interactions are incipient. Currently, the adaptation of plants to environmental changes not only suggests that the plants can adapt or migrate, but also can interact with their surrounding microbial communities to alleviate different stresses by natural microbiome selection of specialized strains, phenomenon recently called "Cry for Help". From this way, plants have been co-evolved with their microbiota adapting to local environmental conditions to ensuring the survival of the entire holobiome to improve plant fitness. Thus, the strong selective pressure of native extreme microbiomes could represent a remarkable microbial niche of plant stress-amelioration to counteract the negative effect of climate change in food crops. Currently, the microbiome engineering has recently emerged as an alternative to modify and promote positive interactions between microorganisms and plants to improve plant fitness. In the present review, we discuss the possible use of extreme microbiome to alleviate different stresses in crop plants under the current scenario of climate change.
