Book Description
This book discusses the role of salt in current agricultural approaches, including the low salt tolerance of agricultural crops and trees, impact of saline soils, and salt-resistant plants. Halophytes are extremely salt tolerant plants, which are able to grow and survive under salt at concentrations as high as 5 g/l by maintaining negative water potential. The salt-tolerant microbes inhabiting the rhizospheres of halophytes may contribute to their salt tolerance, and the rhizospheres of halophytic plants provide an ideal opportunity for isolating various groups of salt-tolerant microbes that could enhance the growth of different crops under salinity stress. The book offers an overview of salt-tolerant microbes' ability to increase plant tolerance to salt to facilitate plant growth, the potential of the halophytes’ rhizospheres as a reservoir of beneficial salt-tolerant microbes, their future application as bio-inoculants in agriculture and a valuable resource for an alternative way of improving crop tolerance to salinity and promoting saline soil-based agriculture. This special collection of reviews highlights some of the recent advances in applied aspects of plant (halophytes)-microbe interactions and their contribution towards eco-friendly approaches saline soil-based agriculture.

Book Description
This edited volume focuses on the characterization, reclamation, bioremediation, and phytoremediation of salt affected soils and waterlogged sodic soils. Innovative technologies in managing marginal salt affected lands merit immediate attention in the light of climate change and its impact on crop productivity and environment. The decision-making process related to reclamation and management of vast areas of salt affected soils encompasses consideration of economic viability, environmental sustainability, and social acceptability of different approaches. The chapters in this book highlight the significant environmental and social impacts of different ameliorative techniques used to manage salt affected soils. Readers will discover new knowledge on the distribution, reactions, changes in bio-chemical properties and microbial ecology of salt affected soils through case studies exploring Indian soils. The contributions presented by experts shed new light on techniques such as the restoration of degraded lands by growing halophyte plant species, diversification of crops and introduction of microbes for remediation of salt infested soils, and the use of fluorescent pseudomonads for enhancing crop yields.

Book Description
Soil salinity affects an estimated one billion hectares worldwide. Excess salinity inhibits plant growth, limiting crop production. This is caused by osmotic stress in saline soil, nutrient imbalance and specific ion toxicity. There have been many methods of remediation investigated, including excavation, soil washing and phytoremediation. Phytoremediation involves the growth of plants on impacted soils to degrade or sequester contaminants. The remediation of salts relies on the uptake of ions into plant biomass where the salt is sequestered and the biomass can then be harvested. This method removes the salt from the site and leaves the top soil in place, which aids in revegetation after site remediation is completed. Plant-growth promoting rhizobacteria (PGPR) improves plant growth by lowering the levels of stress ethylene within the plant, thereby increasing the biomass available to sequester ions. The objectives of this research were to investigate the efficiency of phytoremediation of salt impacted soils in field remediation sites.

Book Description
This volume explains the recent findings on the mutualistic plant–microbe interactions and how they can be utilized for sustainable agriculture practices including land reclamation. The book covers mainly plant growth promoting microorganisms (PGPMs) including both the symbiotic bacteria and fungi and their role in mobilization of nutrients, providing protection to the crops from phytopathogens and abiotic stresses. PGPMs play important roles in survival and health of the plant. These useful microorganisms provide plants with nutrients, protect them from pathogens and help them combat abiotic stresses. It is important that these mutualistic interactions between plant and soil microbes are well understood so as to develop reliable products in the form of biostimulants and biopesticides, as well as managing biotic and abiotic stresses in crops. Apart from enhancing crop productivity plant–microbe interactions can also perform activities such as reclamation of degraded lands, degradation of pollutants and remediation of saline or marginal lands. This book is of interest to teachers, researchers, plant scientists and microbiologists. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, microbiology, biotechnology, ecology, soil science and environmental sciences.

Book Description
Soil salinity is a widespread problem that limits crop yield throughout the world. The accumulation of soluble salts in the soil can inhibit plant growth by increasing the osmotic potential of interstitial water, inducing ion toxicity and nutrient imbalances in plants. Over the last decade, considerable effort has been put into developing economical and effective methods to reclaim these damaged soils. Phytoremediation is a technique that uses plants to extract, contain, immobilize and degrade contaminants in soil. The most common process for salt bioremediation is phytoextraction which uses plants to accumulate salt in the shoots, which is then removed by harvesting the foliage. As developing significant plant biomass in saline soils is an issue, a group of free-living rhizobacteria, called plant growth promoting rhizobacteria (PGPR), can be applied to plant seeds to aid plant growth by alleviating salt stress. The principle objective of this research was to test the efficacy of PGPR in improving the growth of plants on salt-impacted soils through greenhouse and field studies. In this research, previously isolated PGPR strains of Pseudomonas putida UW3, Pseudomonas putida UW4, and Pseudomonas corrugata CMH3 were applied to barley (Hordeum valgare C.V. AC ranger), oats (Avena sativa C.V. CDC baler), tall wheatgrass (Agropyron elongatum), and tall fescue (festuca arundinacea C.V. Inferno). PGPR effects on plant growth, membrane stability, and photosynthetic activity under salt stress were examined.

Book Description
This book highlights the approaches for achieving trans-disciplinary research integration for “semi-arid dryland agriculture systems” under changing climates, while also identifying the elements of a collaborative research agenda that are needed to advance global food security. The book emphasizes climate change being a reality and how drylands are bearing the brunt in diverse ways. The major impact of dryland agriculture is on communities that need to: avoid the short- and long-term impacts of the changing climate; adapt strategies that can minimize these impacts; and be able to mitigate climate change, for which they need climate smart interventions. These interventions are only realized through knowledge and experience sharing among stakeholders from different sectors and backgrounds. It is in this context that the publication was seen as a necessity in order to bring together ideas that will transform lives and build adaptation capacities, thereby providing the much-needed products in communities leading to development
