“…Legume‐rhizobia symbiosis is the most effective way of fixing nitrogen, which can add 200–300 kg N ha −1 annually (Unkovich, 2012). It has been reported that inoculation of Rhizobium can meet 80% of the nitrogen requirement of legume crops and improve yields by 15%–30% (Grover et al, 2016). BNF contributes ~30 kg N ha −1 per year to rice production systems (Herridge et al, 2008).…”

Land degradation is one of the most pressing environmental problems of the 21st century particularly due to its impact on global food security and environmental quality through the loss of biodiversity and ecosystem services. Land degradation happens at an accelerated rate and affects regions inhabited by more than one‐third population of the world. This phenomenon resulted in a dramatic reduction in the productivity of cropland and rangeland of world thus threatening the environmental quality and food security. It manifests in various forms such as desertification, soil erosion, sodicity, salinity, heavy metal contamination, pesticide contamination, declining soil fertility, and fate of polycyclic aromatic hydrocarbons. The world now has a real chance for the next generation to grow sustainably and eliminate acute food scarcity. Microbes, as vital elements of soil, play an important role in maintaining soil biological properties and fertility. Due to their multifarious biological functions and metabolic uniqueness, microorganisms can fix or solubilize nutrients, add organic matters to the soil to improve its quality. Many of the microorganisms can produce biological compounds or enzymes, which can degrade or scavenge toxic substances from the soils. In this review, we have discussed in detail how diverse microorganisms can help to restore different types of degraded lands. The limitations in application of microorganisms in restoration of soil health and possible scopes to improve the applicability have also been discussed here.

“…In xerophytic environments, the main factors limiting microbial degradation are water content and the osmotic stress caused by salt and soil alkalinization (Lai et al 2013;Grover et al 2016;McFarlane et al 2016). Little is known regarding the microorganisms associated with H. ritteriana (Soteras et al 2012), although they are a potential source of cellulolytic enzymes that degrade one of the main components of plant organic matter (Saparrat et al 2007).…”

The role of microorganisms in litter degradation in arid and semi-arid zones, where soil and water salinization is one of the main factors limiting carbon turnover and decay, remains obscure. Heterostachys ritteriana (Amaranthaceae), a halophyte shrub growing in arid environments such as "Salinas Grandes" (Córdoba, Argentina), appears to be the main source of organic matter in the area. Little is known regarding the microorganisms associated with H. ritteriana, although they are a potential source of enzymes such as cellulolytic ones, which might be important in biotechnological fields such as bioethanol production using ionic liquids. In the present study, by studying the microbiota growing on H. ritteriana leaf litter in "Salinas Grandes," we isolated the cellulolytic fungus Fusarium equiseti LPSC 1166, which grew and degraded leaf litter under salt stress. The growth of this fungus was a function of the C substrate and the presence of NaCl. Although in vitro the fungus used both soluble and polymeric compounds from H. ritteriana litter and synthesized extracellular β-1,4 endoglucanases, its activity was reduced by 10% NaCl. Based on these results, F. equiseti LPSC 1166 can be described as a halotolerant cellulolytic fungus most probably playing a key role in the decay of H. ritteriana leaf litter in "Salinas Grandes."
