Abstract

Restoring marginal land is crucial in order to meet current food requirements and for sustainable agriculture. Soils that are uncultivated due to some physical and chemical parameters or having harsh environmental conditions are known as marginal lands. These lands comprise of flood-prone soils, saline, and acidic soils, contaminated soils, degraded soils, drought-affected soils, and nutrient-deficient soils. In the current years, the restoration of the prospective marginal lands has gained attention due to the arising new microbial technologies. Microbial remediation is recognized as one of the best technology to reclaim the marginal lands because certain microbes can enrich soils as well as plant growth even in a harsh climatic condition also. Recent studies showed that the use of plant growth-promoting rhizobacteria and arbuscular vesicular mycorrhiza technology can help improve soil properties. Though to restore and reclaim marginal lands for higher crop productivity, amendments of organic fertilizers are also necessary.
