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.

“…To overcome the cost involved in the commercial iron purchase and to make the process more cost-effective replacement for commercial iron has been studied by various researchers. Previous studies has claimed the application of Iron extracted from natural laterite soil as a Fenton's catalyst in the degradation of organic compounds (Sangami & Manu 2019;Bhaskar et al 2021) However, heterogeneous Fenton's oxidation driving by nano iron catalyst have proven efficient in the degradation of various organic contaminants (She 2010;Chen et al 2017;Sangami & Manu 2018;Bhaskar Basavaraju Manu 2020).…”

Laterite based nano iron particles were synthesized using natural laterite extract as a precursor and Psidium guajava plant extract for its application as Fenton's catalyst in the degradation of triclosan. Chemical digestion method was used for the extraction of iron from laterite soil. Synthesized nano iron catalyst was characterized using SEM – EDS, XRD and FTIR and evaluated for its catalytic application in the Fenton oxidation of triclosan. Maximum triclosan degradation of 69.5 % was observed with nano iron catalyst dosage of 0.1 g/L and hydrogen peroxide dosage of 200 mg/L at acidic pH of 3. Hydrogen peroxide influence on the process was observed with Fenton's oxidation. Role of iron in the process has been accessed by control experiment with no nano catalyst addition in which degradation is considerable low. Fenton's oxidation was compared with conventional Fenton's oxidation driven by a green nano iron catalyst. Study claims the usage of natural laterite iron as a replacement for commercial iron in Fenton's degradation of triclosan. Regeneration and Reusability studies on catalyst were studied and synthesized catalyst was observed to be reusable in three consecutive cycles. Degradation of triclosan in Fenton's oxidation follows pseudo-second order reaction with linear fit.
