Microorganisms play a vital role in agriculture and allied sectors, offering sustainable solutions to enhance productivity and environmental health. Beneficial microbes, such as nitrogen-fixing bacteria, mycorrhizal fungi, and phosphate-solubilizing microorganisms, are integral to improving soil fertility and nutrient cycling. These organisms also support plant growth by producing phytohormones, protecting against pathogens, and enhancing resistance to abiotic stresses like drought and salinity. Nitrogen-fixing bacteria reduce reliance on synthetic fertilizers by biologically converting atmospheric nitrogen into bioavailable forms for crops. Mycorrhizal fungi and phosphate-solubilizing microorganisms improve nutrient acquisition and soil health, supporting plant growth while mitigating chemical input usage. Microbial inoculants, including some biocontrol agents, suppress plant pathogens and pests, providing eco-friendly alternatives to chemical pesticides. In allied sectors, probiotics in livestock farming enhance animal gut health, immunity, and overall productivity, while aquaculture benefits from microbial applications to improve water quality, manage disease, and boost growth. Emerging applications include engineered microbes for carbon sequestration, sustainable biofuel production, and the development of biodegradable plastics. Additionally, microbes play a pivotal role in bioremediation, detoxifying polluted soils and water bodies, and in producing biofertilizers and biopesticides that support eco-friendly farming practices. These innovations underscore the potential of microbial solutions to address global challenges in food security, environmental sustainability, and agricultural resilience. Despite challenges such as strain competition and variable environmental conditions, advancements in microbial biotechnology and the integration of data-driven techniques like artificial intelligence offer promising opportunities.
