Abstract
AbstractConventional agriculture has played significant role in ensuring food supply to the continuously growing population of the world. Soil management strategies in conventional agriculture are largely dependent on chemical fertilizers and pesticides which have caused a serious threat to environment, human, and animal health. Presently governments and farmers are adopting organic farming practices to maintain/improve soil health to achieve sustainability in agriculture production. Organic farming not only ensures the health of the soil but also improves the quality of food. Release of nutrients from organic inputs is a result of mineralization process mediated by plant growth-promoting microbes (PGPM). Microbes stimulate the growth of the plants by increasing the nutrient availability, growth hormone production disease suppression. Exploitation of these plant growth-promoting microbes has supreme importance in organic agriculture. PGPM helps the crop plants to perform better specially under biotic and abiotic stress. Organic farming which excludes the application of agrochemicals is entirely dependent on biological inputs for nutrient and pest management. This chapter includes the role of microbes in organic farming in relation to various aspects such as input preparation, role in increasing nutrient availability, tolerance against biotic and abiotic stress, plant defense mechanism.KeywordsAgriculture sustainabilityCarbon sequestrationMineralizationOrganic farmingPGPMSoil health
