They take their food (carbohydrate) from the leguminous plants and absorb nitrogen from the atmosphere. Rhizobia, mycorrhizal fungi, actinomycetes, diazotrophic bacteria, and other beneficial microorganisms are all plant-friendly microorganisms that have symbiotic relationships with plant roots (rhizobia, mycorrhizal fungi, actinomycetes, diazotrophic bacteria), support nutrient availability. The mesofauna are somewhat larger and are heterogeneous, including creatures that feed on microorganisms, decaying matter, and living plants. In microbes, the composition of bacteria varies depending on the environment. This has been the main reason for using more green and friendly methods, such as using biofertilizers and biopesticides. They can appear suddenly and disappear in a few years if not grown by their host plants, but they can survive on other hosts. and A.O. Introduction endobj ; Chen, Y.; Li, Y.H.
