The rhizosphere is the narrow region of soil that is directly influenced by root secretions, and associated soil microorganisms known as the root microbiome The rhizosphere contains many bacteria and other microorganisms that feed on sloughed-off plant cells, termed rhizodeposition, and the proteins and sugars released by roots. This symbiosis leads to more complex interactions, influencing plant growth and competition for resources.
➣Soil contains a large variety of life forms.
➣The microscopic organism in soil is called, soil microflora.
➣These are bacteria, fungi, algae, protozoa.
➣Bacteria are of an extremely small size and can occupy relatively small volume, so they are most numerous among microflora.
➣ 1 gram of soil may contain 20,000 different species.
