  2. Soil microbiology - Wikipedia

    en.wikipedia.org/wiki/Soil_Microbiology

    Soil microorganisms can be classified as bacteria, actinomycetes, fungi, algae and protozoa. Each of these groups has characteristics that define them and their functions in soil. [6] [7] Up to 10 billion bacterial cells inhabit each gram of soil in and around plant roots, a region known as the rhizosphere.

  3. Soil biology - Wikipedia

    en.wikipedia.org/wiki/Soil_biology

    Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface.

  4. Agricultural microbiology - Wikipedia

    en.wikipedia.org/wiki/Agricultural_microbiology

    Agricultural microbiology is a branch of microbiology dealing with plant-associated microbes and plant and animal diseases. It also deals with the microbiology of soil fertility, such as microbial degradation of organic matter and soil nutrient transformations.

  5. Phyllosphere - Wikipedia

    en.wikipedia.org/wiki/Phyllosphere

    Interactions between the host plant and phyllosphere bacteria have the potential to drive various aspects of host plant physiology. [ 8 ] [ 2 ] [ 9 ] However, as of 2020 knowledge of these bacterial associations in the phyllosphere remains relatively modest, and there is a need to advance fundamental knowledge of phyllosphere microbiome dynamics.

  6. Soil ecology - Wikipedia

    en.wikipedia.org/wiki/Soil_ecology

    Soil is made up of a multitude of physical, chemical, and biological entities, with many interactions occurring among them. It is a heterogenous mixture of minerals and organic matter with variations in moisture, temperature and nutrients.

    en.wikipedia.org/wiki/Soil

    Some nitrogen originates from rain as dilute nitric acid and ammonia, [44] but most of the nitrogen is available in soils as a result of nitrogen fixation by bacteria. Once in the soil-plant system, most nutrients are recycled through living organisms, plant and microbial residues (soil organic matter), mineral-bound forms, and the soil solution.

  8. Rhizosphere - Wikipedia

    en.wikipedia.org/wiki/Rhizosphere

    The diagram on the right illustrates that rhizosphere microorganisms like plant-growth-promoting bacteria (PGPB), arbuscular mycorrhizal fungi (AMF), and fungi from the genus Trichoderma spp. can establish beneficial interactions with plants, promoting plant growth and development, increasing the plant defense system against pathogens ...

  9. Root microbiome - Wikipedia

    en.wikipedia.org/wiki/Root_microbiome

    The root microbiome (also called rhizosphere microbiome) is the dynamic community of microorganisms associated with plant roots. [1] Because they are rich in a variety of carbon compounds, plant roots provide unique environments for a diverse assemblage of soil microorganisms, including bacteria, fungi, and archaea.
