  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 ecology - Wikipedia

    en.wikipedia.org/wiki/Soil_ecology

    [10] [11] Soil temperature influences biological and biochemical processes in soil, playing an important role in microbial and enzymatic activities, mineralization and organic matter decomposition. [12] Air is vital for respiration in soil organisms and in plant growth. [13] Both wind and atmospheric pressure play critical roles in soil ...

  4. Plant microbiome - Wikipedia

    en.wikipedia.org/wiki/Plant_microbiome

    The plant microbiome, also known as the phytomicrobiome, plays roles in plant health and productivity and has received significant attention in recent years. [1] [2] The microbiome has been defined as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties.

  5. 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.

  6. Soil - Wikipedia

    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.

  7. Microorganism - Wikipedia

    en.wikipedia.org/wiki/Microorganism

    The combined domains of archaea and bacteria make up the most diverse and abundant group of organisms on Earth and inhabit practically all environments where the temperature is below +140 °C (284 °F). They are found in water, soil, air, as the microbiome of an organism, hot springs and even deep beneath the Earth's crust in rocks. [48]

  8. 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.

  9. 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.
