  2. Soil organic matter - Wikipedia

    en.wikipedia.org/wiki/Soil_organic_matter

    The benefits of SOM result from several complex, interactive, edaphic factors; a non-exhaustive list of these benefits to soil function includes improvement of soil structure, aggregation, water retention, soil biodiversity, absorption and retention of pollutants, buffering capacity, and the cycling and storage of plant nutrients.

  3. Decomposition - Wikipedia

    en.wikipedia.org/wiki/Decomposition

    Decomposition is largely inhibited during advanced decay due to the loss of readily available cadaveric material. [15] Insect activity is also reduced during this stage. [ 16 ] When the carcass is located on soil, the area surrounding it will show evidence of vegetation death. [ 15 ]

  4. Aspergillus fumigatus - Wikipedia

    en.wikipedia.org/wiki/Aspergillus_fumigatus

    Aspergillus fumigatus, a saprotroph widespread in nature, is typically found in soil and decaying organic matter, such as compost heaps, where it plays an essential role in carbon and nitrogen recycling. [1] Colonies of the fungus produce from conidiophores; thousands of minute grey-green conidia (2–3 μm) which readily become airborne.

  5. Detritus - Wikipedia

    en.wikipedia.org/wiki/Detritus

    In terrestrial ecosystems detritus is present as plant litter and other organic matter that is intermixed with soil, known as soil organic matter. The detritus of aquatic ecosystems is organic substances suspended in the water and accumulated in depositions on the floor of the body of water ; when this floor is a seabed , such a deposition is ...

  6. Organic matter - Wikipedia

    en.wikipedia.org/wiki/Organic_matter

    Organic matter, organic material, or natural organic matter refers to the large source of carbon-based compounds found within natural and engineered, terrestrial, and aquatic environments. It is matter composed of organic compounds that have come from the feces and remains of organisms such as plants and animals . [ 1 ]

  7. Decomposer - Wikipedia

    en.wikipedia.org/wiki/Decomposer

    In terrestrial environments, decomposition happens mainly in or on soil, and decomposers' activities lead to increased soil fertility. [7] The main nutrients plants have to derive from soils are nitrogen, phosphorus, and potassium, and all three have to be available in forms that are accessible to and absorbable by the plants.

  8. Soil biology - Wikipedia

    en.wikipedia.org/wiki/Soil_biology

    The mineral content of the soil and its heartiful [clarification needed] structure are important for their well-being, but it is the life in the earth that powers its cycles and provides its fertility. Without the activities of soil organisms, organic materials would accumulate and litter the soil surface, and there would be no food for plants ...

  9. Alcaligenes - Wikipedia

    en.wikipedia.org/wiki/Alcaligenes

    Species of Alcaligenes typically occur in soil and water or decaying materials and dairy products. A. faecalis is commonly found in the intestinal tracts of vertebrates, and is found as a harmless saprophyte in 5% – 19% of the human population. [11] Infections from Alcaligenes species are uncommon and largely opportunistic.
