  2. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Soil acidification can cause damage to plants and organisms in the soil. In plants, soil acidification results in smaller, less durable roots. [27] Acidic soils sometimes damage the root tips reducing further growth. [28] Plant height is impaired and seed germination also decreases. Soil acidification impacts plant health, resulting in reduced ...

    en.wikipedia.org/wiki/Bokashi_(horticulture)

    The preserve is mixed into soil that has naturally occurring micro-organisms. When water is present (as in the preserve itself or in the soil) the lactic acid progressively dissociates by losing protons to become lactate – the acid's conjugate base or ion salt. [6] Lactate is a fundamental energy carrier in biological processes.

  4. Biological carbon fixation - Wikipedia

    en.wikipedia.org/wiki/Biological_carbon_fixation

    Cyanobacteria such as these carry out photosynthesis.Their emergence foreshadowed the evolution of many photosynthetic plants and oxygenated Earth's atmosphere.. Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide, CO 2) to organic compounds.

  5. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

  6. Seaweed fertiliser - Wikipedia

    This may have critical implications for plant health because the structure of rhizosphere microbial communities can aid in the resistance of plants to soil-borne pathogens. [ 77 ] Other pathogen reductions include the mitigation of carrot foliar fungal diseases following Ascophyllum nodosum treatment and inoculation with the fungal pathogens ...

  7. Chemosynthesis - Wikipedia

    en.wikipedia.org/wiki/Chemosynthesis

    Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...

  8. Freshwater acidification - Wikipedia

    en.wikipedia.org/wiki/Freshwater_acidification

    Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir. [1]

  9. Soil respiration - Wikipedia

    en.wikipedia.org/wiki/Soil_respiration

    Researchers will grow a C 4 plant on soil that was previously occupied by a C 3 plant or vice versa. By taking soil respiration measurements and analyzing the isotopic ratios of the CO 2 it can be determined whether the soil respiration is mostly old versus recently formed carbon. For example, maize, a C 4 plant, was grown on soil where spring ...
