  2. Soil organic matter - Wikipedia

    en.wikipedia.org/wiki/Soil_organic_matter

    Vegetal detritus generally is not soluble in water and, therefore, is inaccessible to plants. It constitutes, nevertheless, the raw matter from which plant nutrients derive. Soil microbes decompose it through enzymatic biochemical processes, obtain the necessary energy from the same matter, and produce the mineral compounds that plant roots are ...

  3. Soil regeneration - Wikipedia

    en.wikipedia.org/wiki/Soil_regeneration

    Native plants should be used whenever possible, [3] their roots help water infiltrate deep into the soil. [4] holistic management stems from the work of Allan Savory, who observes that planned grazing can improve soil health and reverse the effects of desertification by increasing biomass. Researchers dispute the desertification claim.

  4. Mycorrhizal fungi and soil carbon storage - Wikipedia

    en.wikipedia.org/wiki/Mycorrhizal_fungi_and_soil...

    Soil carbon storage is an important function of terrestrial ecosystems. Soil contains more carbon than plants and the atmosphere combined. [1] Understanding what maintains the soil carbon pool is important to understand the current distribution of carbon on Earth, and how it will respond to environmental change.

  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. Soil conditioner - Wikipedia

    en.wikipedia.org/wiki/Soil_conditioner

    Soil conditioners may be used to improve water retention in dry, coarse soils which are not holding water well. The addition of organic material for instance can greatly improve the water retention abilities of sandy soils and they can be added to adjust the pH of the soil to meet the needs of specific plants or to make highly acidic or ...

  7. Bokashi (horticulture) - Wikipedia

    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.

  8. Soil fertility - Wikipedia

    en.wikipedia.org/wiki/Soil_fertility

    The quality of irrigation water is very important to maintain soil fertility and tilth, and for using more soil depth by the plants. [26] When soil is irrigated with high alkaline water, unwanted sodium salts build up in the soil which would make soil draining capacity very poor. So plant roots can not penetrate deep into the soil for optimum ...

  9. Mineralization (soil science) - Wikipedia

    en.wikipedia.org/wiki/Mineralization_(soil_science)

    In soil science, mineralization is the decomposition (i.e., oxidation) of the chemical compounds in organic matter, by which the nutrients in those compounds are released in soluble inorganic forms that may be available to plants. [1] [2] Mineralization is the opposite of immobilization.
