  2. 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 ...

  3. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    If the water potential is more negative in the plant than the surrounding soils, the nutrients will move from the region of higher solute concentration—in the soil—to the area of lower solute concentration - in the plant. There are three fundamental ways plants uptake nutrients through the root:

  4. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    The effect of pH on a soil is to remove from the soil or to make available certain ions. Soils with high acidity tend to have toxic amounts of aluminium and manganese. [116] As a result of a trade-off between toxicity and requirement most nutrients are better available to plants at moderate pH, [117] although most minerals are more soluble in ...

  5. Soil regeneration - Wikipedia

    en.wikipedia.org/wiki/Soil_regeneration

    The rhizosphere is an "area of concentrated microbial activity close to the root" and where water and nutrients are readily available. [5] Plants exchange carbohydrates for nutrients excreted by the microbes, different carbohydrates support different microbes. [5] Dead plants and other organic matter also feed the variety of organisms in the ...

  6. Immobilization (soil science) - Wikipedia

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

    Immobilization in soil science is the conversion of inorganic compounds to organic compounds by microorganisms or plants by which the compounds become inaccessible to plants. [1] Immobilization is the opposite of mineralization. In immobilization, inorganic nutrients are taken up by soil microbes and become unavailable for plant uptake. [2]

  7. Biological soil crust - Wikipedia

    en.wikipedia.org/wiki/Biological_soil_crust

    The biological soil crust is an integral part of many arid and semi-arid ecosystems as an essential contributor to conditions such as dust control, water acquisition, and contributors of soil nutrients. Biocrust is poikilohydric and does not have the ability to maintain or regulate its own water retention. [14]

    Raw foods can provide valuable nutrients, while cooking may increase the availability of other nutrients, like lycopene in tomatoes or beta carotene in carrots. Mix it up and use a variety of ...

  9. 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. SOM increases ...
