  2. Hydraulic redistribution - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_redistribution

    Hydraulic redistribution is a passive mechanism where water is transported from moist to dry soils via subterranean networks. [1] It occurs in vascular plants that commonly have roots in both wet and dry soils, especially plants with both taproots that grow vertically down to the water table, and lateral roots that sit close to the surface.

  3. Hydric soil - Wikipedia

    en.wikipedia.org/wiki/Hydric_soil

    Soils with these unique properties are called hydric soils, and although they may occupy a relatively small portion of the landscape, they maintain important soil functions in the environment. [ 1 ] The plants found in hydric soils often have aerenchyma , internal spaces in stems and rhizomes, that allow atmospheric oxygen to be transported to ...

  4. Hygrophyte - Wikipedia

    en.wikipedia.org/wiki/Hygrophyte

    Plants that are hydrophytes (aquatic plants) live within aquatic environments including lakes, streams, ponds, and oceans. While plants that are hygrophytes grow on wet soils, [4] both types of plants are adapted to growing in soils that are low-oxygen (anaerobic) environments where there is extended periods of water saturation or flooding. The ...

  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. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    Due to the plants continuous fight against gravity, plants typically mature much more quickly than when grown in soil or other traditional hydroponic growing systems. [55] Because rotary hydroponic systems have a small size, they allow for more plant material to be grown per area of floor space than other traditional hydroponic systems.

  7. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .

  8. Soil moisture - Wikipedia

    en.wikipedia.org/wiki/Soil_moisture

    A study of a single winter rye plant grown for four months in one cubic foot (0.0283 cubic meters) of loam soil showed that the plant developed 13,800,000 roots, a total of 620 km in length with 237 square meters in surface area; and 14 billion root hairs of 10,620 km total length and 400 square meters total area; for a total surface area of ...

  9. Leaching (agriculture) - Wikipedia

    en.wikipedia.org/wiki/Leaching_(agriculture)

    soil type and structure. For example, sandy soil holds little water while clay soils have high water-retention rates; the amount of water used by the plants/crops; how much nitrate is already present in the soil. [3] The level of nitrous oxide (N 2 O) in the Earth's atmosphere is increasing at a rate of 0.2 to 0.3% annually.
