  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

    The total essential plant nutrients include seventeen different elements: carbon, oxygen and hydrogen which are absorbed from the air, whereas other nutrients including nitrogen are typically obtained from the soil (exceptions include some parasitic or carnivorous plants). Plants must obtain the following mineral nutrients from their growing ...

  4. Soil respiration - Wikipedia

    en.wikipedia.org/wiki/Soil_respiration

    Soil respiration is a key ecosystem process that releases carbon from the soil in the form of CO 2. CO 2 is acquired by plants from the atmosphere and converted into organic compounds in the process of photosynthesis. Plants use these organic compounds to build structural components or respire them to release energy.

  5. Root - Wikipedia

    en.wikipedia.org/wiki/Root

    Researchers have tested whether plants growing in ambient conditions would change their behavior if a nearby plant was exposed to drought conditions. [43] Since nearby plants showed no changes in stomatal aperture researchers believe the drought signal spread through the roots and soil, not through the air as a volatile chemical signal. [44]

  6. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    In plants, algae, and cyanobacteria, photosynthesis releases oxygen. This oxygenic photosynthesis is by far the most common type of photosynthesis used by living organisms. Some shade-loving plants (sciophytes) produce such low levels of oxygen during photosynthesis that they use all of it themselves instead of releasing it to the atmosphere. [12]

    They do not need soil to grow, absorbing moisture and nutrients through little scale-like structures, called trichomes, on their surfaces. They grow on branches, tree trunks, and rocks.

  8. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    Soils supply plants with nutrients, most of which are held in place by particles of clay and organic matter [41] The nutrients may be adsorbed on clay mineral surfaces, bound within clay minerals , or bound within organic compounds as part of the living organisms or dead soil organic matter. These bound nutrients interact with soil water to ...

  9. Should You Fertilize Houseplants in Winter? Here's When to ...

    Because plants don’t absorb nutrients as readily in winter as they do in summer, fertilizers are more likely to build up in the soil at this time of the year. If you do decide to fertilize your ...
