  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

    Most soil conditions across the world can provide plants adapted to that climate and soil with sufficient nutrition for a complete life cycle, without the addition of nutrients as fertilizer. However, if the soil is cropped it is necessary to artificially modify soil fertility through the addition of fertilizer to promote vigorous growth and ...

  4. Physical properties of soil - Wikipedia

    en.wikipedia.org/wiki/Physical_properties_of_soil

    Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.

  5. Soil ecology - Wikipedia

    en.wikipedia.org/wiki/Soil_ecology

    Soil is made up of a multitude of physical, chemical, and biological entities, with many interactions occurring among them. It is a heterogenous mixture of minerals and organic matter with variations in moisture, temperature and nutrients.

  6. Soil - Wikipedia

    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 ...

  7. Breeding for drought stress tolerance - Wikipedia

    en.wikipedia.org/wiki/Breeding_for_drought...

    If plants do not receive adequate rainfall or irrigation, the resulting dehydration stress can reduce growth more than all other environmental stresses combined. Drought can be defined as the absence of rainfall or irrigation for a period of time sufficient to deplete soil moisture and cause dehydration in plant tissues. Dehydration stress ...

    “Since these nutrients dissolve in water, boiling or simmering foods like broccoli, spinach or bell peppers can lead to a loss of these vitamins,” Rizwan Abid tells EatingWell.

  9. Nutrient cycle - Wikipedia

    en.wikipedia.org/wiki/Nutrient_cycle

    The bodies of dead worms passively contribute mineral nutrients to the soil. The worms also mechanically modify the physical structure of the soil as they crawl about (bioturbation) and digest on the molds of organic matter they pull from the soil litter. These activities transport nutrients into the mineral layers of soil.
