  2. Potassium cycle - Wikipedia

    en.wikipedia.org/wiki/Potassium_cycle

    The most abundant ion in plant cells is the potassium ion. [2] Plants take up potassium for plant growth and function. A portion of potassium uptake in plants can be attributed to weathering of primary minerals, but plants can also ‘pump’ potassium from deeper soil layers to increase levels of surface K. [2] Potassium stored in plant matter can be returned to the soil during decomposition ...

  3. Leaching (chemistry) - Wikipedia

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

    Biological substances can experience leaching themselves, [2] as well as be used for leaching as part of the solvent substance to recover heavy metals. [6] Many plants experience leaching of phenolics, carbohydrates, and amino acids, and can experience as much as 30% mass loss from leaching, [5] just from sources of water such as rain, dew, mist, and fog. [2]

  4. Fertigation - Wikipedia

    en.wikipedia.org/wiki/Fertigation

    Accurate placement of nutrient, where the water goes the nutrient goes as well. Ability to "micro dose", feeding the plants just enough so nutrients can be absorbed and are not left to be washed down to storm water next time it rains. Reduction of fertilizer, chemicals, and water needed. Reduced leaching of chemicals into the water supply.

  5. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    The potassium ion (K +) is highly mobile and can aid in balancing the anion (negative) charges within the plant. A relationship between potassium nutrition and cold resistance has been found in several tree species, including two species of spruce. [12] Potassium helps in fruit coloration, shape and also increases its brix. Hence, quality ...

  6. 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 ...

  7. Nutrient cycle - Wikipedia

    en.wikipedia.org/wiki/Nutrient_cycle

    A nutrient cycle (or ecological recycling) is the movement and exchange of inorganic and organic matter back into the production of matter. Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic.

    A cleaning company has been fined $171,000 after federal investigators found 11 children working a "dangerous" overnight shift at a meat processing plant in Iowa.

  9. Leaching - Wikipedia

    en.wikipedia.org/wiki/Leaching

    Leaching is the loss or extraction of certain materials from a carrier into a liquid (usually, but not always a solvent), and may refer to: Leaching (agriculture) , the loss of water-soluble plant nutrients from the soil; or applying a small amount of excess irrigation to avoid soil salinity
