  2. Zinc deficiency (plant disorder) - Wikipedia

    en.wikipedia.org/wiki/Zinc_deficiency_(plant...

    Maize plants with severe zinc deficiency in the foreground, with healthier plants (planted at the same time) in the background. Zinc deficiency is common in many different types of soil; some soils (sandy soils, histosols and soils developed from highly weathered parent material) have low total zinc concentrations, and others have low plant-available zinc due to strong zinc sorption ...

  3. Zinc sulfate - Wikipedia

    en.wikipedia.org/wiki/Zinc_sulfate

    Zinc sulfate can be used to supplement zinc in the brewing process. Zinc is a necessary nutrient for optimal yeast health and performance, although it is not a necessary supplement for low-gravity beers, as the grains commonly used in brewing already provide adequate zinc.

  4. Wood preservation - Wikipedia

    en.wikipedia.org/wiki/Wood_preservation

    Increasing protection can be applied (in increasing order of attack and treatment) for: exposure to the atmosphere, implantation within soil, or insertion into a marine environment. In the last decade concerns were raised that the chemicals may leach from the wood into surrounding soil , resulting in concentrations higher than naturally ...

  5. In situ chemical reduction - Wikipedia

    en.wikipedia.org/wiki/In_situ_chemical_reduction

    Zero-valent metals are the main reductants used in ISCR. The most common metal used is iron, in the form of ZVI (zero valent iron), and it is also the metal longest in use. However, some studies show that zero valent zinc (ZVZ) could be up to ten times more effective at eradicating the contaminants than ZVI. [3]

  6. Manganese deficiency (plant) - Wikipedia

    en.wikipedia.org/wiki/Manganese_deficiency_(plant)

    If the soil pH is not a problem and there is no manganese in the soil then Foliar feeding for small plants and Medicaps for large trees are both common ways for homeowners to get manganese into the plant. [3] To mitigate issues with manganese deficiency, Manganese oxide and sulfate are components of fertilizers. In the year 2000, an estimated ...

  7. Phytoremediation - Wikipedia

    en.wikipedia.org/wiki/Phytoremediation

    Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]

  8. 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 ...

  9. Iron deficiency (plant disorder) - Wikipedia

    en.wikipedia.org/wiki/Iron_deficiency_(plant...

    Iron deficiency can be avoided by choosing appropriate soil for the growing conditions (e.g., avoid growing acid loving plants on lime soils), or by adding well-rotted manure or compost. If iron deficit chlorosis is suspected then check the pH of the soil with an appropriate test kit or instrument. Take a soil sample at surface and at depth.
