  2. Calcium deficiency (plant disorder) - Wikipedia

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

    Calcium roots loss (blossom end rot) on a tomato. Calcium (Ca) deficiency is a plant disorder that can be caused by insufficient level of biologically available calcium in the growing medium, but is more frequently a product of low transpiration of the whole plant or more commonly the affected tissue.

  3. 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 ...

    Other functions attributed to calcium are: the neutralization of organic acids; inhibition of some potassium-activated ions; and a role in nitrogen absorption. A notable feature of calcium-deficient plants is a defective root system. [14] Roots are usually affected before above-ground parts. [15] Blossom end rot is also a result of inadequate ...

  6. Liming (soil) - Wikipedia

    en.wikipedia.org/wiki/Liming_(soil)

    Liming is the application of calcium- (Ca) and magnesium (Mg)-rich materials in various forms, including marl, chalk, limestone, burnt lime or hydrated lime to soil. [1] In acid soils, these materials react as a base and neutralize soil acidity.

  7. Calcicole - Wikipedia

    en.wikipedia.org/wiki/Calcicole

    A calcicole, calciphyte or calciphile is a plant that thrives in lime rich soil. [1] [2] The word is derived from the Latin 'to dwell on chalk'.Under acidic conditions, aluminium becomes more soluble and phosphate less.

  8. Agricultural lime - Wikipedia

    en.wikipedia.org/wiki/Agricultural_lime

    it provides a source of calcium for plants; it improves water penetration for acidic soils; it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on acid soils. [2] Other forms of lime have common applications in agriculture and gardening, including dolomitic lime and hydrated lime.

  9. Lime sulfur - Wikipedia

    en.wikipedia.org/wiki/Lime_sulfur

    Bonsai enthusiasts use undiluted lime sulfur to bleach, sterilize, and preserve deadwood on bonsai trees while giving an aged look. [5] Rather than spraying the entire tree, as with the pesticidal usage, lime sulfur is painted directly onto the exposed deadwood, and is often colored with a small amount of dark paint to make it look more natural.
