Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
If soil iron concentration is high, in spite of this it can become unavailable for absorption if soil pH is higher than 6.5. [1] Excess of elements such as manganese in the soil can interfere with plant iron uptake triggering iron deficiency. [2] Iron is needed to produce chlorophyll, hence its deficiency causes chlorosis.
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 ...
Dietary minerals, such as potassium, sodium, and iron, are elements native to Earth, and cannot be synthesized. They are required in the diet in microgram or milligram amounts. As plants obtain minerals from the soil, dietary minerals derive directly from plants consumed or indirectly from edible animal sources. [8]
Air plants are epiphytes, meaning they anchor to a host plant by their roots. They do not need soil to grow, absorbing moisture and nutrients through little scale-like structures, called trichomes ...
Starting at age 14, females need more iron than males due to menstruation. Women ages 19 to 50 require 18 mg of iron daily, while men in this age range only need 8 mg. During pregnancy, this need ...
On the other hand, nonheme iron is found in plant foods like beans, lentils and spinach. While this form of iron is also valuable, it is generally less easily absorbed by the body than heme iron.
The artificial solution described by Dennis Hoagland in 1933, [1] known as Hoagland solution (0), has been modified several times, mainly to add ferric chelates to keep iron effectively in solution, [6] and to optimize the composition and concentration of other trace elements, some of which are not generally credited with a function in plant nutrition.
