Micronutrient deficiency is defined as the sustained insufficient supply of vitamins and minerals needed for growth and development, as well as to maintain optimal health. Since some of these compounds are considered essentials (we need to obtain them from the diet), micronutrient deficiencies are often the result of an inadequate intake.
Boron deficiency will often result in bud dieback. Chloride is necessary for osmosis and ionic balance; it also plays a role in photosynthesis. Copper, iron, manganese, molybdenum, and zinc are cofactors essential for the functioning of many enzymes. [19] For plants, deficiency in these elements often results in inefficient production of ...
Micronutrients are nutrients such as vitamins and minerals required by organisms in varying quantities throughout life to orchestrate a range of physiological functions to maintain health. [1] [2] The following is a list of micronutrients used by various living organisms. For human-specific nutrients, see Mineral (nutrient).
Visual symptoms distinctive enough to be useful in identifying a deficiency are rare. Most deficiencies are multiple and moderate. However, while a deficiency is seldom that of a single nutrient, nitrogen is commonly the nutrient in shortest supply. Chlorosis of foliage is not always due to mineral nutrient deficiency. Solarization can produce ...
In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, but most are not. [ 1 ] [ 2 ] [ 3 ] Minerals are one of the four groups of essential nutrients; the others are vitamins , essential fatty acids , and essential amino acids . [ 4 ]
See Vitamin, Mineral (nutrient), Protein (nutrient) An inadequate amount of a nutrient is a deficiency. Deficiencies can be due to several causes, including an inadequacy in nutrient intake, called a dietary deficiency, or any of several conditions that interfere with the utilization of a nutrient within an organism. [1]
Nutrient deficiency may refer to: Malnutrition , a condition in animals that results from a diet deficient in calories and/or essential nutrients Micronutrient deficiency , a lack of one or more of the micronutrients required for plant or animal health
Selenium deficiency as defined by low (<60% of normal) selenoenzyme activity levels in brain and endocrine tissues only occurs when a low selenium status is linked with an additional stress, such as high exposures to mercury [27] or as a result of increased oxidant stress due to vitamin E deficiency.
