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 .
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).
Micronutrients are essential dietary elements required by organisms in varying quantities to regulate physiological functions of cells and organs. [1] [2] Micronutrients support the health of organisms throughout life. [3] [4] [5] In varying amounts supplied through the diet, micronutrients include such compounds as vitamins and dietary minerals.
Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [ 2 ] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.
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 ...
Micronutrients are essential dietary elements required in varying quantities throughout life to serve metabolic and physiological functions. [6] [7] 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 ...
The carbohydrates produced are stored in or used by the plant. Most plants obtain nutrients through inorganic substances absorbed from the soil or the atmosphere. Carbon, hydrogen, oxygen, nitrogen, and sulfur are essential nutrients that make up organic material in a plant and allow enzymic processes.
They are not considered nutrients, as they are not used for growth, survival or reproduction, nor do they provide dietary energy. Therefore, they do not have recommended daily intake levels, as exist for vitamins, minerals, and fiber.
