  2. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    The macronutrients are taken-up in larger quantities; hydrogen, oxygen, nitrogen and carbon contribute to over 95% of a plant's entire biomass on a dry matter weight basis. Micronutrients are present in plant tissue in quantities measured in parts per million, ranging from 0.1 [3] to 200 ppm, or less than 0.02% dry weight. [4]

  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 ...

  4. Micronutrient - Wikipedia

    en.wikipedia.org/wiki/Micronutrient

    [1] [2] By enabling these processes, micronutrients support the health of organisms throughout life. [3] [4] [5] For humans, vitamins and dietary minerals are the primary micronutrients. [3] [6] Human micronutrient requirements are in amounts generally less than 100 milligrams per day, whereas macronutrients are required in gram quantities ...

    As many know, healthy, nutrient-rich soil supports a productive vegetable garden. Nitrogen (N), phosphorus (P), and potassium (K) are the key macronutrients required by plants for their growth.

  6. Nutrient - Wikipedia

    en.wikipedia.org/wiki/Nutrient

    Calcium, sodium, potassium, magnesium, and chloride ions, along with phosphorus and sulfur, are listed with macronutrients because they are required in large quantities compared to micronutrients, i.e., vitamins and other minerals, the latter often described as trace or ultratrace minerals. [3] Macronutrients provide energy:

  7. Fertilizer - Wikipedia

    en.wikipedia.org/wiki/Fertilizer

    The macro-nutrients are consumed in larger quantities and are present in plant tissue in quantities from 0.15% to 6.0% on a dry matter (DM) (0% moisture) basis. Plants are made up of four main elements: hydrogen, oxygen, carbon, and nitrogen. Carbon, hydrogen, and oxygen are widely available respectively in carbon dioxide and in water.

  8. Micronutrient deficiency - Wikipedia

    en.wikipedia.org/wiki/Micronutrient_deficiency

    In plants a micronutrient deficiency (or trace mineral deficiency) is a physiological plant disorder which occurs when a micronutrient is deficient in the soil in which a plant grows. Micronutrients are distinguished from macronutrients (nitrogen, phosphorus, sulfur, potassium, calcium and magnesium) by the relatively low quantities needed by ...

  9. List of micronutrients - Wikipedia

    en.wikipedia.org/wiki/List_of_micronutrients

    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).
