  • Arnon and Stout

    who proposed the term essential elements, and created the criteria for the essential elements

  • oral

    4 criteria for essential elements

  • Carbon, Hydrogen, Oxygen

    are considered to be non-mineral nutrients

  • derived from air and water rather than the soil

    why are non-mineral nutrients considered non mineral

  • Beet root, Atriplex vesicaria

    sodium is essential to what specific crops

  • Na, Si, Co

    beneficial elements

  • Beneficial elements

    Elements which either stimulate growth but are not essential or which are essential only for certain plant species, or under specific conditions, are usually defined

  • Silicon

    an element that decreases incidence to fungal infections and preventing Fe and Mn toxicity.

  • Cobalt

    an element that is essential for N-fixing organisms, irrespective of whether they are in the free-living or symbiotic form.

  • Cobalt

    It is the metal component of vitamin B12

  • Silica

    ome crops will respond to this element in highly weathered soils.

  • >100 mg/kg

    Macronutrients are elements that are used in relatively large amounts

  • <100 mg/kg

    Micronutrients are elements that are used in relatively small amounts

  • Nitrogen, Phosphorus, Potassium

    primary nutrients

  • Calcium, Magnesium, Sulphur

    secondary nutrients

  • CO2

    carbon ionic form

  • O2, CO2

    oxygen ionic form

  • H2O

    hyrogen ionic form

  • Ca2+

    calcium ionic form

  • K+

    potassium ionic form

  • H2PO4- , HPO4 -2

    phosphorus ionic form

  • Cl-

    chlorine ionic form

  • Mg 2+

    Magnesium

  • SO4 -2

    sulfur ionic form

  • Fe 2+, Fe 3+

    iron ionic form

  • Mn 2+

    manganese ionic form

  • Zn 2+

    zinc ionic form

  • h3Bo3, H2BO3-

    boron ionic form

  • Cu 2+

    copper ionic form

  • Ni 2+

    nickel ionic form

  • MoO4 -2

    Molybdenum ionic form

  • Group 1 (CHONS)

    Forms the organic components of plants Plants assimilate these nutrients via biochemical reactions involving oxidation and reduction

  • Group 2 (PB)

    Esterification with native plant alcohol. Phosphate esters are involved in energy transfer

  • Group 3 (K, Mg, Ca, Mn, Cl)

    Nonspecific functions, involved in establishing osmotic potential. Ca is a component of plant structural parts.

  • Group 4 (Fe, Cu)

    Present predominantly in a chelated form in prosthetic group, enable electron transport by valency change

  • mobile nutrientss

    old leaves are having symptoms, what deficiency

  • nitrogen, phosphate, potassium, magnesium, chlorine, zinc and molybdenum.

    mobile nutrients

  • Calcium, sulfur, iron, boron and copper

    immobile nutrients

  • Carbon

    constituent of carbohydrates; necessary for photosynthesis

  • Hydrogen

    maintains osmotic balance; important in numerous biochemical reactions; constituent of carbohydrates

  • Oxygen

    constituent of carbohydrates, necessary for respiration

  • Nitrogen

    constituent of proteins, chlorophyll and nucleic acids

  • Phosphorus

    Constituent of many proteins, coenzymes, nucleic acids and metabolic substrates; important in energy transfer

  • Potassium

    nvolved with photosynthesis, carbohydrate translocation, protein synthesis, etc.

  • Calcium

    A component of cell walls; plays a role in the structure and permeability of membranes

  • Magnesium

    enzyme activator, component of chlorophyll

  • sulfur

    important component of plant proteins

  • Boron

    believed to be important in sugar translocation and carbohydrate metabolism

  • Chlorine

    involved with oxygen production in photosynthesis

  • Copper

    catalyst for respiration; a component of various enzymes Component of cytochromes and nitrogenase

  • Iron

    involved with chlorophyll synthesis and in enzymes for electron transfer

  • Mangen

    controls several oxidation-reduction systems and photosynthesis

  • Molybdenum

    involved with nitrogen fixation and transforming nitrate to ammonium

  • Nickel

    necessary for proper functioning of the enzyme, urease, and found to be necessary in seed germination

  • Zinc

    necessary for proper functioning of the enzyme, urease, and found to be necessary in seed germination

  • Leaves

    At early growth stages, the highest concentration of nutrients are found in

  • leaves

    during near harvest, , the lowest concentration of nutrients are found in
