  • Macronutrients
    Nutrient elements that are absorbed by plants in large amounts
  • Micronutrient elements 

    A type of nutrient elements that absorbs by the plant in smaller amount
  • Structural elements
    Carbon, Hydrogen and Oxygen is a type of nutrient elements that comes from water and air. What do you call this type of nutrient elements?
  • Manganese
    Which of the following is a micronutrient?
  • NO2-
    Which of the following is a symbol of Ammonium?
  • Molybdenum
    The micronutrient element that is absorb by the plant in least amount
  • Nitrogen
    Plant nutrient that encourage vegetative growth of plants
  • Phosphorus
    Plant nutrient that is required for energy transfer of ATP and ADP
  • Magnesium
    A micronutrient that is a central component of chlorophyll
  • Sulfur
    Nutrient that is essential component of amino acid Methionine, Cysteine and Cystine
  • Sulfur
    Nutrient that is a constituent of coenzyme A, Biotin, Thiamine and Glutathione
  • Potassium
    A macronutrient that is not a component of any organic molecule
  • Molybdenum
    Micronutrient that is involve in nitrogen fixation
  • Zinc
    Micronutrient which is involve in the synthesis of auxin
  • Iron
    Micronutrient which is involve in chlorophyll synthesis
  • Calcium
    Nutrient which is a constituent of cell wall
  • Boron
    Micronutrient that is important in the translocation of sugars
  • Potassium
    Nutrient that can increase pest and disease resistant
  • Mobile nutrients
    Deficiency of these nutrients mostly on macronutrients can be seen in older leaves or lower part
  • Immobile nutrients
    Deficiency of these nutrients mostly on micronutrients can be seen on younger leaves or upper part
  • Micronutrient
    Needed by the plants relatively in low amount
  • Phosphorus
    Deficiency of this micronutrient can make plants become stunted and shows purple coloration on their leaves
  • Potassium
    Deficiency of this micronutrient shows scorching or burning on their leaf margins
  • Potassium
    When this nutrient is excessive, it leads to nitrogen deficiency
  • Calcium
    Deficiency that cause blossom end rot disease in tomato
  • Manganese
    Plant shows interveinal chlorosis on younger leaves
  • Iron
    Micronutrient needed in hemoglobin formation
  • Iron
    Deficiency that cause chlorosis on younger leaves
  • Calcium
    A micronutrient that is part of middle lamella and deficient in acid upland soils
  • Nitrogen
    A macronutrient that is a component of protein and chlorophyll and is most limiting element in crop production except for legumes
  • Calcium
    Considered as one of the lime nutrients
  • Nitrogen cycle

    It is a biogeochemical process through which nitrogen is converted into many forms and it involves several processes such as Nitrogen fixation, Nitrification, Denitrification and Volatilization
  • Leaching
    A downward movement of water with mineral nutrients and sometimes cause of soil acidity
  • Mineralization
    A process where organic N is converted into inorganic N and renders available for plant use
  • Immobilization
    A process where inorganic N is converted into organic N and renders unavailable for plant use
  • Nitrite
    First product of Nitrification
  • Infiltration
    Downward entry of water
  • Percolation
    Downward movement of water
  • NH4+

    Symbol of Nitrite
  • Nitrate
    Final product of Nitrification
