Plant Nutrition

Plant nutrition is the study of the chemical elements that are necessary for plant growth. There are several principles that apply to plant nutrition. Some elements are directly involved in plant metabolism. However, this principle does not account for the so-called beneficial elements, whose presence, while not required, has clear positive effects on plant growth.

A nutrient that is able to limit plant growth according to Liebig's law of the minimum, is considered an essential plant nutrient if the plant cannot complete its full life cycle without it. There are 17 essential plant nutrients.

Macronutrients:

  • N = Nitrogen
  • P = Phosphorus
  • K = Potassium
  • Ca = Calcium
  • Mg = Magnesium
  • S = Sulfur
  • Si = Silicon

Micronutrients (trace levels) include:

  • Cl = Chlorine
  • Fe = Iron
  • B = Boron
  • Mn = Manganese
  • Na = Sodium
  • Zn = Zinc
  • Cu = Copper
  • Ni= Nickel
  • Mo = Molybdenum

Famous quotes containing the words plant and/or nutrition:

    If church prelates, past or present, had even an inkling of physiology they’d realise that what they term this inner ugliness creates and nourishes the hearing ear, the seeing eye, the active mind, and energetic body of man and woman, in the same way that dirt and dung at the roots give the plant its delicate leaves and the full-blown rose.
    Sean O’Casey (1884–1964)

    Men have their own questions, and they differ from those of mothers. New mothers are more interested in nutrition and vulnerability to illness while fathers tend to ask about when they can take their babies out of the house or how much sleep babies really need.
    Kyle D. Pruett (20th century)
