Nitrogen's Role in Plants

  • Nitrogen is always the nutrient in highest demand by plants, due to the greater content of nitrogen present on a dry weight basis in comparison to any other nutrient.
  • Nitrogen is a primary component of amino acids which are the building blocks of proteins. Thus, by adding nitrogen to soil the protein content in plants is increased.
  • Nitrogen is part of the chlorophyll molecule, and a part of numerous enzymes and coenzymes. Chlorophyll is responsible for photosynthesis, where sunlight is absorbed and stored in the plant as sugars and proteins.
  • Therefore, nitrogen is an integral part of photosynthesis.
  • Signs of nitrogen deficiency – reduced plant growth, yellowing of the leaf, early crop maturing.

Phosphorus’s Role in Plants

  • The most important role of phosphorus is the storage and transfer of energy that is generated through photosynthesis along with the metabolism of carbohydrates.
  • Phosphorus is an essential compound of Adenosine Triphosphate (ADP), the energising component driving plant development.
  • Phosphorus deficiency has a huge impact on plant growth and reproduction, reducing the plant processes noted below.
  • Processes aided by phosphorus:
    • Large root growth
    • Early formation of plant shoots
    • Improved stalk and stem strength in crops
    • Improved fruit, vegetable, and grain quality
    • Seed formation
    • Resistance to moisture and colder temperatures

Calcium's role in crops and pastures

  • Calcium is vital for both plant and animal growth
  • An essential part of the plant cell wall and membranes, aiding in plant structure and stability
  • Earthworm activity is increased by the presence of calcium in the soil profile, therefore natural soil aeration is also increased
  • Boosts soil microorganism activity, improving soil structure
  • Calcium deficiency affects fruit crop quality and growth, and limits biological activity
  • Calcium and magnesium work in synergy to promote stable soil structure
  • Involved in the signalling of the availability of other nutrients (e.g. potassium), through its secondary messenger characteristics
  • Assists in protecting the plant from biotic stresses
