Oasis Agri Prescription Blended Trace Elements Nutrients and Functions – Part 5: Manganese

MANGANESE (Mn)

Functions in Plants and Soil:

  • Photosynthesis:

Manganese is essential for energy production during photosynthesis; it is crucial for converting light energy into chemical energy.

  • Enzyme Activation:

Manganese activates various enzymes within a plant. Some of which are required for nutrient metabolism as well as some required for carbohydrate metabolism and starch production.

  • Plant Defence and Resistance:

Manganese is required for lignin production, which assists in resistance to cell wall damage. It also has an antioxidant function, which protects the plant from stress.

  • Plant Strength and Structure:

As a requirement of lignin production, manganese assists in strengthening of cell walls and ultimately provides strength and structure to the plant.

  • Promotes Growth:

Manganese influences cell division and elongation, which is fundamental for overall plant development.

Deficiency Symptoms in Plants:

Note: Deficiency symptoms can present differently depending on the crop species

Manganese is an immobile plant nutrient. Symptoms therefore can typically occur in the youngest leaves and growing points.

  • Primary Symptoms:
    • Interveinal chlorosis (yellowing of leaves between the veins).
    • Pale colouration.
    • Necrotic brown or grey spots/streaks.
    • Deformed curled leaves with a wavy appearance.
  • Secondary Symptoms:
    • Overall stunted growth.
    • Reduced yield due to impaired photosynthesis.
    • Abscission of developing leaves with reduced flowering and fruit formation.
    • Increased susceptibility to stress and disease.
  • Crop Specific:
    • Maize and Soya:
      • Interveinal chlorosis of the youngest leaves. Contrast between green veins and yellow interveinal areas is prominent.
    • Potatoes:
      • Small, black necrotic spots on the middle portion of leaves, the surrounding area is slightly less green than the leaf area towards the margins.
    • Cereals:
      • Pale green or yellow patches on the youngest leaves.
