Manganese Deficiency: How to Identify & Treat Fast

Manganese deficiency is a nutritional disorder that causes interveinal chlorosis in younger leaves, creating a distinctive chequered pattern. Unlike magnesium deficiency which affects older leaves first, manganese deficiency appears in new growth at the top of the plant. It is most common in poorly drained soils, high organic matter conditions, and soils with pH above 6.5.

🔍 What Are the Symptoms of Manganese Deficiency?

TLDR: Manganese Deficiency presents 7 main symptoms. Early identification is crucial for effective treatment.

Main Symptoms

  • ! Interveinal chlorosis with smallest veins remaining green (chequered pattern)
  • ! Yellowing starts in younger leaves at top of plant
  • ! Brown spots may appear on leaf surfaces
  • ! Severely affected leaves turn brown and wither
  • ! Leaf curling in severe cases
  • ! Stunted growth
  • ! Small necrotic spots if deficiency persists

What Causes Manganese Deficiency in Plants?

  • Soil pH above 6.5 (alkaline conditions)
  • Poorly drained or waterlogged soils
  • High organic matter levels
  • Coarse soil texture
  • Cold soil temperatures
  • Excessive phosphorus or iron in soil
  • Sandy soils with low manganese content
