Potatoes - Chlorosis

Symptoms
Young leaves become uniformly yellowgreen.

Reasons
Molybdenum deficiency Young plants can show deficiency symptoms if seed potatoes were grown on soils with low Mo content. Yellowing of leaf blades is similar to nitrogen or sulfur deficiency.

Molybdenum deficiency made worse by

  • Acid soils
  • Low pH
  • Low levels of soil organic matter

Molybdenum is important for

  • Nitrogen metabolism, pigment and chlorophyll synthesis
  • Beneficial for growth and yield
