Apples - Shortening of internodes

Symptoms
Typical symptoms of zinc deficiency are "little leaf" and "rosetting", caused by short internodes.

Reasons
Severe zinc deficiency

Zinc deficiency made worse by

  • Organic soils
  • High pH soils
  • Soils rich in phosphorus
  • Soils receiving high phosphorus application
  • Cold wet conditions

Zinc is important for

  • Combats chlorisis and premature leaf fall
  • Improves resistance to cold weather and late frosts
  • Improves bud development
  • Improves flowering
  • Improves fruit set
  • Gives better skin finish
  • Reduces storage disorders
