Calcium deficiency

Constraint – Calcium

Plant use

  • Calcium is a macronutrient involved in the proper functioning of growing points and maintaining strong cell walls

  • Deficiency symptoms are rare because calcium is common in soil, and is a component of many fertiliser and soil amendment products

Symptoms

  • Seen first in youngest tissues

  • Plants may be limp/wilt, with stunted root systems

Damage

  • Soils low in calcium usually have associated adverse conditions, such as low pH and aluminium, iron, and manganese toxicities

  • These associated conditions can cause varying yield penalties

Management

A soil test to determine how deficient the soil is, and the application of an appropriate amount of lime, is usually sufficient to correct the deficiency.
