Importance of Calcium

Look at these blackberries treated with OMEX CalMax at 1L/acre.

CalMax is a high quality new generation foliar suspension fertilizer containing 22.5% calcium (CaO), 15% nitrogen (N), 3% magnesium (MgO) and a range of EDTA chelated trace elements.   The application of CalMax products ensures optimum quality and shelf life.

Importance of Calcium in fruits and vegetables:

  • Calcium is one of the main constitutes of cell walls in plants. When it is in short supply, the structure of the cells weaken resulting in various disorders.
  • Calcium is instrumental in protecting the plant from toxins and slows down the ageing process.
  • Calcium is not very mobile in the plant and during periods of rapid growth or stress, the supply of this element to low transpiring organs, like fruit or young leaves, can be impacted.
  • Deficiency symptoms can occur even when there are adequate levels present in the soil.
  • Calcium is only taken up by a very small fraction of new roots.  Anything that restricts root development will affect Ca uptake.
  • Stress periods are often attributable to hot, dry weather, drying winds or high humidity.
  • Excessive use of nitrogen or potassium fertilisers can inhibit calcium uptake from the soil.
  • There is evidence to show that calcium plays a major role in protecting plants against fungal attack by helping to provide a physical barrier.
