VitaFer EXTRA Ca

Mineral fertiliser for the intervention and preventive supply of calcium, nitrogen and magnesium.

Density 1.4 kg/l

pH 6.0 – 7.0


Recommendations for use: 

– To correct calcium deficiencies in plants either intervening or preventively, especially during periods when its natural uptake by the root system is impaired. 

– To improve the quantity and quality of the yield and storability – better flavour, higher fruit firmness, better colouring. 

– To strengthen leaf and stem structure. 

– As a plant growth booster on acidified soils. 

– To provide protection against dry apical rot disease, which is caused by a deficiency of calcium in the plants  

– To stimulate the development of the root system by increasing the uptake of nutrients from the soil. Also as an aid against cabbage syphilis. 

The role of calcium in plants: 

  • Regulates enzyme activity in plant metabolic processes (growth, development, yield) 
  • Mitigates the effects of biotic and abiotic plant stresses 
  • Has a strong influence on plant cell structure and division 
  • Increases plant resistance to mechanical damage and damage caused by diseases and pests 
  • It promotes proper rooting of plants and influences the uptake of adequate amounts of water and nutrients from the soil. 

Calcium deficiencies result in:

  • Glassy patches on young leaves, fruit, and flowers
  • Necrosis on leaf edges
  • Dwarfing of flowers
  • Dry apical rot of plants
  • Subcutaneous bitter spot
  • Cracking of plums and cherries
  • Browning of the skin
  • Strawberry sponginess

Dosage and timing of application: 

Attention: The fertilizer must not be mixed with phosphate fertilizers.
