Speedfol™ Ca SC

Speedfol™ Ca SC is a highly concentrated source of calcium to be used as a foliar spray to prevent and correct calcium deficiency imbalances. Its application will result in improved vegetative development and better fruit firmness and fruit quality (pre and post harvest).

Calcium has three main functions in the plant.
Calcium is essential for cell walls and plant structure. About 90% of the calcium is found in the cell walls. It acts as a cohesion factor that cement cells together and holds their structure in plant tissues. Without Ca, the new tissue development (cell division and extension) of roots and shoots is stopped. As a consequence the crop yield is badly affected.

Hide Technical Info
Speedfol™ Ca SC is a suspension concentrate formulation that contains a highly concentrated nutrient solution, which means that only a small quantity of product is needed to supply the desired amount of nutrients.

The built-in adjuvants favour a fast absorption of all nutrients in the formulation, reducing the risk of early wash-off by rainfall.

It does not contain chloride and heavy metals, thus minimising the risk of contamination, scorching or phytotoxicity.

Speedfol™ Ca SC conforms to the EPA, EUREPGAP and GAP norms for foliar plant nutrition.

  • It is the key element responsible for the firmness of fruits. Calcium delays senescence resulting in long lasting leaves capable to continue the photosynthesis process.
  • It maintains the integrity of cell membranes. This is important for the good functioning of uptake mechanisms as well as for preventing leakage of elements out of the cells.
  • Ca is also at the heart of plant defence mechanisms that help plants to detect and react against external stresses. Both roles in plant defence and on tissue firmness are important for resistance against pathogen attacks and decay during fruit storage.
  • One particularity of calcium is that it is almost exclusively transported with the transpiration stream along the xylem, which means it is mainly distributed from the roots up to the leaves, the main transpiring organs. It means that fruits that have a low transpiration rate are poorly supplied with calcium.
