Rombiquel® Calcio SL

Complexed calcium deficiency corrector.

Rombiquel® Calcio SL is a calcium deficiency corrector complexed with lignosulfonates, thus ensuring faster and more efficient absorption. The formulation is enhanced with the CITO+ complex manufactured exclusively by PLYMAG and providing the plant with an extra supply of energy.

Calcium is essential for plants since:

  • Is an essential part of the cell wall, providing greater structural resistance.
  • Improves the texture of the fruit’s skin, increasing its post-harvest life.
  • Activates secretion processes necessary for the development of root hairs.
  • Activates pollen tube formation, improving flowering.
