Rombiquel® Hierro SL

EU fertiliser.
Complexed iron deficiency corrector

Rombiquel® Hierro SL It is a liquid corrector complement to fertilization programs that prevents and corrects iron deficiencies. Rombiquel® Hierro SL is complexed with lignosulfonates, thus ensuring faster and more efficient absorption. In addition, the formulation is improved with the CITO+ complex manufactured exclusively by PLYMAG and providing the plant with an extra supply of energy.
Iron is essential for plants since:

  • Optimizes the synthesis of chlorophyll, avoiding chlorosis.
  • Participates in the structure of the chloroplasts responsible for carrying out photosynthesis.
  • Increases the synthesis of enzymes and metabolic processes without which plants cannot carry out their life cycle.
