Kelp Zn
Supports enzymatic processes and helps against abiotic stress.
Key Physiological Benefits:
Zinc Correction & Auxin Synthesis: Kelp Zn is a specialized liquid fertilizer combining pure *Ascophyllum nodosum* seaweed extract with water-soluble Zinc. Zinc is the key cofactor for auxin synthesis, directly driving leaf expansion, internode elongation, and early vegetative growth.
Enzymatic & Abiotic Stress Protection: The natural osmoprotectants (mannitol, alginic acid) and elicitors in the seaweed extract, combined with Zinc, promote crop enzymatic pathways, ensuring flowering, cuajado, and fruit development under thermal stress.
MDT Energy Booster: Metabolic biostimulation via MDT ensures rapid cell entry and translocation of Zinc to active growth centers.
Designed for maximum physiological response
Formulated with premium inputs to activate internal plant pathways and optimize harvest potential.
