Vitalem Forte

VITALEM FORTE is a liquid formulation with high concentrations of free L-amino acids derived from an enzymatic hydrolysis of vegetal proteins, a process which is carefully controlled to keep the substances biological activity.

Amino acids of VITALEM FORTE play an essential role in the maintenance of the hydric equilibrium of plants, especially during adverse climatic conditions. Proline influences pollen fecundity, while others like methionine, arginine and lysine promote polyamides synthesis that regulate basic physiologic processes like germination, flower senescence or fruit ripening.

Application of VITALEM FORTE in irrigation systems provides essential metabolites, which are easily absorbed by the root systems, and increases soil fertility by stimulating microbial activity.

VITALEM FORTE can be used as a powerful tool to reactivate plant growth and metabolism altered by adverse physiologic events or abiotic stress.
