Foliar amino acids: how plant absorption works

The science behind advanced foliar nutrition and the cellular impact of directly applying free amino acids.

Juma-Agro Technical TeamDr. Fernanda Costa

The use of foliar amino acids has grown rapidly in agricultural management. Unlike conventional fertilizers, free amino acids directly enter plant metabolic pathways without requiring extra energy expenditure.

Cuticular and stomatal uptake

Foliar-applied amino acids penetrate the plant through both the cuticle and stomatal openings. Due to their small molecular size, absorption occurs quickly and efficiently.

Once inside plant cells, they are targeted to the synthesis of specific proteins that help the plant withstand environmental stresses, herbicide phytotoxicity, and boost overall growth.

"By applying free foliar amino acids, we spare the plant metabolic energy, allowing it to express its maximum yield potential."
