Foliar absorption occurs in two phases: Passive: the ions enter the plant through purely physical phenomena, such as simple diffusion, facilitated diffusion, ion exchange, etc. These cross the cuticle, the cell wall and the intercellular spaces, reaching the external surface of the plasmalemma. Its speed depends on the characteristics of the leaf and the environment, and may be reversible; Active: the element crosses the plasmalemma, reaching the cytoplasm and can accumulate in the vacuole or be transported to other parts of the plant, with energy expenditure. This is a slower but irreversible phase. ????
