FOLIAR FERTILIZERS

Once the solution is evenly distributed on the leaf surface, the elements therein contained enter inside the leaf either through the foliar veins (translaminar penetration) or under the cuticle layer (citotropic penetration) and from there they rapidly reach the plant’s conductive system which delivers them to the cells.
In this way the use of the nutritive elements is almost immediate, unlike traditional soil fertilization where they have to overcome other elements’ antagonism, unsuitable pH and environment and various other constraints.
For a correct foliar fertilization we recommend:
-          Applications should be done early in the morning or late in the evening to better exploit the high humidity and leaf turgor
-          Applications should be done with almost complete absence of wind, especially when atomizers are used
-          Make sure the crop is not stressed by drought conditions (it is recommended to irrigate the day before the application)
-          A solution with sub-acidic pH promotes foliar absorption being  optimal for foliar applications
-          The use of an adequate moisturizer or surfactant agent reduces the superficial tension of the nebulized drops, it improves the foliar fertilizer distribution and absorption, it increases the wet surface and it lowers the risk of leaf-burnings and darkening
-          Choose a water volume and application pressure suitable for each crop (use the correct nebulization volume to grant the plant’s full coverage)
-          Do not apply the product before a rainfall (or a drip irrigation) so that the fertilizer won’t be washed away.
