What is foliar fertilization?
Foliar fertilization is the method of achieving fertilization through trichomes, stomata, leaf wax layer (cuticle) or through the intake and supply of plant cells (endocytosis).
The method of fertilizing through the root has its deficiencies that the foliar method solves, such as:
Some benefits of applying foliar fertilization are rapid nutrient intake, low amount of energy needed for nutrient transport, non-mobile nutritional elements remain in the plant, high absorption and no risk of fixation in the soil.
We must mention some points against this method, the most important being: The risk of burns or damage to the leaves, low doses should be applied, limited intake of nutritional elements.
Chitosan enhances plant survival and yield in times of heat or cold stress and drought.
