Foliar feeding
A technique of applying fertilizers directly to the leaves of plants through liquid sprays for rapid nutrient absorption.
Также говорят: foliar application, leaf feeding, foliar fertilization
Foliar feeding allows plants to absorb essential nutrients quickly through their stomata, bypassing the soil. This is particularly effective during periods of environmental stress, such as drought or root zone problems, where nutrient uptake through the roots is significantly restricted.
The best time to apply is during the plant's peak growth stages, such as flowering or fruit development. It is crucial to spray during cooler parts of the day, such as early morning or late afternoon, to ensure maximum absorption and prevent the liquid from drying too quickly on the leaf surface.
Common mistakes: using excessively high concentrations that cause leaf burn and improper mixing of incompatible chemicals in the tank. Growers should also avoid spraying during high winds or shortly before rainfall, as these conditions significantly reduce the efficiency of the application.
