Lombtrágyázás

Lombtrágyázás, also known as foliar feeding or foliar fertilization, is a method of delivering nutrients to plants directly through their leaves. This technique involves spraying a liquid fertilizer solution onto the foliage, which is then absorbed by the plant's stomata, tiny pores on the leaf surface. Unlike soil fertilization, where nutrients must be absorbed by the roots and then transported throughout the plant, foliar feeding allows for a more rapid uptake of essential elements. This can be particularly beneficial when plants are experiencing stress, nutrient deficiencies, or when soil conditions hinder root absorption, such as in cold or waterlogged soils.

The effectiveness of lombtrágyázás depends on several factors. The formulation of the fertilizer is crucial; nutrients must be in a readily available and soluble form. The concentration of the solution also needs to be carefully controlled to avoid leaf burn. Application timing is important, with early morning or late evening being optimal times to minimize evaporation and maximize absorption when stomata are open. While lombtrágyázás can quickly address micronutrient deficiencies or provide a temporary boost, it is generally not a substitute for a comprehensive soil fertilization program, as it cannot supply the large quantities of macronutrients required for overall plant growth. It is often used as a complementary practice to soil-based nutrient management.
