Foliar feeding refers to the practice of applying nutrients directly to the leaves of plants in the form of a liquid spray. While plants primarily obtain nutrients through their roots in hydroponics, foliar feeding can offer several benefits in certain situations. Here are some reasons why growers may choose to foliar feed:
Rapid Nutrient Absorption: Foliar feeding allows for direct nutrient absorption through the leaf surfaces, bypassing the root uptake process. This can be particularly beneficial when plants are experiencing nutrient deficiencies or when there are challenges with nutrient uptake through the roots. Foliar feeding provides a quick and efficient way to deliver nutrients directly to the plant tissues, resulting in faster nutrient availability.
Correcting Nutrient Deficiencies: If plants show signs of nutrient deficiencies, foliar feeding can provide an immediate solution by supplying the deficient nutrients directly to the affected leaves. This helps alleviate deficiencies more rapidly than waiting for root absorption. It can be especially useful for nutrients that are not easily taken up by roots under certain conditions, such as when the pH is imbalanced or root function is impaired.
