Abstract
Applying micronutrients via foliar sprays has become increasingly important in modern orchard management as it addresses nutrient deficiencies that are often difficult to correct with conventional soil applications. This review summarizes existing research on the efficacy, methods, and benefits of foliar micronutrient application in different orchard systems. Particular emphasis is placed on key micronutrients such as iron, zinc, manganese, copper, boron, molybdenum, and chlorine to emphasize their importance to tree physiology, fruit quality, and overall orchard yield. It also examines the obstacles and best practices related to foliar fertilization, taking into account the timing of application, concentration and environmental aspects. By bringing together evidence from recent studies, this paper aims to provide fruit growers and researchers with a comprehensive understanding of foliar micronutrient strategies to optimize orchard well-being and overall productivity.
