What is a primary benefit of foliar micronutrient fertilizer applications?

The primary benefit of foliar micronutrient fertilizer applications is that they quickly correct micronutrient deficiencies in plants. When plants exhibit symptoms of micronutrient deficiency, such as chlorosis, stunted growth, or poor fruit development, applying nutrients directly to the leaves allows for rapid absorption and can lead to immediate improvement in plant health. This method bypasses the soil, delivering nutrients directly to the plant tissues where they are needed most and can be especially effective when plants are experiencing stress or during critical growth stages.

Although other options suggest benefits like preventing future deficiencies and enhancing overall plant growth, these are not the immediate advantages of foliar applications. Foliar feeding is typically a short-term solution focused on alleviating existing deficiencies rather than providing long-term soil fertility or ensuring future nutrient availability.
