Micronutrient Deficiencies in Apples

Recognize the visual signs of micronutrient deficiencies in apples Macronutrients tend to get all of the attention when it comes to plant nutrition, while micronutrients are frequently overlooked. When left untreated, micronutrient deficiencies and toxicities can severely affect plant health. Plants send out warning signals in the form of visual symptoms when they are under stress.
