Micronutrient Deficiencies of Trees

What are micronutrients?

Micronutrients are mineral elements that are essential for growth of plants, but they are only needed in very small quantities. Micronutrients include iron, manganese, zinc, copper, boron, silicon, and molybdenum. These are in contrast to macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur), which are required in much larger amounts and make up a larger proportion of the plant tissue.
