Micronutrients
Micronutrients are plant nutrients essential for optimum plant growth, but required in small amounts. Most complete fertilizers contain 6 micronutrients, and the percentage of each is critical to prevent toxicities and/or deficiencies. These include: 1: Boron (B) – Aids in the differentiation of plant cells, and also regulates the metabolism of carbohydrates. 2: Copper {Cu) – Activates several essential enzyme systems in plants. 3: Iron (Fe) – Required for the formation of chlorophyll, and also controls the synthesis of indoleacetic acid, a plant growth regulator. 4: Manganese (Mn) – Assists iron in chlorophyll formation. High levels of Mn may induce Fe deficiency. This symptom is sometimes called Mn toxicity. 5: Zinc (Zn) – An essential component of several enzyme systems. Like Fe, it also controls the synthesis of indoleacetic acid. 6: Molybdenum (Mo) – Required by plants for utilization of...
