What is a micro-nutrient?

A micro-nutrient refers to essential nutrients that plants require in very small quantities for their growth and development. These nutrients play critical roles in various physiological functions, including enzyme reactions and nutrient uptake processes. Despite being needed in minimal amounts, micro-nutrients such as iron, manganese, zinc, copper, molybdenum, and boron are crucial for the overall health of plants. Deficiencies in these micro-nutrients can lead to specific physiological disorders and can adversely affect plant growth, even if the primary macronutrients are present in sufficient quantities. This distinction is important for effective fertilization practices, as both macro and micro-nutrients contribute to plant health, but their required quantities differ significantly.
