The elements required to the soil in small amounts are called:

A. Micronutrients

Micronutrients are essential for plant growth, even though they are needed in much smaller quantities compared to macronutrients. They play various roles in plant physiology, but only a tiny amount is sufficient. Examples of micronutrients include boron, copper, iron, and zinc.

Here’s a breakdown of the other options:

• B. Macronutrients: These are elements required by plants in relatively large amounts. Examples include nitrogen, phosphorus, and potassium.
• C. Meganutrients: This term is not a standard scientific term used in soil science.
• D. Microscopic: Microscopic refers to the size of something being very small and needing a microscope to see. While some micronutrients may have microscopic particles, it doesn’t describe their function in the soil.
