The following elements are categorized as secondary nutrients: magnesium, calcium and sulfur. - [Micronutrients](https://cropnuts.com/nutrient_class/micronutrients/) - Micronutrients are nutrients that are required by plants and other living organisms in small amount. Not to say they are not important but required in small amount.
