Plant nutrients are commonly split into two categories:
- Major elements (macronutrients) that are required in relatively large quantities by plants, and
- Trace elements (micronutrients) that are essential for plant growth, but are only required in small amounts.
All elements must be available in a form that is useable by the plant, and in balanced concentrations that allow optimum plant growth.
