plant nutrients
Growth-promoting compounds
Plant nutrients are the chemical elements and compounds that plants absorb from soil, water, and air to grow and function.
The major nutrients—nitrogen, phosphorus, and potassium—appear prominently on fertilizer labels.
Secondary nutrients include calcium, magnesium, and sulfur.
Micronutrients like iron and zinc are needed in smaller amounts.
The soil test revealed a plant nutrient deficiency.
