Plant Nutrition Essentials

The total essential plant nutrients include seventeen different elements: carbon, oxygen, hydrogen, nitrogen, phosphorus, potassium, calcium, sulfur, magnesium, iron, boron, chlorine, manganese, zinc, copper, molybdenum, and nickel.

Plants absorb carbon, oxygen, and hydrogen from the air.

The study of plant nutrition is in accordance with Justus von Liebig’s law of the minimum.
