Question
Which of the following is not considered as a primary nutrient for plant?NitrogenOxygenPhosphorousPotassium
Solution
The nutrient that is not considered a primary nutrient for plants among the options given is Oxygen. The primary nutrients for plants are Nitrogen, Phosphorous, and Potassium. These are often referred to as the "N-P-K" ratio that you see on fertilizer packages, because they are the three primary nutrients needed in the largest amounts for plant growth. Oxygen, while essential for plant respiration, is not typically classified as a primary nutrient because it is a component of air and water, which plants generally have ample access to.
