Which one of the following nutrients is not available in fertilizers?
Which one of the following nutrients is not available in fertilizers?
- A. Nitrogen
- B. Phosphorus
- C. \) Iron
- D. Potassium
Step-by-step solution
Standard fertilizers primarily contain the macronutrients nitrogen (N), phosphorus (P), and potassium (K), which are listed as N-P-K on labels. Iron is a micronutrient that may be included in specialized fertilizers but is not a typical component of general-purpose fertilizers. Therefore, iron is the nutrient not commonly available in fertilizers.
