Which of the following is not a function of sulphur?
Correct answer: D. Control of pH of soil
- A. Enlarged root system in plants
- B. Chlorophyll development in leaves
- C. Good yield of crops
- D. Control of pH of soil
Explanation
Sulfur can affect soil pH when it reacts with water to form sulfuric acid or sulfate ions, thereby influencing soil acidity. However, controlling soil pH is not considered a primary function of sulfur. Other factors, such as the presence of acidic or alkaline compounds, primarily influence soil pH. Therefore, option D is correct as sulfur's primary function is not to control soil pH.
