    Question

    Which of the following statements is/are true?

    Statement A: Organic matter in the soil improves soil fertility and nutrient availability. Statement B: Sandy soil has a high water-holding capacity. Statement C: Soil pH does not affect nutrient availability to plants. In the light of these statements, choose the correct answer from the options given below:
    A Only A is correct. Correct Answer Incorrect Answer
    B Only B is correct. Correct Answer Incorrect Answer
    C Only C is correct. Correct Answer Incorrect Answer
    D A and B are correct. Correct Answer Incorrect Answer

    Solution

    Statement A: Organic matter in the soil improves soil fertility and nutrient availability. This statement is true. It enhances the soil's ability to retain moisture, improves soil structure, promotes microbial activity, and increases nutrient availability to plants.  Statement B: Sandy soil having a high water-holding capacity is incorrect. Sandy soil typically has larger particles, resulting in larger pore spaces between them. These larger pores allow water to drain quickly through the soil, leading to poor water retention and limited water availability for plants.  Statement C: Soil pH affecting nutrient availability to plants is true. Soil pH significantly influences the solubility and availability of nutrients to plants. Different nutrients have varying solubility across different pH levels.
