Which of the following is an organic fertilizer source?

• A. Ammonium sulfate
• B. Bone meal
• C. Synthetic urea
• D. Calcium nitrate

Answer: (B)

Bone meal is considered an organic fertilizer source because it is derived from the ground-up bones of animals, which provides essential nutrients such as phosphorus and calcium to plants. As an organic amendment, bone meal not only supplies nutrients but also improves soil structure and biology by contributing to the organic matter content of the soil. In contrast, ammonium sulfate, synthetic urea, and calcium nitrate are classified as synthetic or inorganic fertilizers. These substances are manufactured through chemical processes and are not derived from living organisms. While they can effectively supply nutrients to plants, they do not offer the soil-enhancing benefits that organic fertilizers provide. Using organic sources like bone meal tends to contribute to a healthier ecosystem in the soil, promoting beneficial microorganisms and overall soil health.
