Organic fertilizers differ from synthetic fertilizers because they are derived from what material?

Organic fertilizers differ from synthetic fertilizers because they are derived from what material?

• A. Water-soluble salts
• B. Mineral deposits
• C. Plant or animal material
• D. Synthetic chemical compounds

Answer: (C)

This item is about the origin of nutrients in fertilizers. Organic fertilizers come from natural plant or animal material, such as compost, manure, bone meal, or fish meal. Because they originate from decomposing organic matter, they feed the soil biome and release nutrients gradually as microbes break them down, often improving soil structure and long-term fertility. Inorganic options like water-soluble salts, mineral deposits, or synthetically manufactured compounds come from non-biological sources and are typically more immediately available and precisely formulated. So, plant or animal material best captures the defining difference.
