Which is an example of a non-renewable resource in agriculture?

• A. Water
• B. Fertile soil
• C. Mineral fertilizers
• D. Sunlight

Answer: (C)

Mineral fertilizers are considered a non-renewable resource in agriculture because they are derived from finite mineral deposits that take millions of years to form. Once these resources are extracted and used, they cannot be replenished on a human timescale. This distinguishes them from renewable resources, which can be regenerated naturally over time. In contrast, water, while it can be a limited resource in certain contexts, is generally considered renewable through the water cycle. Fertile soil, although it can degrade with poor management, can be replenished through practices like crop rotation and organic amendments, making it mostly renewable under good management practices. Sunlight is an abundant and continuous resource, inherently renewable as it is always available for photosynthesis in the agricultural context. This understanding emphasizes the importance of managing non-renewable resources carefully to ensure sustainable agricultural practices.
