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

Fossil fuels used for machinery are an example of a non-renewable resource in agriculture because they are derived from ancient organic materials that have undergone geological processes over millions of years. Once extracted and consumed, these resources cannot be replenished within a human timeframe.

In agricultural practices, fossil fuels are essential for powering machinery, transporting goods, and producing inputs such as fertilizers. Their finite nature makes reliance on fossil fuels a significant concern in sustainable agriculture.

In contrast, water used for irrigation is a renewable resource as it can be cycled through precipitation and managed through sustainable practices. Fertile topsoil, while not limitless, can be replenished with proper soil management techniques. Animal manure is also renewable, as it can be consistently produced by livestock and used to enhance soil fertility.
