Soil is made up of several main components, which include:
- Minerals - These are the inorganic particles that come from rocks and are a fundamental part of soil.
- Water - Essential for plant growth and soil health, water is found in the spaces between soil particles.
- Air (Oxygen) - Soil also contains air, which is crucial for the respiration of roots and soil microorganisms.
On the other hand, fertilizer is not considered a natural component of soil. Instead, it is a supplement that is added to soil to provide essential nutrients for plants, but it is not an inherent part of the soil itself.
So, to summarize, among the options you provided, fertilizer is not a component of soil.
