Several factors affect soil fertility, including:
- Soil pH: The pH level of the soil can affect the availability of nutrients to plants.
- Soil texture: The texture of the soil, determined by the proportions of sand, silt, and clay, can affect its ability to hold nutrients and water.
- Organic matter: Organic matter contributes to soil fertility by providing nutrients and improving soil structure.
