One of the primary reasons to test your soil is to determine its nutrient content. Plants require various nutrients, including nitrogen, phosphorus, and potassium, to grow. Testing will help you understand whether these nutrients are abundant, deficient, or imbalanced.
2. pH Levels
The pH of your soil dictates the availability of nutrients to plants. Most plants thrive in soil with a pH of 6.0 to 7.5. A soil test can alert you to any pH imbalances, allowing you to amend the soil accordingly.
3. Soil Texture
Understanding the texture of your soil—whether it’s sandy, silty, clayey, or a combination—can help you choose the right plants for your garden and determine the appropriate watering and fertilization methods.
4. Contaminants and Safety
In urban areas or places with a history of industrial activity, soil may contain contaminants such as lead or pesticides. Testing can help identify these hazards and safeguard your health and that of your family.
