The best way to determine if your soil is supplying the required nutrients for healthy plant growth is to perform a soil test. An evaluation of soil fertility and pH level is an important first step in developing a plan or diagnosing problems in your lawn. A soil test is the basis for organic inputs in a natural management program and is strongly recommended before we can effectively transition any lawn to an organic lawn care program.
Your basic soil test will recognize the nutrients (NPK) available. It will also measure soil pH. A pH of 7 is neutral and grass likes pH of 6.5. Higher numbers indicate alkaline conditions and lower numbers indicate acidic conditions. Organic matter is also measured on this soil analysis report.
