Testing soil every three years helps you accurately apply fertilizers to your lawn and garden and helps avoid over-use of nutrients. Michigan State University Extension says soil testing is an important diagnostic tool to evaluate nutrient imbalances and understand plant growth. Testing enables gardeners to adjust soil pH to the optimum range, allowing for nutrients to be more available for plant growth. Knowing the pH and the nutrients needed helps to avoid allowing contaminants to enter local surface and ground waters by over-application of phosphorous or nitrogen fertilizers. Identifying exactly which nutrients plants need for adequate growth are the basis of deciding how much lime and fertilizer are needed, which can help you save money.
