Identification

• Soil tests measure a variety of health factors, such as soil pH and macronutrient levels (potassium, phosphorus and nitrogen). More advanced tests may measure other factors, such as organic matter levels, active carbon levels, water capacity and surface compaction.
  
  

Benefits

• Soil tests allow gardeners to familiarize themselves with the makeup of their soils. If a test is taken before planting, gardeners can add soil amendments to improve their soil pH and nutrient content. Testing soil health may also save money on unnecessary fertilizers and other soil amendments.
  
  

Types

• Do-it-yourself soil test kits are available at most nurseries and garden centers. For more comprehensive test results, take a soil sample to your local university extension office. Once the test is complete, you will receive instructions about how you can adjust nutrient and pH levels in your soil.
