The pH of the soil tells you how acid or alkaline the soil is on a scale of 0 to 14. Neutral pH is 7.0, higher numbers are termed alkaline and lower numbers are termed acid. Most plants prefer a pH between 6.0 and 7.0 but there are exceptions. Some plants demand acid soil and a few like theirs alkaline. Soils in Minnesota tend to be alkaline.
Nutritional levels are an important part of the results.
Results should be given for phosphorus and potassium levels, but because nitrogen levels can vary drastically within a sample and from day to day, nitrogen isn't usually reported. Additional tests can be run on your soil sample if you suspect a specific problem such as lead in the soil or excessive salts. Some commercial labs automatically include results for several other elements such as calcium, magnesium, sulfur, sodium or others. How to Use the Results Soil test results are usually accompanied by recommendations customized to your intended use. Here is where the whole idea of testing your soil runs into difficulty for the homeowner.
