How Do I Test Soil pH?
Actually we recommend a soil pH of 4.5 to 6.5.
For a small home planting you can use the MSU Extension, Soil Test Kit Self-Mailer (E3154).
It includes instructions on how to takes the soil sample and a bag for the soil to return to the MSU soils lab. The test results are returned to you by email and you can see recommendations on a website dedicated interpreting these soil test and fertilizer recommendations.
For larger commercial plantings you can buy soil test boxes at your county MSU Extension office and mail the samples to the soil test lab and they will return the results to you.
