Soil Testing
Don’t guess Soil Test. Soil testing is a good idea when you are planting in
a new area, or if plants are not doing well. Soil testing is offered through
the Washtenaw County Extension/MSU Extension Office.
A soil test will determine the pH of soil, the current fertility of the soil, and
give recommendations for fertilizer applications. Note: this is not a test for
contamination of soils, diseases, or insects in the soil.
