Lawn/Garden and Professional Turf Tests

The tests provided by the University of Minnesota Soil Testing Laboratory are for the purpose of evaluating the soil fertility and soil pH level and/or problems due to excessive salts or fertilizer materials. Based on test results and the type of plants to be grown, you will be sent the appropriate fertilizer recommendation that will provide adequate levels of phosporus and potassium necessary for good plant growth without adverse effects on the environment.
