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 to provide adequate levels of phosphorus and potassium for good plant growth without adverse effects on the environment.
Regular Tests (with recommendations)
- Regular Series (phosphorus, potassium, pH and lime requirement, organic matter (%) and estimated texture class)
- Soluble Salts (from excess fertilizer or road salt)
Professional Tests (no recommendations)
- Micronutrient Series (zinc, copper, iron, manganese)
- Calcium and Magnesium
- Total Organic Matter (%)
