Use a soil test to determine what deficiencies may exist in the soil. Soil is made up of a combination of sand, silt, clay, air, water and organic matter. Organic matter is the universal soil improver, helping the soil hold moisture and nutrients. Key results we look at are the soil pH, the ratio of calcium to magnesium and level of calcium and the the important Cation Exchange Capacity (CEC). The CEC is a measure of the soil’s ability to hold and exchange cations such as potassium, calcium and magnesium. Also important, the Percent Base Saturation (next to the CEC on the UMASS Soil Test Report) shows values for potassium (target 2 to 5%), magnesium (target 10 to 15%) and calcium (target 65 to 75%).
