Abstract/Contents:"Sand-based putting greens have limited nutrient holding capacity. Therefore, understanding the nutritional status of the root-zone media is essential to proper turfgrass management. This research is focused on basic cation (calcium, magnesium, potassium, etc.) nutrition of sand-based greens. Specifically, we are looking at different soil testing techniques for measuring exchangeable basic cations and cation exchange capacity (CEC). This study's findings were: The presence of CaCO3 can greatly affect the results of various soil testing techniques. Of the procedures examined in this research, the NH4OAc pH 8.1 appears to be the best extractant for measuring exchangeable cations from calcareous sand samples. The NH4OAc pH 8.1 technique had the lowest rates of dissolution of CaCO3, but it still dissolved appreciable quantities of CaCO3. Therefore, calculating an ECEC by summation of exchangeable cations measured from any of the procedures evaluated in this research, including NH4OAc pH 8.1, is not advised for samples from calcareous sands and a double extraction technique should be used when extremely accurate tests are needed."
