USGA Summary Points:Current soil test methods may not be appropriate for sand-based systems. More work is needed on the Basic Cation Exchange Ratio (BCSR) soil test method for turfgrass areas. The impact of calcium to magnesium (Ca/Mg) ratios on turfgrass performance needs further study. Multiple tissue and soil samples were collected from seven different areas and analyzed using five different soil testing techniques to measure exchangeable basic cations. These methods include NH4Cl Mehlich III, Saturated Paste, NH4OAc pH 8.2, and NH4OAc pH 7.0 Preliminary results indicate that the NH4OAc pH 7.0 technique produced samples with an average of 30% and 10% more Ca than samples tested with the NH4OAc pH 8.2 method and the Mehclich III method, respectively.
