You can have a pH of 7.0 and still have a calcium deficiency, you can have a pH of 8 or 9 and still have a calcium deficency. Calcium, magnesium, sodium and potassium all will raise the soil ph and calcium has the least effect of those 4 cation's. Doing a Ph test only tells you what your ph is, not how to correct it. If your soil pH is high because of potassium and sodium, you need lime to raise the calcium levels and help leach out the high sodium and potassium. If your soil ph is high because of to much magnesium, you need calcium and sulfur to lower the magnesium levels. A pH meter doesnot tell you whether you need to lime or not. Like Norm al says, it just makes you, and the home owner, feel warm and fuzzy.
