The soil I purchased has too much calcium, 5466 ppm. How can I reduce the level of calcium?
Calcium in Soil

Too much calcium (or too high a pH) can tie up all other nutrients, especially magnesium, potassium, boron, zinc and copper. To lower the calcium level in your soil, you'll basically have to lower its pH. The best way to do this is too add granular sulfur to the soil. About 1 pound of sulfur per fifty feet will lower the pH 1 point. This will need to be worked or tilled into the soil. Other things you can try to lower the pH levels in your soil include adding sphagnum peat or diluted vinegar.
