The trouble with calcium

Published: Thursday, January 30, 2014 at 02:36 PM.

Materials commonly used for this purpose are agricultural limestone, hydrated lime and dolomite.  Dolomite contains calcium and another important element, magnesium.  If you just need to change the pH level for your soil, agricultural limestone is probably the best material to use.  However, many acid sandy soils in Florida re low in magnesium, so dolomite can be sued to raise the pH and supply magnesium at the same time.

As we said, the decision to use these materials should be based on soil test results.  The amount you need depends on the soil pH you have, the soil type and the amount of organic matter in the soil.

For more information on calcium contact the Gulf County Extension Service @ 639-3200 or visit our websitehttp://gulf.ifas.ufl.edu or www.http://edis.ifas.ufl.edu.
