As a rule of thumb, a 6.0-6.2 pH is best for growing vegetables. Usually 4 to 8 pounds of lime will be required for each 100 square feet of garden. However, the exact rate will vary, depending on the soil type, fertilization practices and previous liming history. A number of liming materials are available. The most common materials used in Georgia are calcitic and dolomitic limestone.
Calcitic limestone is composed mainly of calcium carbonates.
It supplies calcium as well as raising the pH. Dolomitic limestone sold in Georgia contains more than 6 percent elemental magnesium, in addition to calcium. Since Georgia soils are often deficient in magnesium, dolomitic limestone is usually recommended. There are some basic things we need to do to help ensure the success of our garden. Among the most basic are soil testing and applying lime when needed. Grow that beautiful garden and reap a bountiful harvest.
