Pelletized vs. Fast-Acting Lime

Q: I followed your recommendation to get my lawn soil tested. The results say I need to add 90 pounds of lime per 1,000 square feet. Is there a difference in pelletized lime and fast-acting lime?

A: University of Georgia soil scientist Dr. David Kissel says that pelletized lime is made by granulating finely ground limestone. Fast-acting lime is limestone that has been ground to be super fine, so it dissolves in the soil faster. However, university soil test results are based on the homeowner using coarse agricultural lime which has some particles that react slowly and some so large that they don’t react at all. This means you can use less pelletized or fast-acting lime than the soil test recommends. Instead of 90 pounds per 1000 square feet, 60 to 65 pounds of the finely ground lime should be sufficient. Retest in two years.
