Ag lime has fine, medium and large sized pieces in it, pelletized lime is powdered lime pressed into pellets.

Ag lime will last several years because of the different time it takes for each size pieces to break down and leach into the soil. Pelletized usually will last 3-4 months but is easier to handle and apply.

Different areas of Indiana have different soil PH. For optimum results do a soil test and that will tell you how much to add or not add. h.h.
