Answer for ts seems with bagged lime that I will get additinal years of value.Will get the sams with this or is this an annual requirement.

PlotStart works immediately increasing pH levels starting the moment it is applied; whereas, lime can take months to begin to work. Shown to work up to 3X faster than ag lime. The residual affects of “bagged lime” in multiple year are comparable to a shorter amount of time with PlotStart. If soil tests reveal that you have a low pH then PlotStart will increase it faster than lime. Annual spraying of PlotStart is recommended if needed after a soil test.
