Answer for Do I need to reapply PlotStart every year to maintain PH level? How long does it maintain the PH?

PlotStart begins to break down the materials that help neutralize the soil instantly, it will continue to do so overtime and can last several years depending on the use of the calcium and pH of the soil to start. It’s residual so next year you would simply be supplementing and not starting from scratch like a liquid lime product. If your calcium and pH levels are low, then yes, you will likely need to supplement. If you are just trying to grow better food plots, a lower dose of PlotStart in an average soil in years after initial application will be more than enough to grow a great plot.
