What does lye do for the ground?

Answer 1

Adds potassium and increases pH.

Answer 2

Lye can help improve soil quality by increasing pH levels, which can benefit certain plants that prefer more alkaline growing conditions. However, lye is caustic and can be harmful if not used properly, so it should be applied cautiously and in appropriate amounts under guidance. It is important to conduct a soil test before applying lye to ensure it is needed and to avoid over-treating the soil.
