Lime’s primary role is to alter soil ph and offset soil acidity, which can improve the availability of plant nutrients.
What Is Lime Used for in Soil?
Lime is used to increase the pH of soil, making it more alkaline.
This is often done to correct the soil pH after it has become too acidic from too much rain or from using too much fertilizer. Lime can also be used to raise the pH of soil that is too low for certain plants to grow.
