Soil pH Adjuster: How Much Lime Raises Your Soil pH?
Acidic soil locks away nutrients, and lime is the usual fix. This adjuster estimates how much you need for your area.
What is the Soil pH Adjuster?
Lime raises soil pH, but the amount depends on how far you need to move it and how much ground you cover. Enter current and target pH and the area, and this tool estimates the lime in kilograms. This is a rough garden estimate: a soil test gives a more exact recommendation.

Worked example
Raising pH from 5.5 to 6.5 over 10 square metres needs an estimated 3 kg of lime.
How much lime raises pH from 5.5 to 6.5 over 10 square metres?
The estimate is 1.0 pH point times 10 square metres times 0.3 kg, giving 3 kg of lime, as a rough guide only.
