Lime Application
Estimate agricultural lime needed to raise soil pH.
About Lime Application
The pH gain needed is scaled by a typical rule of thumb and corrected for the product's neutralization strength. Lime counteracts acid soil that locks up nutrients, so an accurate rate improves what the fertilizer section can do.
Formula
Lime Application
Lime = pH rise x 50 / efficiency rating x 100
- efficiency
- Calcium carbonate equivalent of the lime product
Worked example

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Lime Application calculated?
Lime = pH rise x 50 / efficiency rating x 100 The pH gain needed is scaled by a typical rule of thumb and corrected for the product's neutralization strength.
Why does Lime Application matter?
Lime counteracts acid soil that locks up nutrients, so an accurate rate improves what the fertilizer section can do.
What values do I need to enter?
This calculator takes 4 inputs: Current pH, Target pH, Lime efficiency, Area. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
