Lime Calculator
Enter the lime rate from your soil test first. A generic rate based on pH is not verified, and a single-application cap is not verified either.
Result: lime
Enter an area greater than 0.
Follow the product label.
How Much Lime Do You Need?
This is a converter. It does not look at soil pH and it does not suggest a rate. Type the pounds per 1,000 square feet printed on your soil-test report, and the area of the lawn.
Pounds = area ÷ 1,000 × the soil-test rate
Sample report, not a recommendation: if the report said 40 pounds per 1,000 square feet and the lawn is 2,000 square feet, the converter returns 80 pounds. Forty is not a rate this site stands behind. A cap on one application is not verified. Follow the product label.
What This Lime Calculator Will Not Do
- It will not turn a pH number into pounds. That table is not verified.
- It will not cap the application. That cap is not verified.
- It will not pick a product. There are no purchase links and no prices.
Common Mistakes With the Lime Calculator
- Typing a pH of 5.8 into the rate field. The field wants pounds per 1,000 square feet from the report.
- Using the sample 40 as if this site recommended it.
- Skipping the label. The result is only the arithmetic from your report.
Lime Calculator FAQ
Does this calculator choose a lime rate from soil pH?
No. Enter the rate from your soil test. A generic lime rate is not verified. Follow the product label.
How are the pounds computed?
Your area in square feet, divided by 1,000, times the pounds per 1,000 square feet on your soil test.
Is a per-application cap listed?
No. That cap is not verified. Follow the product label.
