SOIL VALUE INTERPRETER

Make sense of a soil number.

Enter linear extensibility from a soil report. See the screening band, the exact boundaries and what the number cannot tell you.

REPORT VALUE, NOT A LOCATION CHECK

What does your report say?

Use LE/LEP, not clay percentage or plasticity index. NRCS valid LEP entries are 0–30%. Your input is interpreted on this device.

The thresholds, without a hidden formula

GroundShiftCheck screening bands for LE
BandLinear extensibility
Low0% to less than 3%
Moderate3% to less than 6%
High6% to less than 9%
Very high9% or more

Exactly 3%, 6% and 9% enter the next band. The same values are used by the address checker.
